I have a wire oven shelf (rack) which has some burned-on grease:
The shelf is covered with chrome so I cannot put it in my oven when going through the pyrolysis cycle (apparently there would be toxic fumes) and normal washing does not help.
I noticed that the stains can be scraped with a knife so I was wondering whether I could go ahead with a metal brush. I feel that this would endanger the chrome coating. I do not care that much about the coating itself, aesthetically-speaking, but rather for its protective and somehow anti-adhesive properties.
Is there a standard way to clean such shelves?
