After soaking, lift one knob out and rub it with a soft cloth. In many cases, the greasy film will come off in a dull, slippery layer right away. Pay extra attention to the back, the ridges, and the little indicator line on the front, since grease loves to settle into those details.
If a bit remains in grooves or around the stem opening, use a soft toothbrush and 10 to 15 gentle strokes. You shouldn’t need to bear down. If you find yourself really scrubbing, put the knob back into the soapy water for another 10 minutes and try again.
8. My method for the greasy spots behind the knobs
Once the knobs are off, you’ll often see rings or streaks of grime on the stove face itself. Dip a cloth into the same warm, soapy water and wring it until it’s damp, not dripping. Wipe the area around each knob stem carefully. I like to fold the cloth over my fingertip to get close to the base without pushing water where it doesn’t belong.
