Many homeowners and business owners choose to rent or purchase their own pressure washing equipment instead of contracting with a power washing company for cleaning services. However, in order to choose the best pressure washer for the job – and to use it effectively – it’s important to understand the three primary pressure washer ratings: PSI, GPM and CPU.


This number tells you how forceful the water will be during cleaning. The higher the PSI, the greater the cleaning power – and the greater the potential for damaging your property. Most pressure washers offer a range of PSI settings, typically from 1,500 on up to 4,000 or more. (As a point of comparison, a garden hose typically operates at 40 PSI.)

The pressure washer with the highest PSI setting isn’t always best; rather, you should choose a model that offers a range of suitable settings for the tasks you need done. For most homeowners, a high end of 2,250 PSI is sufficient. More than that, and you may be wasting your money.


GPM measures how much water a pressure washer uses during each minute of pressure washing. At first glance, you might think a model with a lower GPM would be more efficient and thus more desirable; however, the opposite is generally true. The higher the GPM, the less time it will take to complete your pressure washing job. For example, a 4-GPM pressure washer will wash away grime in half the time of a 2-GPM model.

Ultimately, a higher GPM can potentially save you both time and money (on fuel or electricity to power your pressure washer).


Multiplying PSI by GPM gives you the CPU, also known as Effective Cleaning Units. Calculating CPU is a handy way to compare pressure washing models at a glance. If the CPU is high, you will have a better probability of investing in a pressure washer that is efficient and successful.

Of course, hiring a power washing company to clean your home or commercial property will eliminate the hassle of purchasing a new washer. Plus, professionals are experienced and are trained to clean efficiently without harming your property. However, if you’d rather do the job yourself, understanding PSI, GPM and CPU is a good place to start.


Certain areas of life are nearly impossible to imagine without modern technology. For instance, before the advent of the washing machine, washing a family’s clothes took an entire day of scrubbing, twisting and rinsing. Likewise, pressure washing for trains has dramatically changed the way people think about rail car cleaning. For the first hundred years or so of train history, cars were washed in a pull-through building that modern thinkers would probably associate with a car wash. Today, however, engineers can rely on pressure washer services to keep trains in tip-top shape – regardless of whether there’s an open washing bay nearby.

Pressure washing for trains includes cleaning the exterior, engine, carriage, wheels and even the interior, depending on the type of train. (The interior of box cars may be pressure washed, but passenger trains will require gentler cleaning approaches. Most pressure washer services are happy to apply these less intense cleaning styles.) Graffiti may also be removed with the proper pressure washer services. Many pressure washer services also include a de-greasing solution to prevent future grime buildup. One caution: Pressure washing for trains should not include the locomotive. Pressure washing professionals should cover locomotives with tarps before washing the rest of the train. This is to protect locomotives’ brake systems; repeated exposure to water can corrode and eventually destroy disk brakes.

A pressure washing approach to rail car cleaning has many advantages, including:


This classic motivation for outsourcing services also applies to pressure washing for trains. Many rail managers have chosen to switch from in-house cleaning to outsourced pressure washer services to save money. Specialization typically improves job performance, and pressure washing for trains is no exception. Because pressure washing is all they do, many pressure washer services can undercut traditional employment costs. By hiring out cleaning duties, management can save money on employment taxes, benefits and other labor costs.


A whole unit train includes 125 cars, equating to an incredibly large surface area that must be cleaned. Many rail yards aim to clean a one-unit train in five days. However, because they specialize solely in pressure washer services, professional pressure washing experts can usually complete the enormous task of washing a train in four days. This means more rail time and less downtime – bringing even more cost savings and profit.


Oftentimes, trains are cleaned only when they need repairs or maintenance. This is a shame, since a clean train not only improves employee morale, it also improves the public’s perception of the train industry. Finally, a clean train is usually a faster train, since all that dirt and grime adds unnecessary weight to the whole unit. However, time and equipment constraints limit how often trains can be cleaned in wash bays.

