Natural Chemistry07395 Extra Strength Stain Free, 1-3/4-Pound

I wish I took a before and after because this stuff is magical!!I spent an hour with a brush and a stain eraser pool tool - wouldn’t take any of the hard metal reddish stain.I sprinkled some of this in the steps of the pool and immediately lifted the stain with no brushing. One bottle does about one Inground pool step section. I tried two off the shelves stain and scale and they did nothing.

Best stain remover I’ve used. My pool looks brand new after 24 hours. Based on the reviews, I expected my water to turn cloudy. But, it didn’t. Crystal clear through the whole process. Follow the directions precisely and you won’t be disappointed.

Great product. Does exactly what it says.

Product worked great!

This product never disappoints!

This works great on my pool & I love how fast the ascorbic acid (Vitamin C) takes out the stains, but it is irritating that when I open the bottle that it is not a full bottle. This is expensive & I have to buy it often, so when I only get 2/3rds of a bottle, it irritates me. It is too expensive to not get a full bottle. (fyi: You could purchase Vitamin C tablets, and they might work just a well yet be less expensive).

Amazing!!!! We opened our pool for the season and the sides and bottom were stained brown from the winter. We used this bottle and the next morning the pool was spotless. We have a 13,500 gallon pool and used this whole bottle!!!!!

Works great
