I bought some zinc canning lids on Ebay and wanted to clean them. I looked about to find the easiest way to spiff them up a bit. I washed the lid thoroughly and then used lemon juice (I had a bottle of it) with a scroungy type pad that had pretty much gone soft. I think it's doing a pretty good job on them. Two down......ten to go! :)
The cleaned two are on the left the uncleaned ones on the right. It was hard to get a good photo of how well they cleaned up but they really look nice. I won't be using these to actually can with but wanted zinc ones to put on some blue ball jars that will be coming here soon from my Mom's estate. I love using old canning jars to store my dry goods in.
