Over time, several years in fact, the coating on my fridge/freezer, has, in places discoloured. It is not an overall discolouration, which would be OK. Is there a way to bring the white back to white?
Scrubbing Bubbles bathroom cleaner works pretty well. Lay some old towels or newspapers on the floor at the bottom of the appliance, spray it on and let it work, then wipe with a hot water wash cloth several times to rinse. If it comes out clean, you can use automotive wax to really make em shine.
Shhh!!( I used to do that when I smoked, but since I've been quit now for three years and the appliances are new, I don't have to do it anymore. Bought em with the money I saved on cigarettes)( Re-painted all the walls too, my wife is very happy that I quit)
I would try to use that arm and hammer magic eraser. That thing works miracles.
I use oxi clean and fantastik it works fine for me
