It works

4 days ago
I don’t normally write reviews as I am very sceptical of any of this stuff but this really worked. We had some staining and some moss growing in the grout of our stone patio this spring. I used a pump spray bottle and liberally sprayed the stones knowing it was going to rain the next day. It cleared the stains and turned the moss brown.

I have used this product for the last 3 years. It works as advertised. Gets rid of the moss and stains. I use it on our composite deck, patio paver stones and cemetery head stones. No scrubbing with this product.

Questions

Q: Does it work on glass patio covers?

3 years ago
4 Answers
  • A: I'm not entirely sure what you mean by a glass patio cover, however this product is amazing and we use it on just about every outdoor surface there is to keep it clean/mold/mildew free. The product simply gets sprayed on with whatever type of sprayer you have, & then works throughout the following weeks & months as it rains. Perfect for Vancouver BC area! Lots of rain.

Q: I'm wondering if this product is safe to use on a deck that has been stained. Does it damage the stain? Thanks!

3 years ago
3 Answers
  • A: According to the web site (wetandforget.com), it won't harm a deck's finish. I would suggest visiting the site and reading the FAQ's. I can say that it does an amazing job on concrete and I even used it on the fabric roof of my gazebo last year and it didn't fade the colour, but did get rid of the nasty green tinge.

    A: The active ingredient is alkyl dimethyl benzyl ammonium chloride. We advise keeping pets off surfaces applied to while they are wet from your application. Once the surface is dry, pets can return to the area. Wet & Forget takes roughly 4-6 hours to dry completely.

  • Wet & Forget Expert
    A: Wet & Forget will take roughly 4-5 hours to dry completely. We advise keeping pets off the surface while it is wet from your application. Once the surface is dry, the product is no longer active. The rain won't reactivate the product.

Q: Does it work on roof's moss?

a year ago
2 Answers
  • A: It will kill it but you then have to take the dead moss off the roof. I’ve used it on a number of surfaces and have applied it in late fall. By spring it has mostly gone but may require a second application. I used to use liquid pool algaecide prior to this product and the result is similar. Be patient, it takes months to have an effect.
