How to Wash Compression Socks | Keep the Squeeze

Your compression socks work only as long as the knit keeps its tension, and washing is where most pairs lose it fast. Hot water, fabric softener, and dryer heat break down the elastic fibers that create the graduated pressure your legs depend on. The right routine takes about five minutes and keeps a pair working for months longer than a careless one.

The Short Wash Cycle That Works

Compression therapy brands agree on the basics: mild detergent, cool or lukewarm water, gentle handling, and no heat in the dryer. Sigvaris recommends hand washing in lukewarm water, while medi suggests washing at 30 or 40 degrees Celsius — roughly 86 to 104 degrees Fahrenheit. Both brands stress the same point: never wring, twist, or stretch the fabric while it’s wet.

Here’s the hand-wash method that satisfies every brand’s instructions:

• Fill a sink or basin with cool or lukewarm water — never hot.
• Add a small amount of mild detergent and swish to dissolve it.
• Soak the socks briefly, then gently rub the fabric with your hands, paying attention to the heel, toe, foot, seams, and any band areas.
• Rinse until the water runs completely clear with no soap residue.
• Press the water out gently — don’t wring — then roll the socks in a towel and press to absorb remaining moisture.
• Lay them flat on a drying rack or counter, out of direct sunlight and away from radiators.

Machine washing is fine when your brand allows it: turn the socks inside out, drop them in a mesh laundry bag, and run a delicate or gentle cycle with cold or cool water. Skip fabric softener entirely — it coats the fibers and reduces compression.

Silicone Bands Need Special Care

Many compression socks include a silicone or rubber grip band at the top to keep them from sliding down. That band collects dead skin cells and body oils with every wear, which reduces its grip over time. Wipe the band area periodically with an alcohol wipe to remove the buildup and restore traction. Keep the alcohol away from the knit fabric itself, since it can dry out the fibers.

What Shortens Compression Sock Life

The most common mistakes all involve heat, harsh chemicals, or rough handling. Hot water and dryer heat are the fastest way to break down elastic. Fabric softener and bleach coat or eat away at the fibers, reducing both compression and durability. Wringing or twisting wet socks stretches the knit unevenly, and hanging them by the cuffs pulls the band out of shape.

Overloading the washer is another quiet killer — socks bump against other heavy items, which agitates the fabric more aggressively than the delicate cycle intends. Skip the rinse cycle shortcut too; leftover detergent irritates skin and attracts dirt faster. If your socks still feel tight or show visible wear on the knit, Ortho Health’s care guide for medical compression stockings explains why proper washing directly affects how long the garment delivers its rated pressure.

The single best rule: read the care label on your specific pair and follow it over any general advice. Different brands and even different product lines within a brand use different materials, and medi’s care instructions confirm that cleaning methods can change elasticity, fit, and pressure delivery. When your label conflicts with general guidance, the label wins — your socks are medical garments, and the manufacturer knows exactly what their knit can handle.
