I find the best way to remove any baked on or burned residue in pans or casseroles, or burner rings is to sprinkle on some dry dishwasher detergent, cover with hot tap water and allow to sit overnight. In the AM, the stuff will come off with a wipe of the sponge. I don't find that any other method that works without scrubbing.

As we’ve , I can obtain borax for $2.89 for a box that contains six cups, washing soda for $1.89 for a box that contains six cups, and water is basically free (a tiny fraction of a cent for six cups). If you mix these together, you get 12 cups of dry dishwashing detergent for $4.78 (or 18 cups of liquid), about I make my own lye soap…could you use a bar of castille lye soap with your laundry and dishwashing detergents? I made a liquid version and it did not gel like other soaps do….since bar soap is just detergent in bar form! It is quite halarious what companies do…sell you the same product with different names and in different departments! lol!.40 per cup of dry detergent.
