Here you go!
Crumple the foil into a ball and get it wet. Sprinkle with baking soda and scrub the racks.
just crumple in ball and use metal to metal and rub; steel wool works well too or SOS, BRILLO pads , wire grill brush
Hi Drj: I've never had good luck using aluminum foil:( I use a paste of cream of tartar (the dry stuff) and vinegar. Just put it on the gunk, let it sit for about 15 seconds and wipe it off. You can use your aluminum foil if you'd like, or a Brillo pad:) Good luck.
