Directions

Instructions

Pressure wash surface in low pressure mode for several minutes. Mix one part detergent with twenty parts water (this gallon makes 20 gallons). Place detergent siphoning tube into diluted mixture or pour mixture into onboard detergent tank (see pressure washer owner's manual for instructions). If pressure washer is equipped with a metering valve, adjust to desired setting. Spray at low pressure from the bottom up and allow detergent to penetrate surface dirt for 1 - 3 minutes (do not allow to dry or apply in bright sun). Rinse surface at high pressure with clear water. If needed, use a soft bristle brush to remove stubborn dirt.

Kärcher All Purpose Detergent

I use the Kächer All Pupose Detergent to clean our tile and linoleum floors every other week. Once a year I was the outside of our home. The Detergent leaves the window glass sparkling clean. I sometimes clean spots in our carpeting with it. It leaves a very clean scent. It is my favorite detergent for these purposes.
