Cleaning burner pans - each burner pan sealed in a ziploc bag with just a splash of ammonia poured into each; let stand 24 hours; wipe dry; used a little paste of baking soda and hydrogen peroxide to rub off some last little bits of gunk that needed the tiniest bit of elbow grease to get off.
This Is The Easiest Way To Clean Your Stove Burners
Cleaning stove burner pans: Place each pan and burner in a large ziploc bag (one bag per item) add 1/4 cup ammonia to bag (no need to soak burner); close bag, leave outside on porch overnight. In the morning, simply rinse the gunk away! For extra stubborn stains, make a paste with baking soda and hydrogen peroxide & scrub.
