Mix the wash/wax cleaner in the bucket according to the manufacturer's instructions, taking into account the dilution ratio of your pressure washer's injector system.
Attach the hose from the water source to the pressure washer intake and attach the outlet hose and trigger wand. Insert the black low-pressure soap tip to the wand. Refer to your pressure washer manual for tip sizes and uses.
Turn on the water source and release the trigger gun for a few seconds, allowing water to circulate through the system.
Place the filter end of the injector hose in the bucket, making sure the filter is all the way to the bottom of the detergent mixture. Attach the other end of the injector hose to the injector tip on the pressure washer pump.
Start the pressure washer, following the manufacturer's instructions. Wash the vehicle with the soap/wax mixture, working from bottom to top using the black low-pressure soap tip. Start with the tip three to four feet away from the vehicle, moving closer only as needed to remove heavy dirt or grime. Soap the entire vehicle, and allow the mixture to dwell for four to five minutes.
Remove the black tip and replace with the white tip for rinsing. Rinse the vehicle, starting from the top and working down. Use caution when working with the white tip, especially when rinsing glass, trim, and mirrors.
Remove the injector tube from the pressure washer pump, remove the white tip from the wand and replace it with the black soap tip. Run clean water through the system until water coming from the wand is clear. Rinse any remaining detergent from the cleaning area before turning off the machine.
Things You Will Need
- Pressure washer
- Wash/wax concentrated cleaner
- Accurately calculate how much detergent to add to the water to save detergent cost, taking into account most pressure washer injectors have a 10-1 to 18-1 ratio of water to chemical.
- Soap/wax detergent cleaners also work well on aluminum, such as boats and campers.
- Take extra time on dirty areas, such as wheel wheels, and don't forget the vehicle's underside.
