Yep, here it is....I don't think it's cheap, but here's the process in a nutshell:

OK,

It is most definitely stain related.

I poured a whole bottle of Vitamin c pills into the bottom of a sock and crushed them up. Got into the shallow end and proceeded to scrub along the wall, the steps and then dropped the sock to the floor, stood on it and dragged it along the bottom and watched as the stain disappeared and the blue liner showed through.

Aside from the method outlined in the previous post, is there a solution that I can buy to add to the water and let it works its magic?

I'll let somebody else answer that question, but wanted to caution you that adding acid to the pool will drop your pH, so make sure it doesn't get too low.....

In that post that Janet linked for you, you can buy powdered Vitamin C in bulk. I've never had to do this but perhaps that is more practical for you than crushing up tabs. Let me ask Ben to pop onto this thread and offer his $0.02.
