If you have a GE stove and dishwasher that are only about 6 years old, but the fronts are impossible to clean. After only about 2 years a kind of greasy heavy film developed on the oven and dishwasher door (outside). I've tried regular lyson kitchen cleaner, 409, scrubbing bubbles, and orange glo (which made it much worse).
You can clean them with mix murphys oil soap and ammonia into warm water.
Or..
Have you tried the Mr. Clean magic eraser. I use it on my fridge all the time. There is a slight texture on the fridge that seems to trap dirt and cleaning solutions. I've used the eraser and it cleans very good. If the grease build up on the oven door is on the glass part of it, use an SOS pad very lightly. It will cut through the grease. Depending on the finish on the dishwasher you may want to try an SOS pad, again very lightly to cut through the grease. There is also another product called Simple Green that cuts through all types of grease. They sell it at Wal-Mart and Sam's Club. My husband used it to clean grease on the floor of the garage. It does have a very strong odor to it , but is not harmful in anyway. Good Luck
