CLEANING TIPS

Deck Cleaning

(with or without detergent). Pre-rinse deck and surrounding area with fresh water. If using Kärcher Deck Wash, ap- ply to surface at low pressure. For best results, limit your work area to smaller sections of approximately 25 square feet. Allow Deck Wash to remain on sur- face 1-3 minutes. Do not allow deter- gent to dry on surface. Rinse at high pressure in a long sweeping motion keeping the spray nozzle approximately 3-6 inches from the cleaning surface. Always clean from top to bottom and from left to right. When moving on to a new section of the cleaning surface, be sure to overlap the previous section to eliminate stop marks and ensure a more even cleaning result.

House Siding

If us- ing Kärcher Pressure Wash, apply to surface at low pressure (for best results, limit your work area to sections of ap- proximately 6 feet and always apply de- tergent from bottom to top). Allow Pressure Wash to remain on surface 1- 3 minutes. Do not allow detergent to dry on surface, if surface appears to be dry- ing, simply wet down surface with fresh water. If needed, use special wash brush attachment (not included) to re- move stubborn dirt. Rinse at high pres- sure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 6 inches from the cleaning surface.
