How to pressure wash hardiplank siding.

A pressure washer can quickly ruin vinyl siding by cracking it with the high pressure stream of water so it s necessary to know which pressure level and nozzle to use. Once the siding is completely sudsed up use a garden hose to rinse the area. Do not allow soap or cleaners to dry on the siding. Rub the oil or grease off the siding.

Choose a pressure washer. If you re spraying mold and mildew off of your siding you should use more than just water. If the dirt on the home is minimal then try the soap and brush method with a garden hose first. Dip a soft cloth into the mixture and saturate it well.

Use pressures under 1500 psi. Clean the stained siding while rinsing your cloth frequently. Mix a mild dish detergent and water in a bucket until you have sudsy water. Starting low and gently working your way up is the safest bet.

Keep a minimum distance of 6 feet from the wall. It s best to avoid pressure washing if you can since it can result in damage to the siding finish. Instead continually rinse the area until all of the soap has washed off of the siding. You may need to repeat.

Rinse out your cloth in the bucket frequently to prevent grease and oil buildup.
