Soft washing is a low-pressure, eco-friendly cleaning method used to remove dirt, grime, algae, and other contaminants from surfaces such as roofs, siding, and outdoor furniture. Unlike traditional pressure washing, which uses high-pressure water to blast away contaminants, soft washing uses a special cleaning solution that is applied at low pressure and allowed to sit for a short period of time to break down the contaminants. The surface is then rinsed with low-pressure water to remove the solution and the contaminants. Soft washing is particularly effective for cleaning delicate surfaces and for removing organic stains caused by algae, moss, and lichen.