When it’s not possible to run a train through the bay wash, pressure washer services can step in. Pressure washing for trains requires certain equipment, including lifts to reach the top of the train as well as a waste management system. Assuming you select a prepared rail car cleaning partner who has his or her equipment ready to go, you should be able to achieve mobile train cleaning, even if there’s not a wash bay nearby. With more frequent washing, your trains will be faster and more appealing overall.


Graffiti is an eyesore that just grows larger and uglier with time. As soon as one tag appears on a train, others are sure to follow. Fortunately, pressure washing for trains can include graffiti removal and prevention. Anti-graffiti solutions can even prevent future tags from appearing.


Some pressure washer services are dedicated to environmentally conscious operations. Such forward-thinking organizations capture their wastewater, since the water coming off of dirty trains is usually quite polluted with engine chemicals, road dust and more. Wastewater from cleaning trains can taint local watersheds if not collected. Green pressure washing companies also use earth-friendly cleaning solutions to wash trains.

From saving money to saving the earth, there are many advantages to cleaning trains through outsourced pressure washing. One last benefit: Many pressure washer services are also capable of painting trains, so you can take care of even more maintenance tasks at a time.

Does Pressure Washing increase my water bill?

Does Pressure Washing increase my water bill?


Will pressure washing increase my water bill? in short yes. in Edmonton Alberta the average household pays approximately $38.16 per month for water services. The water consumption is typically based on m(Meters Cubed). Looking at the rates for a large 8 gallon per minute pressure washer, there is a few calculations to finish the equation. First we have to convert gallons per minute to Meters Cubed.

Based on the 8 gallon per minute pump it will use approximately 0.0302 m3 per minute. In Edmonton the rate for consumption is as follows:

0 m3 – 10.0 m3 $2.1290
10.1 m3 – 35.0 m3 $2.3260
Over 35.0 m3 $2.9397

Based on those numbers. You would have to use up to 10 m3 , Which will cost you approximately $2.13. That is 2,641 Gallons. If your pressure washer runs at 8 gallons per minute you will have to divide 2,641 by 8. That will give you 330 Minutes(5.5 hours) for $2.13. You could run your Pressure washer for 19 Hours and it will cost $2.94. That extra will indeed be included on your next few bills. For this reason we prefer to use our customers water if it is available and clean (not from a well) as hauling water does get very expensive. The price for hauling water varies from each county and can affect your invoice. Check your local water prices and compare to see the difference.

Is it OK to Pressure wash a wood deck or fence?

Pressure Washing a wood deck or fence

When you are looking to pressure wash a deck or a fence there is a few things to consider.

  1. How much pressure to use when washing your deck. Even small pressure washers can have enough PSI to gouge or damage your deck. See: A BASIC GUIDE TO PSI LEVELS
  2.  The tip you intend on using. Using a red tip is a definite absolutely no-no. If you are going to use at tip on the wood, Use a 15 degree tip (yellow) and keep approximately 6 inches away from the wood at all times. Check out our quick guide to Pressure washing Nozzles

We would not recommend you pressure wash your deck. You run the risk of damaging your deck if you are not careful with how close you get to the wood and the potential of leaving “Zebra” stripes in the wood. This is caused by stop and start points where you left off and started washing the board again. You may not be able to see it when the wood is wet, it will show later when it dries. I would suggest “soft washing” the deck. Soft washing is using chemicals to remove organic growth and bring back the natural wood color.

Do I have to Seal my deck after Pressure Washing?

I would suggest you seal your deck approximately 24 hours after it has had time to dry. Some stains can be applied even with moisture in the wood, but these are very rare to find.

If you are looking for a restoration service give us a call and book time to get your deck and fence done!

How many gallons does it take to soft wash a house?

Estimating how many gallons to soft wash a house:

This is for General information and obviously we would recommend hiring a professional company to complete the work.

Soft washing involves using low pressure water, a surfactant and Sodium Hypochlorite to Clean off dirt and grime from your building. Depending on the pump volume for example a 5.5 gallon per minute pump will require up to 5.5 gallons of water to operate. If it takes you one hour to spray your house, you will have used approximately 330 Gallons (5.5*60 minutes) spraying your house for the entire hour at full speed. This number will go up or down depending on the Pump volume per minute, which should be located on your pump or in your owners manual.

