Review: Works! - It worked on a stain I had in the pool for years and couldn’t get out. I got scared after I applied it because it turned black, but I left it to do its thing and two days later the black haze was gone and so was the stain!! I was impressed. I don’t impress easily.

### ⭐⭐⭐⭐⭐ THIS STUFF WORKS WONDERS!
*by S***W on July 31, 2025*

AMAZING!! Saved me from a heart attack. I had put a POOL rx in my skimmer on a Sunday took a pool sample to the store on Tuesday and it showed no chlorine. I sprinkled a bag of shock in 2 places in my pool within 10 minutes a had 2 HUGE black spots on the bottom of my pool at least 6'x8'! I immediately put in mineral out it did nothing. I had some of the stain free left over from years ago I had my husband put on a mask and go under to right above the stain and sprinkle it on within 5 minutes the stain began to lift within 2 hours it was completely gone! I just purchased to have on hand in case this ever happens again do not want to be without this product!
