WHY IT'S PERFECT FOR YOU

Wet & Forget Exterior takes the hard work out of cleaning outdoor surfaces. Dilute the concentrate, spray onto dry surfaces until saturated, and leave it. Rain and UV break down the growth gradually over the following weeks — no ladders for scrubbing, no high-pressure hose required.
