Wet & Forget Ready-To-Use - FAQs

How long will Wet & Forget Ready-To-Use take to work?

It depends on the type of growth and the intensity of the contamination. If it’s a new growth or a small amount of staining you can see results within days. Otherwise, it may take 2-3 months to see improvement. In the very worst case scenario, where contamination is extreme, it may take 6-12 months to work. Green stains on fencing and walkways tend to clean-up quicker than black stains on roofs or concrete. You can re-apply another application 1 month after the first application to speed up the process.