Estimating how much Sodium Hypochlorite follows the same formula. The difference will be what your mixture is being downstream. if you are using 50/50 (50% SH/50%water) then you will be using approximately 2.75 Gallons of SH per minute or what ever your pump is rated for and approximately 2.75 GPM of water. The flow rate is based off of optimal pump production at full speed. Adjusting your rated based on the operating speed is required. Estimating this is based on how much time you spend actually spraying with the mixture.

Similarly when using a surfactant to downstream you will follow the same formula. If you are running 40/10/50 (40% Water/10% Surfactant/50 % SH). 5.5 gallons per minute will be 2.75 gpm SH, 1.1 gpm of Water, and the remaining will be surfactant (1.65 gpm). This is an Extreme example for reference.

IT is important to realize that down-streaming is AFTER the pump if using a pressure washer. You do NOT want to run SH or anything else other then water through a pressure washer. This can damage the pump, pump seals and etc.

These settings should only be used if you are soft washing Brick or Stucco.

Check out our page to give you more information on the POWER WASHING DOS AND DON’TS


For a normal Vinyl house or combination of, you can pre mix about 10 oz of your choice of surfactant for every 5 gallons and downstream that mixture. It does not need to be a “HOT” mixture if you do not need it. Our recommended Procedure is to BATCH MIX. You can wash approximately 4000 sq. feet with this 5 gallon Mixture if used correctly. Downstreaming as described using a pump and pulling directly into the hose from containers and mixing valves may result in using more chemical then what is required to complete the job if you do not know what you are doing. 

ALWAYS follow the recommended Personal Protective Equipment Guidelines for whatever Chemicals you are using.


Complicated mixtures? You may want to call a professional pressure washing/ soft washing company to complete your job.

By this time of year, most privately owned pressure washers have been put to bed for the winter. However, if you’re one of those die-hards who keep on pressure washing even throughout the winter, there are a few precautions pressure washing companies recommend taking in cold weather.

Pressure washing must be done carefully when you’re outdoors in very cold temperatures. Among many other risks, you don’t want to deal with freezing water or, worst-case scenario, hypothermia. Here are some tips to keep you brave pressure washers safe while pressure washing in winter:


Be wary of getting ill when outdoors in the rigid temps. Hypothermia can take place even when land temperatures are above freezing. If you already have a cold, it’s best to avoid venturing outdoors with your pressure washer. Most pressure washing companies are experienced at working in cold temperatures and can do the job for you much more safely.

Winter pressure washing should take place during the warmest part of the day. Bundle up to take care of your health – wear warm clothing as well as a hat and gloves to protect your skin. It’s also important to warm up with plenty of indoor breaks.


Another thing pressure washers should keep in mind is that chemicals are less effective in cold weather, which is why it’s best to accomplish pressure washing tasks during the warmest part of the day. You can also consider a hot water rig. Powdered chemicals will mix much better in hot water, resulting in a quicker cleaning job – and less time spent out in the cold.


You don’t want damage to your pressure washer’s pump, and this is very likely to happen during the winter unless you take extra precautions while pressure washing. Frozen water in a pump expands, and any remaining liquid in your pump can damage your equipment. To avoid parts from rupturing, pay attention to the following tips:

  • Store the pump in a warm area so it does not freeze during the winter.
  • Use compressed air to release the remaining fluid in your pressure washing equipment.
  • Run a blend of 50 percent antifreeze and 50 percent water through your pump.

You should also be careful while pressure washing in freezing temperatures, as water can freeze behind you and cause a nasty fall.


Pressure washing professionals always take into consideration, when choosing the right pressure washer, the nozzle, power source, reliability and other features. One of the more important considerations however is the water that flows through the pressure washer. Power washers typically come in two types: cold water and hot water. Each is used for different reasons and offer different benefits. Below we explore both options and their applications.


