Rust Stain Bag Treatment

Fertilizer was spilled in the pool. It did work on new stains, but did not completely remove dark, old stains. It is a very good product. I will purchase again.

Removes Rust Stains

This product is extremely effective at removing rust stains. It does require precise placement of the packet, and you will need to put something on top of the packet to hold it in place. I will purchase this again.

Hurricane Ian stains

Pool flooded with black water and vegetation debri. After emptying brown spots that would not lighten with direct chlorine remained. 2-3 inches. This works pretty well probably took away 75 of the brown spots. Takes time basically one spot at a time

Linda T.
Not effective on dark spors

Product did remove a light stain but did not work on other spots which were darker.
