How to Apply Detergent with a Pressure Washer

Pressure washers are invaluable tools for tackling tough cleaning jobs, and when paired with the right detergent, they become even more effective. This guide from our team at Crown Cleaning Systems will walk you through the process of applying detergent with a pressure washer to help you achieve professional-level results while protecting your equipment and surfaces.

Choosing the Right Detergent

The first step in successful pressure washing is choosing the right cleaning agent. Not all detergents are created equal, and using the wrong type can lead to poor results or even damage.

  • Choose detergents specifically formulated for pressure washers.
  • Avoid harsh chemicals like bleach that may harm your equipment or surfaces.
  • Consider surface-specific cleaners such as for concrete, vehicles, or siding.
  • Always have the chemical Safety Data Sheet (SDS) on hand for safety precautions.

Preparing Your Equipment

Before you start applying detergent, take the time to properly set up your pressure washer. Be sure to read your user manual for instructions related to your model. Most pressure washers come with a detergent injection system or a soap nozzle. If you’re using a hot water machine, choose a downstream injection system to protect the pump, seals, and coils from potential damage caused by detergent running through them. 

Mixing and Application

Proper dilution is key to achieving the right cleaning power without wasting product. Here are some tips for doing so:

  • Follow the manufacturer’s instructions for dilution ratios.
  • Use a clean bucket to mix detergent and water thoroughly.
  • Prepare only enough cleaning solution for the job at hand.

Tackling Stubborn Stains

For particularly resistant strains, you may need to use some extra elbow grease. After applying the detergent, use a soft brush or sponge to gently agitate the surface to help loosen stubborn dirt and grime. Focus on problem areas but be careful not to over-scrub delicate surfaces. After you’re done scrubbing, be sure to rinse the area thoroughly to remove all loosened debris. 

The Rinsing Process

Proper rinsing is important for a clean, residue-free finish. Here are a few steps to follow:

  1. Switch to a high-pressure nozzle or remove the detergent system.
  2. Start rinsing from the top, working downward.
  3. Adjust the pressure settings to suit the surface you’re cleaning.
  4. Perform a final rinse with clean water to remove all of the detergent.

Pressure Washer Safety Tips 

Always prioritize safety when using a pressure washer. Follow these tips below:

  • Wear appropriate protective gear, including eye protection and gloves.
  • Test on a small area before full application.
  • Keep the pressure washer wand at a safe distance from the surface.
  • Be aware of your surroundings, including electrical outlets and plants.
