Line drying clothes or reducing drying time is a great way to eliminate static cling. Another option is to dry clothes with dryer sheets. Dryer sheets have an antistatic coating.
Throwing a ball of aluminum foil in the dryer is another way to remove static because it discharges the fabric. Static cling occurs when two different fabrics rub together while drying. The two fabrics exchange electrons, which creates an electrical charge. The charge builds up and causes the fabrics to cling to each other. Static cling is worse in dry areas and during the winter because moist air has water vapors that discharge fabric.
