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 (

    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

      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.

    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!

    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

    I have used it on my windsor rock retaining wall and it works beautifully. Takes all of the black stains out, it is on the north side of the house. I have also used it on a natural rock retaining wall and also worked beautifully. Works on siding on house

    I tried W&F and am very satisfied. I live in Charleston, SC and next to woods. I get a lot of mold on the north side of my vinyl siding and this year (4 year old house) I got mold on the south side toward the woods. I tried a popular siding cleaner

    I have used this product on cleaning cemetery gravestones, which are very tough to clean, and found that it works. It takes time, however -- a month or longer. This may be the "holy grail" product we have been looking for!

    thanks for posting this. I heard about this stuff and wondered what and how it did. The commercials I heard do say that it takes time. We have cedar siding with brick facing about 4 ft up. Is it really expensive? I haven't seen it in the stores.

    Does this have a money back guarantee? Don't see any results after application.

      Mark Would you be able to share a photo of the growth that's on your wood patio? Is it moss? Most organic growths such as moss, mold, mildew or algae are easily taken care of with Wet
