      Rated 4 out of 5 by from Works great This product really takes the rusty looking Material off all my plastic stairs and blow out tubes and filter the only problem is comes back in 10 days to 2 weeks literally just as dark as before but for a week and a half I have perfectly white everything I have tried everything to clear the pool with the exception of one thing which might be the problem because in 10 years of having this house I have never had this problem until last year the only thing I have not done is changed the sand in the filter in the pump. Which I will do before I get and install this product again. so again it works great I just get it reoccurring and that's the only thing left I think I can do

      Rated 5 out of 5 by from It worked wonders I purchased this item because I couldn't find the stain remover that I had used in the past. I was not expecting it to do much but was extremely pleased with the results. As soon as I sprinkled the powder on the stained brownish color stairs it started working on the stain (from well water and sooo much rain lately). By the next day our white stairs were back to brand new sparkling white.

      Rated 5 out of 5 by from Works great! Opened our fiberglass pool to metal stains-solid light brown stains everywhere the water was. Could not scrub off so we tried this. Sprinkled it in and the stain disappeared before our eyes. Went trough 2 bottles and had to order a 3rd but worth every penny!

      Rated 5 out of 5 by from Works wonders! It completely removed all stains, even hard water rust from the liner within 24 hours.

      Rated 5 out of 5 by from Wow, the stain is gone I had to put a lot of well water into my pool this year. It left a brown stain on the walls and floor of my vinyl liner. I followed the directions and sprinkled the product into the pool onto the stains with the pump turned off in the evening and the pool chemicals at the levels indicated. I saw immediately there were dots where the product started working on the stain. I went to be hoping that it would at least get some of the stain off. When I went out in the morning the liner was a vibrant blue and the stain was 99 percent gone. Except for some spots on the walls and in the corners. I am putting metal free in today and will probably repeat the process just to get the very few remaining spots. Very satisfied with this product.
