Use Hydrogen Peroxide to Clean the Refrigerator
If the seal is still grungy or has stains from food and mold growth, then a good dousing of a common household cleaner can spiff up the dingy refrigerator door gasket. Using the effective antibacterial hydrogen peroxide to clean the refrigerator is an easy, affordable, and safe choice. It easily removes stains and can be combined with mild dishwashing liquid for an even more effective stain and odor remover.
