i get rather anal when i do mine. i litterally disassemble them. i take either sand paper or steel wool to the triangle rack. steel wool to about everything else. i would take off the top vent and reinstall with ss hardware. not sure of the onetouch system but they are not that expensive. new food rack, make sure you get the flip up type. the legs i polish up with 0000 steel wool. the body with steel wool also. if its grey , its grey. i would just get a rubber leg tips for the end of the front leg. either buy new grey plastic handles or make yer own to keep prices low.
