I absolutely love this sponge. I burnt food in my stunning le creuset saucepan. I boiled water with lemon and soda, used different sponges (not metallic). To my surprise, this sponge removed the black spots very quickly (added only water, no any chemicals used), no black spot left at all! Highly recommend.
Love these pads. The best is that they won’t scratch anything, even glass.
Great scrubbers. Love that you can throw them in the dishwasher to clean. Bought them for friends to share the experience.
