That's the right thing to do, but you have to use enough water to allow it to 
soak into every place where acid might have gotten. Excess water is no 
problem. Excess soda is no problem. Excess acid IS a problem.

You're done when wiping it up with a damp sponge and applying more 
water/soda mix doesn't cause any more bubbling. Then wipe up with a damp 
sponge, add just water, and wipe up again. Rinse and repeat. Let dry.

I would treat the area with LPS-3 to prevent further rust, but it needs to be 
completely dry first.

The battery caps are ultrasonically welded to the body. Something went 
wrong here, and that's rare. It's a mature technology.
