It’s easy if you just nuke a few wet paper towels for about a minute, then leave them sit for another 5 minutes. When your oven is off and all the way cool, soak paper towels in vinegar and lay them across the racks, over the glass door, and bottom. Basically, cover every surface with wet paper towels. Just spray each one one a paper towel, then use the towel to wipe your switches. If you use a paper towel instead of a rag, the cleanup is a snap, tooI’m definitely going to employ some of these today!
