BioGuard Erase Iron Stain Remover, 1.75 lb, Highly Effective Iron Stain Remover, Restore Pool Surfaces, Suitable for All Pool Types

This stuff is magic at removing iron stains on a pool that has not been looked after the way it should be! Just shocked at what a great job it does!

Excellent product it worked ! Took all of the brown iron stains off my pool stairs and sides if the pool .

The media could not be loaded. We have scrubbed and used many things to get our steps white again with no luck for the last 4 years!! I was up late one night and seen a TIkTok where someone had used this product. I figured what could it hurt. This stuff is AMAZING and I would and do recommend it to everyone!! You will not be disappointed,

I know for a fact my problem is excess iron. Paid $52.00 and it did nothing, literally nothing! Very disappointed and would not recommend it.I

I got my pool perfectly balanced and BOOM! Metal stains all over the fiberglass pool. We saw this on a You Tube video and ordered it along with the metal magnet and Sparkle Up. As soon as the Stain Erase hits the surface of the pool, the stain disappears like magic. Amazing. Followed the directions and our pool is back to looking beautiful.

Great product ! I had stains that a licensed pool professional couldn’t get out. One treatment and the stains are gone!

The product did remove stains from the pool walls and steps, but I believe there has been a negative reaction with Cal Hypo (granular chlorine). When I add cal hypo, water turns green. I also used CuLator to remove the copper and iron from the water. This product does not remove metals, it is a sequestratrant so the metal ions must be removed. If you use this, only use liquid chlorine in your pool.

Product worked great; but expensive.
