How To Pressure Wash Your Garage?

A pressure washer is a very effective tool to help you clean your garage quickly. You can use the pressure washer to wash away all kinds of dirt and grime including oil spots, paint spills, mildew, mold, and more from the walls, floors, and exterior surfaces of your building. 

Pressure washing not only removes tough stains but also helps in keeping your garage clean and good-looking. Just use a high-pressure spray washer to get the job done.

What Do You Need?

You need some essential items to pressure wash your garage. These include a high-pressure spray washer, clean water hoses, and extension cords, cleaning brush, ladder, rubber or plastic gloves, safety glasses and overalls (to protect you from the flow of water), wheelbarrow (to hold all of your tools and supplies), rags and sponges (to clean up afterward), and garden hose (to help you rinse all surfaces).

Consider The Size Of Your Garage

When you are thinking about pressure-washing your garage, consider the size of your building. The largest residential garage door sizes can measure up to 8 ft. by 12 ft., but most residential garages have doors that are 6 ft. by 8 ft. or slightly smaller in size. Walls may also vary in height and width, so you need to consider the measurements of these surfaces as well.

How To Pressure Wash Your Garage?

We will give you exact steps to pressure-wash the exterior walls, floor, and ceiling of your garage. You do not need to be a professional to clean your garage.

The following steps will provide you with all the information you need:

  1. Wear protective clothing, including rubber boots, gloves, and safety glasses or goggles to prevent injuries from water splashes. Be sure to keep children away from the work area because you never know where a pressure washer can spray.
  2. Read the instructions for your pressure washer thoroughly to be sure you are using it safely and correctly and that it is in good working order.
  3. Lift open each garage door, beginning with the one closest to the power source of the water hose so you have easy access to electrical connections if necessary.
  4. Move all mechanical items from the garage if possible, including cars and bikes. Sweep up any loose debris or tools that might be in the way of a high-pressure spray washer’s trajectory.
  5. Set up your extension cords so you have easy access to electrical outlets without having to reach for them under dangerous conditions. Make sure the power is turned off for the electrical outlet before you plug in your pressure washer.
  6. Choose an area to begin cleaning where dirt and grime have accumulated on the walls, on flooring, or on garage doors or windows (if they are made of glass). Some people like to work from one side wall to the other as a starting point.
  7. Before turning on the power for your high-pressure spray washer, turn on a garden hose to the same water source. Leading up to this starting point, get all of your cleaning supplies ready and place them in easy reach. Do not allow children or pets near the work area because you never know where water from a pressure washer can spray.
  8. Turn on the water source and check that all your equipment is properly connected before you start pressuring washing your garage walls or flooring. Cover as much of the area to be cleaned as possible with a light mist of water. Allow the surface to slowly absorb the moisture for up to five minutes, if necessary, depending on the amount of dirt and grime in the area.
  9. Turn off your pressure washer as soon as you are finished cleaning the area, even if it is far before you have completed the job. Otherwise, water pressure can build up inside the home plumbing system or hoses and cause water leaks later on.
  10. Before you switch off the water at the source, turn on your garden hose to drain all remaining water from your lines so no residual pressure continues to build.
  11. While you are still wearing work gloves, move any items that may have been moved for the pressure washing process back into their original places. Be sure to secure doors closed again afterward and look over the area for any signs of damage.
  12. If there is significant dirt that you do not want to remove from the garage floor or walls, consider sealing them first with a paint sealer before pressure washing your garage for a more thorough clean.
  13. Allow your newly cleaned surfaces to dry completely before replacing any tools and items back in their proper places.


That’s all you have to do to pressure wash your garage. It requires an extra level of preparation and caution, but it’s well worth taking the time to do it right in order to produce a thoroughly clean result that will hopefully last for many seasons without having to repeat the process.
