How to Wash Waterproof Socks? | Care That Keeps Them Dry

Guide / By

Waterproof socks require gentle washing by hand or machine on cold with a mild detergent, followed by air drying away from heat, to protect their waterproof membrane.

Pay good money for waterproof socks and the last thing you want is to wreck the membrane in a single hot wash cycle. The care is different from regular socks because the waterproof layer is delicate. Treat them right, though, and a quality pair lasts for years of wet hikes and chilly commutes. The short version is cold water, gentle soap, no heat drying. Here is the exact routine that keeps the waterproofing working.

What Makes Washing Waterproof Socks Different?

Ordinary socks can take hot water, bleach, and a tumble dryer without issue. Waterproof socks cannot, because they rely on a bonded membrane or laminated layer that heat and harsh chemicals degrade. The rule: if it is aggressive enough to strip oil from your hands, it is harsh enough to delaminate a sock membrane. Fabric softener is a particular enemy because it coats the membrane’s pores and kills breathability.

How to Wash Waterproof Socks by Hand

Hand washing is the gentlest route and the one most manufacturers recommend first, including DexShell, whose official instructions specify a maximum temperature of 30°C (86°F) and a mild process.

  • Turn the socks inside out to release trapped dirt and debris from the interior.
  • Fill a sink or basin with cold or lukewarm water and add a small squirt of mild detergent — a gentle gear cleaner works well, but a normal liquid laundry detergent without additives is fine.
  • Submerge the socks and let them soak for 5–10 minutes if they are visibly dirty. Gently agitate with your hands; rub the fabric lightly but never scrub hard or wring it out.
  • Rinse thoroughly in clean water until no soap remains. Squeeze the water out gently — do not twist or wring the fabric, which can stress the membrane.

Can You Machine Wash Waterproof Socks?

Yes, but with precautions. Use a gentle or delicate cycle with cold water and a mild detergent. Place the socks inside a mesh laundry bag to reduce abrasion against the drum or other clothing. Skip the spin cycle at the end if your machine allows a “no spin” option; if not, the gentle spin is acceptable. Do not use fabric softener, bleach, or stain removers.

How to Dry Waterproof Socks

Air drying is the only safe method. Lay the socks flat on a drying rack or hang them by the toe in a ventilated area, away from radiators, direct sunlight, and heat vents. Heat from a tumble dryer, iron, or radiator will degrade the waterproofing over repeated cycles. Do not wring or twist them before drying, and never iron them — waterproof fabric and an iron do not mix.

Common Mistakes That Damage Waterproof Socks

The most frequent wash errors come from treating waterproof socks like regular ones. Hot water, high-heat wash settings, and tumble drying are the top three membrane killers. Fabric softener and bleach are close behind. Skipping the care label is another — if the brand’s instructions conflict with generic advice, follow the label.

FAQs

Can I use regular laundry detergent on waterproof socks?

Yes, as long as it is a mild liquid detergent without bleach or fabric softener. Avoid powder detergents with brighteners and any “sport” formula that contains enzyme additives — plain fragrance-free liquid is safest.

How often should I wash waterproof socks?

Wash them when they are visibly dirty or start to smell. Many users rinse them with cold water after each use and do a full wash only every 5–10 wears, which extends the membrane’s lifespan substantially.

Do waterproof socks lose their waterproofing over time?

All waterproof socks eventually lose effectiveness after repeated washing and wear, but proper care dramatically slows the decline. A pair washed correctly often lasts two to three seasons before the membrane begins to leak around the seams.
