"Even if you only wear something once, you deposit body oils, perspiration, perfume and dead skin cells, which provide plenty of food for insects," says Boorstein. Discourage moths from making a meal out of cashmere pieces by hand washing them in tepid water with baby shampoo and laying flat to air-dry. Then stow each sweater in a breathable muslin bag with cedar blocks to deter pests.
Restore shrunken wool with a technique called wet blocking. Soak the piece in warm water with detergent to relax tight-knit fibers, then roll in a thick towel to sop up moisture. Using the shape of a well-fitting sweater as your guide, lay the shrunken sweater on a flat surface and carefully stretch it out until you get the right proportions. Air-dry and check the shape every ten minutes.
When a pricey purse gets soaked in a rainstorm, stuff it with newspaper to absorb water and prevent the leather from warping and contorting, suggests Mesquita. Let the bag air-dry away from a heat source—which can over-dry the hide—and replace wet newspaper as needed. "Once dry, work in a leather conditioner to soften the skin," he says.
Sunglasses. Soften scratches on sunglasses by squirting a small amount of car wax onto a cotton ball and rubbing it on each lens in a circular motion. Remove excess product with a lint-free microfiber cloth—the kind that came with your shades—and repeat if necessary. "For allover shine, a mixture of one-part water, two-parts baking soda works best," says Whitney Moorman of Sunglass Warehouse.
