Refrigerator - Care and Cleaning of Interior and Gasket
If you need to clean or remove mildew or mold from the interior or gasket of your refrigerator, freezer, or standalone icemaker, wipe with a mixture of 1 quart warm water and 1 tablespoon of baking soda. Rinse the gasket thoroughly and wipe dry with a clean cloth. This both cleans the gasket and neutralizes odors.
Do not clean with any products containing petroleum distillates, detergent, bleach or ammonia as they may damage your refrigerator. Also, do not clean plastic parts from your refrigerator in your dishwasher.
