There is a lot of cooking that goes on in my apartment and that results in filthy drip pans. Over the past year they have gotten even more disgusting and sticky, despite me doing my best to clean them with baking soda, vinegar, and vigorous scrubbing.
I have heard that ammonia, which is apparently perfectly safe for the environment (but should not be inhaled), does a great job in tidying up the grime that settles in drip pans, so I have acquired some.
I went outside and placed each of the 4 drip pans into a gallon zip lock bag and poured about 1/4 cup of ammonia into the base and then I sealed the bags. I will visit my drip pans again in the morning after they have soaked for 24 hours.
I will update on this matter tomorrow.
UPDATE: So, the ammonia did not do what I thought it would; however, I believe that our drip pans might have been beyond repair. They were already rusting and we forgot food in them forty too many times. I have discovered that drip pans are rather inexpensive, so I think we will just replace these when our lease ends next year.
