Glue?

While important to get it out long term (and it could be an issue for a large glob of silicone thst is only cured on the outside and slowly leaches out a small constant stream of acetic acid), the vinegar we soak in to clean corroded boards in is acetic acid. Is it the acid itself or the acid in conjunction with something else? I know there was the old prohibition about using acid-core flux solder on electronics (and the acid flux is, I’m fairly certain, a weak organic avid similar to vinegar). Copper alone should not be that vulnerable but some of the boards may use cheaper alloys that are more acid sensitive. But the issue is still there wrt the vinegar bath.-kby

Some silicones release acetic acid when they cure, which can corrode copper. Newer silicones which release ethanol while curing should not be a problem. If in doubt, check for a vinegar odor before using.
