I'm about to start the process of stain removal with Polyquat 60 > Ascorbic Acid > Megic Metal. I've read many posts here, I've read the process. My issue is that I have a lot of staining on the walls, pretty much all the way around. But the process mentions dumping it in the pool, close to the stains. So would the AA in the water also handle the stain removal from the walls? Or is there something special I should do there other than rubbing everything by hand with vitamin C (which would work I guess).
Thank you!
Thank you!
