Many appliances gain a coat of oily sludge near the range, microwave, and range hood if you pan fry foods in oil. Cleaning these areas with just a paper towel can result in left behind dust from the towels. Instead use a light coat of mineral oil on your paper towel before wiping off those areas — they will be cleaner than just using a dry towel alone.
This tip comes from household weblog The Manly Housekeeper who points out that mineral oil is the best to use as it won't turn rancid and gummy like vegetable oils can. This is also the reason why mineral oil is the best to use on cutting boards and wooden knife handles.
