I cleaned my oven today, i.e., turned it to “clean” for about four hours, and then washed out the inside with plain water.
However, around the sides of the door are a great deal of greasy(?) marks. Last time I did this, I cleaned them off with formula 409, but they returned almost instantly, and within a couple of weeks, had migrated inside the oven.
What should I use to clean them off once and for all?
