Things You'll Need
Line-dried clothing and socks tend to feel hard or rough. Prevent this by removing the socks from the line before they are completely dried and finish drying them in the dryer.
Even the dirtiest socks should come out soft from the washing machine and dryer. Hard, crusty socks occur when either the soil isn't completely removed during laundering or when hard water causes a buildup in the fabric's fibers. Hard socks aren't pleasant to wear, especially if they retained dirt and odor after washing. Getting the socks clean and preventing any hard water residue ensures your socks will stay soft and comfortable after a thorough washing.

Unfold the the socks before placing them in the washing machine. The top of each sock tends to roll under when taken off. Folded and rolled socks can't come completely clean during washing, which can result in a hard texture.
Place the socks in the washer, taking care not to overfill the wash tub with too much clothing. Over-filled tubs can't agitate and clean the clothing properly.
Set the washer on the normal cycle. Use warm or hot water.
Add the detergent to the wash tub after it fills with water. Then add 1/4 cup baking soda to the water. The soda helps break down any soil that could cause hardening in the socks and clothing.
Open the machine before the final rinse cycle. Add 1/2 cup of plain white vinegar to the rinse water. The vinegar ensures all detergent and any hard water residue is removed from the socks.
Place the freshly washed socks into the dryer, and tumble dry. Add a fabric softener sheet to further ensure the socks don't become hard. Or hang them on a line and air-dry, if you prefer, although they won't get as soft with this drying method.
