How often should you wash your socks?

How much you wash your socks depends on a few factors, including how long you wear them, what activities you do, and how much your feet sweat. If you have extremely sweaty feet from hyperhidrosis, wash your socks after every wear. Washing your socks regularly helps them last longer, stay cleaner, and it’s better for your foot health.

Washing Machine vs Washing by Hand

The easiest way to wash your socks is in a washing machine whether you are washing floral FLAT SOCKS or your cotton crew socks. You can toss them in with all your other clothes and leave the rest to the machine.

Socks made of more delicate fabrics like cashmere, Merino wool or sheer tights should be handwashed to preserve quality and keep them from falling apart. Here is a step-by-step guide to how to wash socks using both methods:

How to Wash Socks in a Washing Machine

1. Separate your socks. What happens when a white shirt pairs with a red sock? It blushes. Separate socks by color or material and wash appropriately.
2. Turn them inside out. You should wash regular socks inside out to clean the inside of germs and bacteria plus prevent lint build up.
3. Use a mesh laundry bag. A mesh garment bag keeps your socks together, so you won’t lose them. FLAT SOCKS clean best when laundered in a mesh bag.
4. Wash socks on a cool or warm cycle with mild detergent. Cooler temperatures keep your socks looking like new, so they won’t fade or shrink. Mild detergent is enough to get most socks clean.
5. Tumble dry low. Using a lower heat to dry socks maintains their quality. Socks must be completely dry before wearing them or putting them away.

How To Wash Socks by Hand

1. Fill a sink with cool water and some mild detergent. Handwashing socks, like wool socks, in cold water helps them last longer and look newer.
2. Turn the socks inside out. You should turn socks inside out when washing to get a complete clean.
3. Soak for 5 to 10 minutes and agitate by hand. Soak dirtier socks for longer, and gently swish them around with your hands to loosen dirt.
4. Rinse thoroughly with cold, running water. Rinse your socks until all the suds are gone. Avoid twisting or ringing them out afterwards.
5. Air dry or hang to dry. Hang your hand washed socks on a wash line with clothes pins or lie them flat on a towel that you can wrap up to soak up moisture.

Washing Socks by Material

How to Clean White Socks

Renew your dingy, stained pairs of white socks with a few simple tricks. Depending on the material, normal white socks can be washed in warm or hot water with other whites. You can get rid of stains on socks by:

  • Adding a capful of non-chlorine bleach. WARNING: Never use bleach with your FLAT SOCKS. They clean up fine without it!
  • Using 1 cup of lemon juice and 2 tablespoons of powdered dishwasher detergent. Add to your regular laundry soap to brighten up white socks.

Getting the Smell Out of Socks

Want to free yourself from the embarrassment of smelly socks and shoes? FLAT SOCKS have odor-controlling tech that absorbs stink, keeping your shoes and feet smelling fresh. You can wear them alone or with socks for complete odor protection.

Another trick? Sprinkling baking soda into your detergent helps get rid of bad smells and brighten laundry. It’s a natural antibacterial that is gentle on delicate fabrics, too.
