The side rubber (gasket) of my refrigerator is turning black. How can I clean it? I used vinegar and lemon, but it's not effective.
Consider using rubbing alcohol? Cheap & effective solvent in my experience. Perhaps apply & scrub with an old toothbrush? If still stained with grime, possibly try OTCounter cleaning products: 1) is those ‘magic eraser’ products that work like a chemical sponge when dampened. 2)try SOS pads, those abrasive/soapy blue scrubbing products?
Perhaps reframe/rationalize: acceptance. In the end little or no harm, how much effort does this dirty gasket warrant? Best of luck!
