You sort your clothes for washing; you should do the same for drying, so you’re not mixing slow- and quick-drying items. And wash your hands after transferring loads to the dryer. “People assume washed clothes are germ-free,” says Sandra Phillips, a cleaning consultant and the author of A Clean Break (Live-Right Books, $10, amazon.com). “But the dryer helps kill even more germs.”

Button-Down Shirts

Unfasten all buttons, including the tiny ones at the collar, before laundering. Otherwise, the agitation in the machine and the weight of other garments may cause buttonholes to tear. It’s a good idea to pretreat collars every time you wash them. “Once stains from body oils build up, they are very difficult to remove,” says Chris Allsbrooks, a textile analyst at the Drycleaning & Laundry Institute, in Laurel, Maryland. Use a stain remover (see Essential Laundry Products), or spot-clean with a mixture of water and liquid detergent. Pour it over the area, then rub with a soft toothbrush. It’s especially important to spot-clean permanent-press shirts and other items that have been treated with resins so they retain their shape, because these fabrics tend to hold soiling. Wash permanent-press shirts with all-purpose detergent on the permanent-press setting, which is gentler than the regular one, uses warm or hot water, and has a long cool-down rinse to further minimize wrinkling. Opt for the dryer’s permanent-press feature, which has a cool-down period at the end. Wash non-permanent-press shirts on the regular cycle in cold or warm water.

Hats and Gloves

Wash knit hats and gloves like sweaters. Spot-clean structured hats, like newsboy and baseball caps, which could become misshapen. You can hand wash gloves with small sections of leather if the leather is the same color as the knit; otherwise bleeding may be a problem. To dry, insert the handle of a wooden spoon in one finger and set the spoon end in a vase. This will help the glove retain its shape.
