I have some staining that I believe will come off with the use of scrubbing and vitamin C. I know it won't come up with just plain ole' scrubbing, but have tested a few areas with vitamin C tablets in a sock and it appears to be working. The problem I have is 2 fold, 1st the vitamins seems to be used up quickly in the scrubbing with the sock. 2nd is what would be the best solution to get areas in the deep end of the pool. I can't seem to stay down long enough to even be barely effective! That plus I seem to dissolve quite a bit of the tablets just in diving up and down. The pool has a vinyl liner so I'm concern about using a home-made attachment to the end of a pole for fear something may break and tear the liner.
Any suggestions? (I do not have any dive equipment or access to any)