Because the water does not need to be heated by your pressure washer, cold pressure washers do not have a burner. The temperature of the water won’t change as it goes through the system. These pressure washers are smaller, cheaper, safer, and more portable.


A cold pressure washer is perfect for rinsing your siding or sidewalk, as long as the surface has no major oil stains. When removing sand, dirt, or paint, you can use a cold pressure washer as well.


Hot pressure washers send water through a heating coil before blasting it onto the surface you want to clean. Recall from your childhood science classes that the molecules in hot water are moving much faster than those in cold. The strong energy in hot water reduces the water’s surface tension so it can penetrate grease and dirt more efficiently. By the time the water comes out of the nozzle, it could be as hot as 200 degrees Fahrenheit. Therefore, hot pressure washers clean better and faster than cold pressure washers. They can also cost twice as much.


If you need to clean an impenetrable surface, like concrete or brick, hot pressure washers will make the job quick and simple without causing damage. This is especially true if the surface has oil stains or gum stuck to it. A hot pressure washer can also help save money in the long run by finishing the job more effectively and quickly and by requiring less detergent.

If you’ve got some quick, light cleaning to do around the house, cold pressure washers are your best bet for safety, portability, and upfront cost. But i.f you’re looking to tackle a big, oily, industrial job, consider contacting your  pressure washing service to get the work done fast, with the right equipment.


Power washing is an incredible thing. With only a few blasts from your power washer, years of grime can be swept away. However, it’s important to understand how to properly use such a powerful tool in order to avoid causing damage to your business or personal property. The power washing dos and don’ts listed below will help you understand how to best use your pressure washer. We’ll also discuss when it’s smart to contact a power washing company for professional help.


Do protect yourself and others. Remember, this machine is exuding water at 1,500 to 3,000 PSI. When you’re dealing with such high water pressures, it’s not unusual for sharp particles to fly off the surface being cleaned. Don’t risk permanent eye damage – wear protective eye goggles when using a power washer. For especially hazardous jobs, power washing company managers often require employees to wear full face masks. It’s also smart to wear long-sleeve clothing, just as you would when using a weed whacker.

A little more safety advice: Be sure family members and pets stay far away from the spray of your pressure washer. Finally, avoid accidents by engaging the safety lock whenever you’re not in the middle of power washing.

Do check oil levels before turning on your power washer. Running any engine without oil will cause lasting damage. Be sure to check oil levels in your machine before power washing. Your owner’s manual should have additional maintenance instructions.

Do notice the distance between the surface you’re cleaning and the tip of the power washing nozzle. Different cleaning surfaces will require more or less space. When blasting built-up BBQ gunk off of your grill, you can hold the nozzle as close as three inches away. The highly pressured water emitted from a power washer won’t damage a metal grill. However, other surfaces will require more space. When cleaning the exterior of a home, for instance, you should keep the nozzle at least six inches away from the surface being cleaned. In general, it’s best to be cautious – start farther away, and move closer once you see that no damage is occurring.

Do conduct power washing tests first. If used incorrectly, a power washer can cause permanent damage to your home or business. Therefore, if you’re unsure about the correct pressure setting, cleaning agents, nozzle type, water temperature or nozzle distance for any job, you should test a small, inconspicuous area first. Alternatively, you can call in a power washing company to show you how to properly clean a particular surface.

Do store your power washer in a climate-controlled area with good ventilation. If your machine will be kept in an unheated room, conduct winterization to avoid damage caused by freezing temperatures.

Do clean out your chemical injector after every use. Built-up chemicals will only cause problems down the road, so be sure to flush out your machine after using the chemical injector.


Don’t power wash windows. You’re just asking for trouble if you try power washing windows. They can crack or break, and weather seals can be destroyed. Moreover, manufacturer warranties are typically voided if the owner uses a pressure washer to clean windows.

Don’t add fuel while the machine is running. Just as you turn your car engine off before adding gas, you should turn off your power washer before refueling.

Don’t leave your pressure washer running unattended. If your machine is on, you should be right next to it.

