Thoroughly saturate the surface with Wet & Forget on a cool, dry day. Late in the day is best.

For mild contaminations, results can be seen in days. For more stubborn infestations Wet & Forget can take approximately 2-3 months to see improvements. In very severe cases of contamination it may take 6-12 months to work.
Using bleach frequently can quickly speed up the wear and tear on your outdoor surfaces. Furthermore, bleach can harm outdoor surfaces. On the pH scale, bleach ranks at a whopping 13, making it highly caustic. Wet & Forget has a pH of 8, making it nearly pH-neutral and safe to use on virtually any outdoor surface.
Wet & Forget is non-systemic; therefore, if there is runoff into the garden beds, it will not be absorbed into the root system and will not damage plants at all. Wet & Forget won't affect plants unless you accidentally spray directly onto them, which can cause spot burning of the leaves.

Wet & Forget Outdoor Timelines
In the case of green stains, rain should wash them away within a few weeks. So, an April application may be all you need for clean surfaces in May. Black stains can take up to a couple of months, though rainfall can speed up that process.

I used Wet and Forget as directed and it worked its miracles, just as described on TV. At first, it looks pretty ugly if your moss is on cement because everything turns brown. But then the moss disappears - and it stays gone. I also used it on some rubber outdoor mats with similar results.
Wet & Forget's gentle, caustic formula is safe for all shingles and won't corrode your downspouts or harm your lawn with runoff.
Wet & Forget is nearly pH-neutral, so there's no worry about the product affecting your pool's pH. If a little overspray gets into your pool, it will not change or harm the pH of the water. Mix 1 part Wet & Forget Concentrate with 5 parts water in your tank sprayer. Spray the dry pool surround with Wet & Forget.
Chlorine is still one of the most effective killers of algae so doing a super-chlorination of 10-20 ppm of chlorine can go a long way towards wiping out the algae. Liquid chlorine is an ideal shock for algae because it is fast acting and does not add cyanuric acid (CYA) or calcium to the water.
Vinegar is less potent than bleach, but if you have a mild roof algae problem, it can work well while being less harsh on your shingles and the environment. Mix equal parts white vinegar and water, spray it on the affected areas, let it sit for 15–20 minutes, and rinse with water.
Vinegar is acidic so, normally, it's actually used to remove stains. Issues can arise when vinegar is left to sit on decking for too long, as doing so can seep the color out of the wood. Using undiluted vinegar is especially harmful, as the stronger concentration results in even more acidity that can damage your deck.
