Kuhn Rikon Flexible Silicone Stay-Clean Scrubber 1 "No good at all" Mrs Susan Halpern 12 September 2018 I think it said 'Best seller' in the shop. I can't understand why. I was very disappointed. It looked so nice, I couldn't wait to get home to try it out! But it doesn't clean pots well. Brown stains in an empty cup of tea didn't come off, so I went back to my ordinary washup sponge, and that removed the staining in a flash. I tried this product on a few other things, but it seemed useless. I got fed up looking at it and threw it away. A waste of money, and it wasn't cheap. I regret now throwing it away and wish I had just returned it to the shop with a complaint. A note from the team Thank you for placing your review. I'm sorry to hear this product hasn't worked well for you. I find our magic eraser stain remover blocks product reference 26032 are excellent for removing tea stains. Thanks again for your feedback.
