If you want to keep your slippers in good shape, they're going to require delicate care. Most slippers should be spot cleaned and air dried unless instructions say differently. If you have to dry them quickly, a hairdryer on the lowest heat setting should do the trick. Refer to the manufacturer's care instructions as each slipper requires specific care. You may need a special cleaner for suede and leather, followed by brushing or using a soft cloth to remove any stains. If you're concerned about odor, sprinkle some baking soda into each shoe and let it sit for a few hours. The baking soda will deodorize the shoes in addition to soaking up excess dirt and oils. For shearling- or plush-lined slippers, avoid harsh soaps and detergents, as they can damage the material. If you experience any matting, use a shoe brush or a dry towel to comb through the knots. A vacuum hose may also lift away any dirt and debris from the shoes.
