    phosphoric acid is probably the ingrediant in Lime away, that is what is smells like. Vinegar would probably work as well

    Lime away, aka CLR is glycolic acid solution, I guess it is used because it is a mild organic acid (kinda like citric but with an alpha hydroxy group) yet it is strong enough to dissolve basic deposits in a reasonable time.

    A cheap substitute would be phosphoric acid or even cheaper muriatic (HCl) that has been diluted, if you have the neccesary protective equipment. Phosphoric doesnt fume but it can be hard to find.

    Muriatic acid.. serious etching and dissolution.

    Vinegar....for very gentle action.

    Phosphoric is easily available at Lowes etc if you look for 'concrete etch". Much of it is phosphoric.

    Great rust remover, and unlike muriatic, it will not spread rust all through your shop

    I've been using peletized acid that I believe is phosphoric to clean the screens in my well. Does anyone know if concrete etch would be a locally available substitute.

    That is a specialty version which contains, but may have other stuff besides, phosphoric. I think it is specifically a paint pre-treat, with extras.

    If you have a Dollar Tree near by they sell a product called "The Works Tub and Shower Cleaner" . The stuff works great. I use it on my boat to clean that scum and stains that get on fiberglass. It costs $1. a bottle. The hull cleaner at the boat store cost $10. The cheap stuff works just as good. You can smell some kind of acid in it.

    Dpmn't ever use muratic acid indoors. The fumes travel everywhere causing rust, lifting chrome, and inflicting general mischief in the most unespected places. The fumes even migrate through plastic jugs.

    Use phosphoiric acid for general etching and lime removal. If you have more time use acetic acid like white vinegar.

    Default Iron Out instead of Lime Away

    IMO hands down a product called "Iron Out" is the alternative to lime away. The odor is strong but the out come is good.
