Jack's Magic The Vinyl Liner Blue Stuff

We have a vinyl lined pool, plus we have a well. When you put the two together you will create stains on your liner, steps, etc. We were first told about Jacks Magic from our pool man. It is what he used on our pool from time to time. I now buy it on amazon and avoid the markup in price.

This was a waste of money and time. Didn’t work at all.

great stuff

I've used Jack's products in our pool for years but this time, not so good.In the past, one bottle of anything from Jack's did the trick removing any brown stains in our pool.This year, I've had to use multiple bottles of multiple Jack's products and .... stains are still there.

Did not do much for the stains.

Works great. It takes a little time to get heavy rust stains out. Add the stuff and scrub lightly with your pool brush twice a week and they will come out. It's cheaper at my local pool store though, i pay $12.90 a bottle.

I am giving this three stars because it had little effect however, I have nothing to compare the results with. Maybe I was expecting too much.
