The household cleaners with "citrus" seem to do well with grease on enamel, though some leave the SS a bit streaky.
I am big fan of the dry powdered "Soilax/SoilMax" product sold in hardware stores. If is designed to be mixed with water and used to clean walls before painting. I typically mix some up and put it in a spray bottle. It leaves no residue. This is similar to the product called Dirtex, which comes from the company that makes the TriSodiumPhosphate substiute product, but that seems to have some ammonia in it and it does not keep well in the DIY spray bottle.
