I'll try it but I don't think it will work.. I've literally tried everything I can think of even dish soap wiping with newspaper, paper towels, microfibre towel... I'll give it a try though.Run down to Home Depot and spend about $2.50 on some BarKeepers' Friend in the liquid silver bottle. Betcha that gets it off! No scratching, either.
Water spots disappear, too. I didn't believe it, until I saw it for $2.38 + tax. Worked! Worked, really well! Made a believer outta me!
