This is one of the reasons why people should be very cautious
when taking advise from newsgroups:
1) Phosphoric acid is the principal ingredient in
some versions of Lime Away, which means
that you are suggesting that he use Lime Away
instead of Lime Away.
2) Phosphoric acid is one of the chemicals used for
etching (eating) concrete. Duh.

My water softener has leaked hard water very slowly for some years.

That made the floor damp and caused a buildup of lime on the concrete
floor. The lime is probably not more than quarter millimeter thick but
is unsightly.

My impulse is to use Lime Away, but I expect that that would attack the
cement in the floor.

Is there any good way to get rid of these lime stains?



Phosphoric acid.


I have seen phosphoric eat holes in concrete floors.


Yeah, so? I've seen what it does to human teeth left in a glass of cola
before too. bfd. What do *you* suggest genius?

The OP's not going to get that efflouresence/lime staining cleaned up
off of the concrete without a product that's going to etch, yes ETCH the
concrete *SLIGHTLY*. That's a fact and that's reality. That's not to say
he'll have holes in his slab or pits in it as you and the other dimwit
would have him believe. Phosphoric used properly or in pre-mixed
products such as Lime Away will clean the concrete and not harm it, and
with less potential harm than muriatic or other acid cleaners.

Like the other dimwit you're quick to reply with no advice. Get real. Duh.
