Sorry about that redwards.
How'd your battery crack?
Time for an Optima?
At least the battery just cracked and didn't blow up...that sends acid everywhere.
Hi, X2 on the baking soda bath. Get it outside and rinse it off. Tray, chassis, everything. Keep doing it for a couple of days. Wear rubber gloves and a throw away shirt. Do not get it in your eyes. Battery acid is extremely corrosive on skin and metal. Keep kids and pets away. Be careful. Good luck
What kind of battery and what battery mounting do you have?
I seem to remember viniger first to etch off the acid, then the baking soda and a brush. Then some light grease.
