Pressure washing over the years has developed a destructive reputation, and it's not always the operator, it's chlorine. While homeowners want their patios clean, it’s just not worth the trade-off if harsh chemicals are used. Critter Control offers environmentally safe cleaning solutions. The WashSafe products we use are made from earth-friendly hydrogen peroxide (active ingredient is sodium percarbonate), and it will not harm plants, people, pets, or property. Being an oxygen-based cleaner, the product only has an active life of 3-4 hours before the product biodegrades, making it the safest product in the home exterior cleaning industry. WashSafe is effective in removing dirt, moss, black algae, mold, lichen, or fungi that may grow on patios. We also offer environmentally friendly yet effective sealers for concrete, bricks, pavers, etc. Call 412.767.4067 today for more information or a FREE estimate. Or Contact Us online.
