I've used the purple degreaser to remove years of grease buildup from a
Hobart mixer, and buildup on baking sheets and waffle irons. The purple
stuff is lye based and will dissolve bodies if the need arises.

That is the best recommendation I've ever seen!

OK, Purple cleaner and Oven cleaner are next to try.

Thanks!
