Thank you for viewing. For IH cooktops Silicone Gap guard Silicone gap guard to protect the gaps of IH cooktops. I opened it, but the size didn't fit, so I didn't use it and kept it stored at home in a bag. I think there are no noticeable stains, but it's a personal assessment and has been stored at home, so there may be oversights.
