I was so happy to find this product on line! As its name implies, the Instant Copper Polish starts working in an "instant" and makes my copper items look just like I want them to look - bright, shiny, copper-pink, and beautiful -- with very little effort. I have a set of copper-clad RevereWare pans that I purchased 40 years ago when I moved to my first home away from home. This polish makes them look brand new and worthy of display. I have purchased additional RevereWare pieces from auctions to add to my foundation set that had obviously received little to no care -- and this polish has removed decades of burned-on grease and even plastic with some elbow grease and determination. Other copper cleansers I tried on these auction pieces didn't phase the stains on the copper. This product works for me on my all copper items and also with the interior stainless steel of the cookware! LOVE this instant polish! Thank you so much!
