BioGuard Erase Iron Stain Remover - 1.75 lb

This product does exactly what it says it will do. The only problem this time was company changed the label on product %26 didn't t mention it so I thought I was sent the wrong item. After writing to company I was told due to updating of packaging product was exactly what I ordered just different label. Should have been told that from beginning. Great product %26 cleaned the inside of my pool as expected. Will be purchased every year when needed, due to high iron content in my water I need to use this product. There is also another product I need but company made mistake %26 omitted from previous order so I had to reorder %26 wait again. Only problem I had.

This product is amazing! My pool had brown/orange stains over the entire liner. I poured this product around the edges, and the stains INSTANTLY disappeared!

Works right away, no more yellow stairs

Arrived quickly. Removed almost all of the rust stain from the pool within about 72 hours. Anything that remains, you wouldn't see if you didn't know to look for it. If you have an iron stain in your pool, this stuff really works. Our pool is salt water. We got some clouding but adding more salt removed all of the clouding. Also, it had rained a lot so the clouding could have been from the rain.

This product is a MUST if you have a pool with slight discoloration by years end or years opening. It works like magic and you will definitely be impressed. Just ensure you put the correct amount according to your pool size. See the videos on this product — it's my go to every time.

After using the normal products used, used erase to remove a very bad iron stain on pool liner. It worked! Cannot complain about success. Extremely pleased with this product.

This stuff is the only thing that we have found to take out iron stains. It works instantly. We have a lot of iron in our well water so every time we have to add water, iron stains appear, this stuff takes care of every stain. I highly recommend.
