How to Clean Build-up Off of Vinyl Walls

[SandyRipp]

The stains are pretty stuck to the walls. I tried wiping them with my hand, scratching them, and wiping with a wet cloth. They wouldn't budge, not even flake off.

It's almost like the vinyl walls have a concrete finish!

Sounds like mineral buildup to me, if it was shock, it would have eaten the liner by now.
Use vinyl cleaner on a white scotch brite abrassive pad - use WHITE only since it is the only one that will not harm the liner, teh other colors have abrasives in them.

Hi All, I wanted to follow up on original post.

I've had my pool up for about a month, and the crusty white build-up is gradually going away on it's own. My water has been consistantly at

Alk 80
pH 7.5
TC 1.5 to 2

Thanks for your help!
