I have 8 regular Ball canning jars that held candles. Bought them in a store. The metal wick thing is very tough to get out of the bottom and the paper label left residue on the outside bottom and front.
I boiled them for 7 minutes and they aren't clean looking.
Any advice? I was told to either try a weak bleach solution or GOOP.
Planning to do a huge batch this weekend and need the jars!!!
