Well, I gave the coke a chance. I'll need to wait a little while to see if it takes care of the residual acid. If it doesn't, I'll give the baking soda and water a try.
How much baking soda vs how much water? Do you just want a paste? Or do you want it more of a liquid consistancy to put on the affected parts?
