Range door bottom trim got rusty: a lousy design by GE.

I used a screwdriver and pliers. A nut driver would have been helpful. Oven door is removeable for cleaning and maintenance, but it's heavy and awkward. It has to be laid face-side down to disassemble, so have a protected tabletop ready to avoid scratches. Side trim pieces have to come off to get access to bottom trim mounting screws.
