Got the rust stains out of my fiberglass pool and spa in minutes. I have tried many other complicated treatments that I had to alter my water chemistry for and nothing worked. The clear view stain eraser was just like a giant pencil eraser and I was able to basically erase the rust stains. It attaches to a standard skimmer pole to reach stains in the deep end. I highly recommend this product.
Stain Eraser for Vinyl Pools is an easy to use stain remover that eliminates most types of stains and deposits including: rust, calcium scale, or calcium deposits without using extra chemicals.
The erasers are soft and will not scratch or gouge pool surface when used properly.
Stain Eraser can be used by hand or attach to any standard telepole.
