Excellent Results Cleaning Burner Liners! (:
Awhile back, a couple people posted about soaking oven racks in ammonia overnight to eliminate all the hard work that goes into cleaning them. Well, I tried the same method to clean stainless burner liners yesterday with EXCELLENT results.
What I did, since ammonia fumes are so strong, is to place the burner liners in a glass mixing bowl, poured in enough ammonia to cover them, then covered the mixing bowl with a piece of plastic cling wrap. Left for about 24 hours, took them out, ran water over them and lightly swiped them off with a plastic-bristle brush and they look like brand new!
