A List of Surfaces That Cannot Be Pressure Washed

Many people use a pressure washer all the time to clean their homes, vehicles, and other things. But to do so safely, you need to make sure that you’re using the right equipment and cleaning the right surfaces.

It’s 7 AM and you’re in your house slippers, the coffee’s brewing, and you’re about to wander out to start your brand new power washing business. Then, you get a call from a customer to wash their floors. However, you didn’t account for surfaces that can’t be pressure washed. What do you do next?

While pressure washing can leave many surfaces almost spotless, certain surfaces cannot be safely pressure washed. This guide will list what those surfaces are.

1. Concrete Surfaces

There are a few surfaces that cannot be pressure washed and concrete is one of those surfaces. Pressure washing can damage concrete by stripping away the top layer.

This can lead to chips, cracks, and other problems. If you absolutely must pressure wash your concrete, be sure to use a low-pressure setting and hold the wand at least six inches away from the surface.

2. Wooden Surfaces

Not all wooden surfaces can be pressure washed because they are delicate or unable to withstand the high-pressure stream of water. The water could damage the wood or cause it to warp.  In some cases, it can also cause the wood to rot.

3. Stone Surfaces

Many people believe that anything can be cleaned with a power washer but that is not always the case. Stone surfaces are one type of surface that cannot be pressure washed.

This includes all types of stone such as marble, granite, limestone, and more. The high pressure of the water can easily damage these surfaces and leave them looking dull and scratched.

4. Glass Surfaces

Glass is a material that is easily scratched and damaged, so using a high-pressure stream of water on it would not be a wise choice. There are other ways to clean glass, such as using a glass cleaner and a soft cloth, that will not damage the surface.

5. Metal Surfaces

Pressure washing is a process that uses high-pressure water to clean surfaces. Though there are benefits of pressure washing, painted or anodized metal surfaces cannot be pressure washed.

You can usually tell if a surface is anodized if it is a different color than the metal underneath. If you are unsure if a surface is anodized or painted, it is best to err on the side of caution and not pressure wash the surface.
