My wine glasses can look a little dingy and tinted from time to time. After making a Mexican dish the other night, I had the lime rind left over. The glasses were right in the sink and I thought: "if lemons can clean virtually anything, I bet these limes can do the same thing." I'm pleased to report as soon as the citric acid hit the glass the built-up wine came clean. I moved onto my coffee pot and some tervis tumblers that my husband drinks tea from. Give it a try, it only takes a few minutes and your kitchen will sparkle.
You gotta love a homemade remedy.
