      Rated 5 out of 5 by from Just Unbelieveable Hi, I just happened to see your product while looking for something that would clean up heavy stains all over my pool. In the past I tried a slew of products that never really worked and cost me. I didn't have much confidence in your product but sent for it in desperation. After following instructions I noticed the next day there was improvement and each day after. The one package cleared up about 75% of the stains and I felt that the reason it didn't do more was because my pool held more water than your product recommended so I sent for one more and in one week my pool looks just like the day it was installed 30 yrs ago. One of the best bargains I have had. I wrote my children and gave them the name of your product to be used in the future if needed. I want to thank you guys for such a wonderful product and for saving me a lot of money that we thought we would need to redo the pool. Thank you again

      Rated 5 out of 5 by from works great - cleared up all stains in 3days I had very dark stains on my vinyl siding. It was due to metal the previous owner left under the stairs in the pool. I followed directions exactly and stain free worked great- stains started dissolving right away and were completely gone in 3 days- these were heavy stains. I followed it up with the metal free product as recommended. My pool looks perfect- best it ever looked. If you buy the stain free, be aware it tells you to put fiber in your filter to help it filter out the metal particles. The fiber is easy to find and easy to use. Then use the metal free product as a follow up to insure the metal is gone. Good luck.
