Run the self-cleaning cycle today and wipe off the door as needed. Remove plastic knobs to be sure the heat won't warp them. If you have a non-self-cleaning oven, use an oven cleaner, a stiff brush and thick gloves. Never use abrasives and above all, be sure to open a window.
Winter's muddy feet and road salts wreak havoc on the family car, which is probably also home to stray mittens and who knows what else by now. Besides washing it this week, make time for a thorough clean-out and detailing, including shampooing the floor mats.
