Under Water Vinyl Wall Stains

[doggie]

I'm curious if you have a fiberglass step section. If so, did they stain too?

Hi,

During the winter I didn't have any steps in the pool. I take them out when I close up. This is an AG pool but I have a surround deck.

I'm thinking that you've got some metal staining happening. I've seen a few threads on how to get rid of those. Do a little searching here, you'll find the answers. (sorry, I don't have time at the moment)

You can test to see if they are metal by crushing up some vitamin C tablest and rubbing them on the stain., or use some ph down in a sock and rub it on the stain. IF the stain goes away with either of these, then it is from metals. Let us know how you make out

mbar,

Will this work underwater? I'm thinking that the Vit C or whatever will be washed away immediately upon immersion. OR will enough remain to use this as a test?

I don't want to step on Marie's toes, but a small amount in a small area should indicate whether it's working.

Waste is right, you just need to put it on the stain for a while - you can even hold some in your hand and rub it on the stain. Ascorbic acid (vitamin C) will immediately lift the stain when it comes in contact with it. You will see a little clean spot where the vitamin c hits the stain if it is a metal stain. You can read through this stains and metals forum to read more about it. Feel free to ask any other questions you have
