Neutralize Battery Acid
I have a couple cups of battery acid left over after buying a battery for my lawnmower.
What's the best way to neutralize this stuff so I can pour it down the toilet?
Seems to me I used baking soda years ago but that made quite a bubbly mess.

I pour it on weeds in my gravel yard...must be limestone cause it sure does bubble!
A big box of baking soda would probably work...but why not check at a battery or repair shop?

It's sulphuric acid, and it will bubble when it touches something organic, or steel for that matter. Pouring it down the toilet would be a no no. Even if it cost you a couple of bucks, take it to Wal Mart or some other auto parts place and let them recycle it.

Why not just store it safely, in case you need some more later.

After reading this:
Concentrated sulfuric acid is frequently the major ingredient in acidic drain cleaners which are used to remove grease, hair, tissue paper, etc.
