A pressure washer with clean water cannot clean the exterior of the house correctly. For you to remove the mold, paint, grease, stains, rust, and all the dirt from the walls you need to use detergents. Pour the detergent into a tank of the pressure washer. Flick the valve to the on position, switch the soap nozzle, and apply the detergent on the surface using a wand. You will find it easier to use a pressure washer that has an onboard detergent tank.
Preheat the surface if it is possible before you apply soap on it after you stick the siphon into the bucket. To prevent the formation of streaks of detergent on the surface apply the detergent from bottom to top. Apply enough soap on dirty areas. Leave the soap onto the surface for more than ten minutes but do not let it dry out. Rinse the surface in a top to bottom motion then switch off the tank valve of the pressure washer, take off the nozzle, or the siphon from the bucket. Here are the types of detergents you can use for pressure washing your home.
House cleaning detergents clean the dirt from siding without bleaching the color of the surface. Wood and steel surfaces can be cleaned using these detergents because they are not harsh. They can be in liquid or powder form. There are highly concentrated detergents for you to buy in bulk and do the mixing from home and save money.
Degreasers are made for cleaning cooking oil and grease from the surfaces. They will leave tough surfaces spotlessly clean. The detergents are used to clean oil and grease in engines of vehicles.
Some people prefer to use vehicle detergents to pressure wash their walls. They are the best detergents for cleaning salts, road films, and unusual dirt from the walls. Be careful not to use them on aluminum and painted surface since they are heavy-duty caustic detergents for cleaning heavy equipment. Use detergent that has wax in them to leave the aluminum and paint surface shinning because they are less abrasive and will cause no damages to the surfaces.
Use detergents that match your budget but can also help you to achieve your cleaning goals.
Go through the warnings of using the detergents before you use them. If you assume the precautions on the package, you may end up damaging the walls of your home by busing the detergents inappropriately. There are bleaching components in some detergents that will fade to the color of the surface.
If the detergents are too harsh, they will damage the pressure wash, which will lead to added expenses of repairing it.
