    Dunno why the color is that of rust, but, in alt.home.repair
    I posted a bunch of pictures where I removed real rust stains
    (from tools left outside all winter) on plastic outdoor tables
    with pool acid.

    The caveat was that I was removing real rust stains; and that
    the medium was plastic.

    In your case, who knows what the rust-colored stain really is;
    and, depending on what the paver is made out of, the pool acid
    may eat into the paver (so you must test in an inconspicuous
    area first).

    Someone else should know a lot more; but that's all I can offer
    without knowing what the rust-colored stain is made out of.

    Have you tried battery terminal cleaner sold at auto parts stores? You
    could try a small spray can of it before looking for a larger container
    from a battery warehouse. There is a Crown Battery commercial location
    on the other side of town from me and companies like that have very
    knowledgeable folks on their staff. o_O

    I'd try some CLR, first. Sulfamic acid (used as a tile and grout
    cleaner - in the tile section of the store), next.

    Found this site, but have not used the product. Just passing it
    along.

    Why/how is acid getting out of the batteries?

    I'm trying to figure out what sort of stains you actually have. Your
    description of being rust colored has gotten you suggestions on how to
    remove rust but I don't think that's what you have. Acids can induce iron
    to rust but they don't create it; the opposite in fact.

    My best guess is that the acid has dissolved some of the paver surface. If
    that's it, no cure.

    Maybe dissolve some more paver surface to even it out?

    That is my take too. I'm not sure calling it a stain is the
    right terminology. If you put acid on something it can react
    with, the chemical reaction turns what is there into something else
    and that portion is gone and not recoverable.



    >

    might be an option if the look of those "stained" areas
    is acceptable and the rest of the pavers is not a real large
    area. It's also possible that the acid removed a layer of
    old, faded paver and left the new exposed. In that case,
    power washing the rest might even it out.

    My thought too, but there is a cure.

    First wash with water. If that doesn't clear up the problem, get a
    paver puller and some replacement pavers. Done deal.

    Can't you just turn the paver over to the good side and use it again?

    Acid is used to intentionally do "acid staining" of concrete to change the
    color of the concrete. So, I doubt that anything will "reverse" the stains
    that you are causing on people's concrete or brick pavers.

    I like the ideas that others suggested of using a "paver puller" to remove
    the damaged pavers and either replace them or flip them over etc. Or, maybe
    switch them out with other pavers that are in a non-visible location.

    Obviously, something needs to be put down under where the work is being done
    so no acid or anything else drips down and damages the surface of whatever
    is underneath. That would be true for any type of on-sight vehicle repair
    service.

    Why a "major problem"? Do batteries in the UK not have corrosion? It
    is from the acid that can weep out of the cells.

    <http://www.agcoauto.com/content/images/electrical/transient/corroded_terminal.jpg>

    I've seen battery mounts and fasteners rusted, corroded, same with
    corrosion deep into a battery cable - that can not be cleaned up and
    needs replaced.

    Tip: put a copper penny on the battery top, the corrosion will migrate
    to the penny and not the cable. Replace as needed for a penny.

    Hence, the plastic battery boxes I mentioned prior.

    I haven't seen a battery as bad as that for years now.
    And never seen one so bad that acid leaks on to the floor.
    A bit of WD40 or similar on the terminals cuts out most of the terminal
    corrosion problems.

    Most batteries for traction applications are sealed in case the vehicle
    overturns when the driver could be burned otherwise.
