Best Liquid Cleaners for Vinyl Siding
Common household products make for some of the best liquid cleaners for routine vinyl siding maintenance. As with any cleaning of siding, test the cleaner on a small, inconspicuous section first to make sure adverse reactions do not occur with the specific variety. All cleaners should be applied with a soft bristled brush and rinsed clean with a hose. It is best to clean from bottom to top in sections 4 feet wide by 4 rows high. Rinse as cleaning progresses upward and across the house.

Trisodium Phosphate (TSP)
In a bucket mix 1/3 liquid laundry soap with 2/3 TSP and 1 gallon of warm water. This solution will clean just about anything off of vinyl siding. It should be used with extremely tough rust, extensive mold and mildew, or extreme water discoloration. Trisodium phosphate is an excellent household cleaner, however, it is incredibly poisonous. If using TSP make sure absolutely no contact is made with the skin, eyes, mouth, lungs, or just about anywhere else.

Keep children, pets, and plants away from any TSP solution and be sure to cover all glass windows as residue can cause permanent etch marks.
