Mold Moss Mildew Cleaner

Specialty Clean™ MC Mold, Moss & Mildew Cleaner is a concentrated formula that breaks down mold, moss, mildew, lichen, and algae deep-down at its source

MC Mold Moss & Mildew Cleaner

The best seal starts with a clean surface, and each hardscape surface has distinctly different qualities. Whether it’s removing dirt from natural stone or residue from wet-cast, we’ve designed DW Dual Wash to remove ground-in dirt, light grease, oil, and mold release agents to ensure the surface has an optimal bond with the sealer.

Benefits: Breaks down mold, moss, mildew, lichen & algae deep-down at its source | Non-acidic, no-bleach formula | No pressure washing, scrubbing or rinsing!

Applications: Pavers | Concrete | Brick | Shingles | Asphalt | Wood