Don’t point your power washer at animals or people. Basic safety protocols advise against aiming any powerful tool at fellow living beings, even in play.

Don’t use acid-based products or bleach with your chemical injector. This is both to protect your machine (which can be irreparably damaged by such liquids) and to protect people and pets (who could be seriously hurt by these chemicals). If your machine isn’t powerful enough, call a power washing company instead of tinkering around with dangerous chemicals.

Don’t use hot water unless it’s approved in product specifications. Some pressure washer pumps are rated for hot water, and others aren’t. Don’t use hot water unless you’re certain your pump is made for it. If not, a power washing company will have the tools needed to clean the surface in question.

Don’t leave your pressure washer running for more than two minutes without pulling the trigger.


A service vehicle is more than just a means of moving goods from one location to another. It’s also a mobile advertisement. Customers and clients associate the state of a company vehicle with the quality of the brand itself. Over time, road grime will inevitably build up on any company vehicle. If dirt is left on a company truck or van, customers may make negative connections with the brand. Therefore, it’s important to keep company automobiles in tip-top shape.

Fleet pressure washing is the best approach to keeping company cars and trucks clean. Pressure cleaning is effective, rapid and, assuming you choose an earth-friendly pressure washing service, safe for the planet. (Green pressure washing for trucks and cars involves sucking up water runoff before it can impact local watersheds, as well as using only earth-friendly cleaning supplies.) The tips listed below will help you achieve superior fleet pressure washing results – or, if you’re planning to hire a pressure washing service, they can act as quality checkpoints.


Some road grunge requires extra-strength cleaning supplies. For instance, sections that are covered in oil or grease should be presoaked in a degreasing solution. Areas under the hood and truck tend to pick up especially “sticky” grime, so be sure to presoak these zones.


Pressure washing for trucks and trailers requires a machine that can deliver at least 2,000 psi of water pressure.


To begin, rinse the entire exterior of your truck or van. As a pressure washing service professional could tell you, this will go far toward removing dust from your vehicle’s exterior.


Those who regularly provide pressure washing for trucks recommend tackling different sections at a time so you can clearly track what has been washed. Once soap has been applied, let each section sit for five to eight minutes. Avoid letting the surface of your truck or van dry completely, as this can cause streaking. As you wash, work from top to bottom, and be sure to rinse each section with generous amounts of clean water.


Specialized pressure cleaning chemicals can make fleet pressure washing much easier. However, if you care about preserving the environment, you should know that not every pressure washing service uses earth-friendly cleaners. Why does this matter? Because non-biodegradable cleaners sweep into street drains, and from there into local streams and rivers, where they poison local species and disturb ecological balance.


Another major environmental concern with pressure washing for trucks and other company vehicles is that the water runoff is highly hazardous for local water sources. If at all possible, you should capture your washing runoff to prevent oil, antifreeze and hundreds of other toxins from sweeping into nearby streams. (Or save yourself the hassle and hire a professional, earth-friendly pressure washing service.)


Some companies employ large tractor trailer trucks for transporting goods across the country. Given their dimensions, these enormous vehicles can be especially difficult to clean – after all, few of us are tall enough to reach all the way to the roof of a semi-truck. A pressure cleaning attachment can solve this problem. Specifically, you’ll want to use a telescoping wand extension to add length to your pressure washer. It may be tempting to set up a ladder instead, but this is extremely dangerous because the pressure of the washer can easily knock a person off such precarious footing. For true pressure cleaning connoisseurs, a flex tubing extension will allow you to create a ninety-degree angle so as to reach easily underneath vehicles.


Let’s face it – pressure washing for trucks and vans isn’t easy. If you’re unsure of the right pressure settings, you can cause permanent paint damage. And even if you have a perfect understanding of pressure cleaning, fleet pressure washing is physically demanding and time-consuming. A pressure washing service can usually save you money and time while delivering superb results.

