I finally found that can of spray cleaner for battery terminals and the battery case itself. It's called Battery Cleaner and Acid Detector. I bought it in Walmart. It foams up on the terminal and battery case and will immediately turn pink if it comes in contact with any acid or corrosion. Just wipe it off with a wet towel and all trace of acid on a battery case is gone. All white corrosion on terminals is gone!

A great product at a great price!
