Place your socks flat on an ironing board or covered table. Go over the top and underside of each sock with a lint roller to collect any loose turf particles.
Brush the top and underside of each sock vigorously with a firm, bristled brush. As you brush, the static electricity will help loosened particles cling to the brush.
Locate each remaining turf particle in the socks and pry them out with a pair of tweezers. Work carefully to avoid ripping any nylon threads loose.
Dampen a sponge with rubbing alcohol and dab any areas of the sock that have been stained green. The alcohol will help lift any stains without damaging the nylon. Allow it to penetrate the fabric for two to three minutes. Rinse each sock with cold water.
Rub in a small amount of liquid laundry detergent on the stained area and allow it to penetrate for five to 10 minutes. Rinse the socks with cold water and allow them to air-dry.
