New to forum, new to pools. Need to acid wash?

Perhaps mblock22 is referring to Mr. Clean Magic Eraser - foam pads with some abrasive embedded. I don't know what's in CLR but it does seem to do a pretty good job cleaning metal stains in sinks and bathtubs. If I were to use something like CLR in a pool, I would try to retain remove all the runoff to keep it out of the pool water.

You may be right; I dunno.

I do know that some vendors sell products for pool use, without regard for the effects they may have on the pool water or chemistry. So, the maxim, "trust, but verify" might better be modified, "don't trust, till verified"!

[BigDave]

That of course, plus I don't think Mr. Clean pads(magic eraser?) or CLR are marketed for pool use so maybe "You're on your own - tell us what you did and how it worked"

[PoolDoc]

Ah yes. It's the 'official policy' of the PoolForum to recommend that pool owners avoid becoming test subjects for all the dodgy pool products out there. But, if they choose, on their own, to become 'guinea pigs', we certainly welcome their reports on the results!
