I love the cooking and features on this stove but the bummer caps do not stay clean! If you get anything on the caps you are REQUIRED to clean them after use or you will have an ever lasting stain on them. Honestly this stove is amazing but material selection of the bummer caps is extremely flawed. I’ve cleaned with soap and water per users manual useless, tried baking soda and vinegar useless. I am so disappointed to have a beautiful stove with horrible looking caps.
