The pressure washer should operate with a pressure level set below 1,500 PSI because higher pressure could damage the siding. Vinyl siding requires either commercial vinyl siding cleaner or water and gentle detergent mixture which should be applied through spraying. A pressure washer should rinse the siding while maintaining the nozzle at a minimum 12 inches distance from the surface.

Method 4: Homemade Cleaning Solutions

An appropriate cleaning solution can be made from equal parts water and white vinegar which you should mix in a standard spray bottle. Apply the solution on the exterior surfaces followed by a 10-minute wait then scrub and rinse completely.

A bleach solution consists of one cup of bleach together with one gallon of water. Soak siding with the solution by using either a sponge or sprayer then scrape it before conducting a thorough rinse. Apply bleach cautiously as a test solution should appear first on a tiny area.
