Email.... work... yadda.... While battery leakage is basic (alkaline) and needs an acid (vinegar) to neutralize, the leakage from AE capacitors is typically acidic (boric acid is used in the formula to "self-heal" the aluminum plates) and so should be neutralized with a base. I've seen recommendations to use: - baking-soda and water - deionized water - ammonia - detergent to clean up after AE caps. The key seems to be having a polar solvent. The only things I've ever used myself are detergent/water and IPA to clean up afterwards. And, yeah - it gets under the solder mask, under mounted components, into connectors, etc. All nasty stuff. Good luck. -Josh
