This might be a stupid question, but would Baking Soda work for this? I
used to work as an Electrician, and had to deal with an UPS that used lead
acid batteries, we always used Baking Soda to neutralize the acid. Maybe
I'm totally off center on this one, wouldn't surprise me.
In any case where can one find Muriatic Acid? It's not one of the Acid's
I've heard of.
