Cooking oil splatter?

treat with dawn dishwashing liquid (preferrably the concentrated), let sit overnight, and then launder on hot. Works even on old stains or stains that have been through the dryer. :)

First thing to do is purchase a round screen to put on top of you skillet for less splatting. You can purchase these in most stores. I purchased mine at the grocery store. It really helps with all the splatting. You should be able to purchase on at most kitchen departments.

Try some kind of spot remover to get rid of the stains. Cooking oil is pretty difficult to get rid of. Give a spot remover a try.

next time you make beans, just add it for seasoning

just wash it its not that tough to get out :)

hope this helped
