What Are Some Ways to Clean a Home's Sandstone Exterior?

When cleaning sandstone, use a cleanser that is pH neutral or a solution made from warm water and mild dish soap to avoid stains. When cleaning sandstone, use as little water as possible, as damp sandstone creates an ideal breeding ground for molds, lichen and algae.

Keeping sandstone free of dust can reduce instances of scratches and abrasions. Sandstone is very porous and stains easily. Treating natural stone exteriors with a protective sealer provides enhanced protection and minimizes future cleanup efforts. Sealers fill pores and repel stains, which allows additional time to clean stone surfaces before stains can set in.
