Each type of surface and the type of contamination will help determine the right chemical to use for your project. No single chemical will work on every job, so it’s essential to properly do your research before each job or hire a professional.

When to Use a Pressure Washer

Here are some projects you might be looking into for a pressure washing project:

  • cleaning a driveway 
  • cleaning the exterior walls of your house
  • cleaning sidewalks and walkways 
  • cleaning your garage floor/door
  • clean your deck
  • stripping paint 
  • power washing your car, truck, or SUV 
  • power washing the roof shingles

There are many chemicals used, but below are some of the most common ones used:

Sodium Hydroxide (Lye)

Sodium hydroxide is found in numerous products we use on a daily basis, such as soap and many household cleaning formulas. It is most effective as a degreaser that works well on metal, glass, and other materials.

Sodium Hypochlorite (Bleach)

In low amounts and highly diluted with water, this chemical is used to disinfect, especially for mold or mildew. It removes stains and keeps them from coming back. This chemical works well on steel and glass.

Ammonia (Sodium hydroxide)

In most cases, ammonia is effective in cleaning glass or stainless steel. But it is usually a secondary option compared to other cleaners used in power washing.

Citric Acid

This type of cleaner is suitable for removing stains and rust from concrete, wood fencing, decking, etc. It is considered one of the safer options for removing stains from the driveway.

Oxalic Acid

Most pressure washing companies start with one of the previous methods and finish with oxalic acid. It is great for getting deep stains and discoloration from porches, patios, and other concrete surfaces. Additionally, it proves to be useful in the removal of rust, calcium, and water stains.

As mentioned before, these are just some chemicals that can be used for the pressure washing process.
