Having never used any acid stronger than vinegar on my bottles, I was wondering how strong a solution of muriatic acid is safe to use, without etching or otherwise harming the glass. Thanks John
Muriatic acid is one of the best acids to clean bottles with. Whatever you do though, don't use it inside!!! It will corrode all of your pipes and anything metal in your house.
That is interesting Buzzkutt/Jim, so with your method you basically confine the HCl vapors and let the acidic atmosphere in the bucket react with the deposits on and in the bottles?
I've always diluted it to 1/4th to 1/8th in water and submerged the stuff to be cleaned, but if your method works better I will have to try it out. I have about 35 gallons of glass sitting that needs acid treatment so at that scale maximum efficiency/minimum waste is important.
