Does Wet & Forget work?

I recently used Wet & Forget on some wood siding and haven't seen results, yet. I sprayed it on the house about a month ago and wanted to see if I should give it more time or do a second spraying. Thanks for your help. BTW, based on everyone's response I wanted to post before & after pics either here or on my sight (

    Recent bought some for the first time for vinyl siding mildew. Followed the directions (5 to 1 water to solution ratio), and sprayed the north side of my house. The next day I checked to see if I had wasted my money. I was surprised to see all the mildew

    What's the advantage over bleach?I usually use a bleach/ water mixture. Is this product better for the environment?

      Margaret McLaughlin To apply Wet & Forget to your vinyl siding you would use a pump up garden sprayer. Simply apply, let the product dry and the rain will do all the rinsing and scrubbing for you!

      Mary Absolutely, here's a video on how to remove lichen with Wet & Forget. It requires a second application 15 minutes afterward as the lichen has then opened up and exposed it roots.

    I use it and it does work on any mold (green or black). We live the Seattle area, very wet with lots of green stuff growing. You spray it on when its going to be dry for a few hours, then the rain washes it away. I saw results within a week on my painted

    My asphalt roof is too steep to walk with a tank sprayer. Does W&F work with hose-end sprayers?

    I wonder if anyone other than then vendor could testify to whether it actually removes lichen - moss, mold, algae are somewhat easier to deal with.

    I just spent a day re-sanding my patio and a couple days later followed up with a treatment of Wet & Forget. Now a few spots on my patio are very white, looking almost bleached. Not too happy about it and wondering what I did wrong . . .

    Hi - I'm from New Zealand where this product was formulated from what I understand. You can safely flag it. It is an oxygenated cleaner: the oxygen binds to the mould/grime and weakens its hold, and subsequent rain eases it away. But that's what

    Wet and forget is rubbish and doesn't work, even when you follow the manufacturers instructions!
