Recently (and unbeknownst to me for over a week) my son bought my daughter a new battery for her car. Lacking the tools to do an immediate install, he placed the battery on her back seat. He (and she) forgot about it for several days and upon remembering, found the battery had leaked acid all over her back seat. She has been driving now a couple weeks with this acid in the cloth seats and on several occasions, forgetting it is there, has placed several items of clothing on top of the spot only to find holes in them later. How can I neatralize this? Or will I need to find a new back seat?
