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?
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.
Clean it, rinse it. Duh. Phosphoric should be considered before muriatic for grout or concrete cleaning because it is LESS harmful. Duh. Get real. Duh. Easiest and safest for the OP to just use the Lime Away. Duh.
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.
Both citric acid and vinegar are good suggests - slower but safer than other methods. The fundamental problem is the fact that the acids which will attack calcium or magnesium deposits will generally also attack the concrete. I'd follow your advise and use something mild and accelerate its action with a brush, followed by a good rinse.
Of course, a painted floor with good paint-concrete adhesion will greatly mitigate the danger of concrete etching. Hopefully the OP has a well painted floor, in which case he has little concern.

Try scrubbing with white vinegar first. If that doesn't do the trick, I think I'd give citric acid a try before moving up to anything stronger.

you might try a high alkaline solution. this seems to work on cleaning grout fairly well without damaging the grout. Check for an aquamix product called heavy duty tile cleaner/stripper I think is the name. It clearly states, "High Alkaline" solution on the back. As always, test in an inconspicuous area if possible. Cheers, cc

This is what this site is for rite? To ask questions because some people don't know. People that think that they are better than keep your 2 cents. DUH......B.S.
