Professional Soft Washing Services | Seattle Eastside
Not every surface should be cleaned with high pressure. Soft washing uses low-pressure application and professional-grade biodegradable solutions to safely clean delicate surfaces — killing moss, algae, and mildew at the root for results that last significantly longer than pressure washing alone.
Oasis Restores provides professional soft washing services throughout the Seattle Eastside, using the right method for every surface on your property.

Soft Washing vs Pressure Washing
Pressure washing uses force to remove surface buildup — but doesn't kill the biological growth causing it. Soft washing kills moss, algae, and mildew at the root, producing results that last 2–3x longer. For most home siding and roofing, soft washing is the safer and more effective choice.
