If you were going to spend your money, maybe these aren't the highest bang for the buck. I thought it was a nice color with the pushbutton panel metal stamped(?) design, vs. a plain-Jane stainless panel. Very 50'ish.
Anyways -not selling, just sayin' And yes, it needs cleaning.
Well hopefully whoever gets the stove will have the sense to mount the control panel next to the stove in the wall instead of directly behind it to eliminate that possible hazard.
