DW Dual Wash™

DW Dual Wash™ Cleaner. The best seal starts with a clean surface, and each hardscape surface has distinctly different qualities to remember when cleaning and sealing. DW Dual Wash is a concentrated, non-acidic general-purpose cleaner specially formulated for natural stone and webcast surfaces. DW prepares the surface for sealing by removing ground-in dirt, dust, light grease, oil, and mold-release agents from the surface, which can interfere with proper sealer bonding.


Remember to spot clean with an SRW Specialty Cleaner first, then clean the entire surface with DW Dual Wash before sealing.

Why is cleaning before sealing important? Always clean before you seal for the best sealing results. SRW Products always recommends using PW Paver Wash™ or DW Dual Wash™ before sealing a project. Cleaning solutions pull dirt and debris out, opening up pores and leaving an ideal surface for the sealer to bond, while pressure washing alone drives dirt and debris deeper into the pores.
