OOPS! The home version releases ACID as it cures. Pretty hard on boat hardware. Acetic acid, that is, vinegar. Not in a class with some other acids for corrosiveness, but not desirable. Won't normally do much to stainless. Casady Vinegar is greatly diluted acetic acid. Something around 5% acidity. Acetic acid can also be 20%, 50%,100%, or anything in between, all which might surprise you with their effects on metals including stainless. We are discussing silicone caulk. What is the concentration of the acid? Casady Don't know and don't care. Just pointing out that not all acetic acid is 5%. Of course not. The caulk is undoubtedly less than one tenth that. Casady |