Beyond creating a positive brand image, a clean truck is a safe truck. That’s because clean vehicles reflect more light, making it easier for drivers to spot your fleet. Furthermore, dirt-free automobiles are easier to maintain, since built-up soot, oil, dust and dirt tend to gunk up engine components. To see the full benefits of a clean fleet, pressure washing service professionals and amateurs alike should follow the suggestions listed above.



Graffiti is a stubborn eyesore. Because paint can penetrate deeply into porous wood and concrete surfaces, graffiti cannot typically be removed with conventional cleaning approaches. No amount of elbow grease will allow you to remove graffiti with just soap and water.

Sometimes it is possible to quickly repaint the surface that has fallen prey to tagging; some cities even employ paint crews to quickly paint over fresh graffiti. However, as many business owners appreciate, sometimes it’s just not possible to paint over a tag. Not all surfaces may be repainted; if the street-facing side of your business features a brick exterior, for instance, painting over graffiti probably isn’t an option.

In such circumstances, pressure washing can be a godsend. Pressure washers can emit water at 300 times the power of a standard garden hose. Oftentimes, this is enough to loosen and lift paint. If traditional pressure washing isn’t effective, graffiti removal service providers may be able to remove the graffiti by pressure washing with a specially formulated, environmentally friendly cleaning agent. Many pressure washing cleaning formulas contain nano-level technology to break apart paint at the microscopic level. For this reason, it’s smart to hire a pressure washing company when attempting to remove especially intractable graffiti.

Below, we’ve gathered tips on how to use pressure washing to remove graffiti, especially from commercial buildings:

Choose a high pressure setting. Pressure washers offer adjustable pressure settings; for graffiti removal, you will probably need to adjust your washer to a high pressure setting. Don’t overdo it, though – too much pressure could wear away the surface you are trying to clean. Some recommend pressure washing at a setting of 3,000 PSI when removing graffiti; this may vary according to the paint and the surface to be cleaned.

Don’t work in very cold or very hot temperatures. Many paint removers do not work well when the ambient temperature is extremely high or low.

Set your pressure washer to a high water flow setting. The rate of water flow is another setting that may be adjusted on pressure washers. For removing graffiti, it’s best to have a high rate of flow, around three to five gallons per minute. Again, don’t go too far with this; slowly ratchet up the rate of flow until the graffiti begins to lift. Avoid jumping directly to a very high pressure or water flow setting; instead, slowly increase pressure to the absolute minimum required to remove the tag.

Consider adding heat and/or steam. Heat and steam have long been recognized as powerful ways to strip paint from interiors. Similarly, graffiti paint may more easily be removed with heat and/or steam. Both heat and steam soften paint film, making it easier to lift the paint. Modern pressure washing machines can deliver heated water at temperatures as high 330 degrees Fahrenheit, which helps break down and remove grease and other substances. Again, don’t go directly to the highest temperature available on your machine; experiment until you find the lowest possible heat or steam setting that will remove the tag.

Choose the right cleaning agent. As conservators can tell you, each exterior surface has its own cleaning requirements. Masonry will require different cleaning solutions than wood, and different types of masonry require different types of cleaners. Research your building’s exterior to figure out which type of cleaner to use. Then follow the manufacturer’s instructions to avoid causing permanent damage.

As an example, alkaline paint removers require a pre-wetted surface to work. In contrast, solvent-based cleaning products are incompatible with water. (If you’re at all concerned about the possibility of damaging your building’s exterior, it may be best to simply hire a pressure washing company for graffiti removal service.)

Start at the bottom and work your way up. As you apply pressure, heat, steam and cleaning agents with your pressure washing machine, work upwards. That way, you’ll avoid staining lower surfaces.

Generally, it is best to hire a graffiti removal service when attempting to have tags removed from the exterior of your home or business. Graffiti removal service professionals understand how advanced pressure washing technology, such as heat, steam and specially formulated soap, can work together to quickly lift graffiti from nearly any exterior surface. Rather than struggling to patch together a haphazard education on pressure washing, consider hiring a pressure washing company that offers a specialized graffiti removal service. This approach will save you money, time and irritation down the road.
