9 Things That You Should Never Pressure Wash

9 Things That You Should Never Pressure Wash

While pressure washing is a great way to boost the curb appeal of your home or enhance the appearance of your commercial property, not every surface is safe for pressure washing. A pressure washing expert in Warner Robins, GA, will be the one to identify surfaces that are safe- and unsafe- for pressure washing service provision.

Nine things that you should never pressure wash include these surfaces:

Asphalt Shingles

You should not pressure wash asphalt shingles on your roof as it will remove the granules that protect your roof. Furthermore, the pressure can knock off your shingles, causing repair issues and possibly water damage. A professional pressure washing technician will be able to distinguish the areas of and around the roof that are safe for pressure washing- as well as the best techniques to get the job done.

Stained Wood

It is also wise to avoid wood surfaces such as outdoor furniture. The pressure and heat of the power washer can pull the stain off these surfaces, so they must be done with care and with a special, soft-touch technique that is gentler to the surface.

Lead Paint

Another surface that you should not pressure wash is lead paint. Lead paint should not be pressure washed as it can damage, crack, and strip the paint, sending particles into the air and surrounding area. Lead paint is highly toxic and dangerous; it should be avoided whenever possible and you should not pressure wash these surfaces.

Old Mortar

Weathered brick walls and old mortar can be damaged by pressure washing as it can strip the granules and any other loose material causing further damage to your surface. Avoid old mortar and loose bricks with power washers and, instead, use a gentler cleaning method to remove algae, dirt, and debris from these surfaces.


Thinking about pressure washing a vehicle? Don’t do it; pressure washing your vehicle can cause small dents and chip the paint which can then lead to rust. Use a soft cloth and wash your vehicles by hand for optimal results and the least chance of dents, dings, or damage.


Using high pressure from a power washer on windows can break them and send glass flying. Don’t create a dangerous situation and broken glass; avoid pressure washing windows or other glass surfaces.


Avoid using high pressure to clean your gutters as it can damage your fascia and even knock your gutters loose from the home structure. These can easily be cleaned using a garden hose and inexpensive plumbing snake- or talk to a professional in the area about gutter cleaning services.

AC Units

Pressure washing your air conditioning units can destroy the delicate metal fins which can compromise the airflow. This can also cause water to seep into the AC unit, which could mess up the electrical circuit. Steer clear of your units when pressure washing the house.

Living Things

Though it may seem obvious, you should never, ever pressure wash living things, like humans, pets, or plants. The heat and pressure can cause physical harm by penetrating skin, destroying plants, and causing injury. Be careful.

  1. Pressure washing a car is like sand-blasting it – not only from the high pressure of the water, but also from the minerals in the water. It will take the finish right off.

    There are a few low-pressure washers on the market – they run 100-150 psi vs the 1500-3500 from a standard pressure washer. They have a small (approx 2 gallon) tank which allows use in places not accessible to a faucet and in winter, after hoses have been put away.

We are so pleased, he made our house look brand new once again! He took special care not to dislodge our new mulch and got all of the mildew off of our siding and windowsills. We will definitely be calling him again when we need honest, fast pressure washing.

I recently contacted several pressure washing companies in my area and did some price comparisons. Propel Pressure Cleaning Company gave me a reasonable estimate & that’s exactly what I paid! The service time was prompt, and I was very satisfied with how clean my house was upon completion. I highly recommend this company & I’ll be using this company for my future pressure washing needs.

Jesse was very quick to return my messages, and they were able to fit me into their schedule very quickly. They even came out to do the work while it was raining, so they’re pretty dedicated to getting the job done. I’d call them again in the future.
