Bosh ChemicalVanish Pool & Spa Stain Remover (2LBS)- Natural Safe Citrus Based, Works Excellent on Vinyl, Fiberglass, and Metals, Removes Rust and Other Tough Stains

This stuff was amazing. Our pool had a green color to it but the water was clear. After taking water to a pool store to be tested and trying what they thought was the problem and still ending up the same I did some research. I found it probably was stain from iron. So I found this product and figured it wasn't going to hurt to try. I followed the directions and honestly within an hour I could see a remarkable difference in the color of the pool. Next day the water was as blue and clear as you would want it to be. It really worked!

We were about to give up. Our vinyl lined pool was stained from winter debris and nothing would fix it: chlorine hock, brushing, vacuuming, more shock...nothing. Crystal clear water, but yellowish-brown stains surrounding the entire pool. Just prior to hiring someone to replace our entire vinyl liner, I found this product on line and figured why not? Within 24 hours, the stains are completely gone from the entire pool. I'm amazed, my wife is amazed, and we're both relieved that we don't have to replace the liner. Whatever is in this product, it works to get out the toughest pool stains, and I'm thankful.

I had a lot of metals in my well water after filling up my pool. I put this product in my pool as directed & the results were incredible. Most of the stains were gone! Awesome product it definitely worked for me!

When we opened our pool this year, there was a ton of yellow staining on the liner. Needless to say, I was not a happy camper. I searched for the cause, then for a solution. I came across this product, read reviews & thought I'd give it a try. UNBELIEVABLE! Within an hour, ALL of the staining was completely gone! The photos don't do it justice. I absolutely recommend to try this; you won't be disappointed.

Works great at removing metal & copper stain on pebble tek pool surface. Easy to use. Turn off pool pump, sprinkle over stain, let is settle and stains instantly vanish. It is a citrus based formula, like vitamin c. This will eliminate your chlorine level and may cause the water to get cloudy due to particulates. Dont panic. Be prepared to follow a process, let it work for a day or two with low chlorine levels, filter out the particulates (several day) clean your filter then add chlorine and get back to normal.

Worked awesome. Water was clear but the pool had a hue to it. Could tell the liner was stained. Used only half of the container and pool liner was clean in less than 24 hours. I have never written a review but this worked so well I just had to write this review.

didnt work as well as i thought. not that great

Follow the instructions to a tea. I did use two containers which equals 4 pounds for my 25,000 gallon pool. Above ground vinyl liner, and you can see the difference. Now I don’t know if the white will come up I’m gonna wait a little while but so far, very pleased with the results.
