Have a golf cart business that leaves sulfuric acid stains on brick pavers
after batteries have been charged. It has the appearence of the color of rust.
Customers are complaining about the stains on their pavers. Any soulution to
remove these stains would be appreciated.

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
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.
What have you tried so far?
Is it possible to liberate some old used carpeting from the dumpster of
any carpet retailer in your area and park the golf cart over scrap
pieces of carpet before recharging their batteries?
If it wuz me, I'd probably try hydrochloric acid since the only thing
reddish brown I know of is iron oxide, and hydrochloric acid will
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
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.

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.
If you have battery acid leaking then you have a major problem with the
This needs attention or your golf carts will corrode away apart from the
safety aspect (someone could get an acid burn).
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
Most batteries for traction applications are sealed in case the vehicle
overturns when the driver could be burned otherwise.
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
