Hidere all, I bought some canning jars at an auction to sell honey in, and the lady had stored them with the lid rings left on, which left some rust stains on the glass in the lid thread area. I tried lemon juice, vinegar, and a lot of elbow grease, but it will not come off. Any ideas out there? I just got an order for 12 pints, and I gotta deliver! Thanx muchly!
