Wash compression socks by hand in cool water with mild detergent, then air dry flat — this method preserves the elastic fibers that create the graduated compression therapy effect.
Compression socks are medical-grade garments, not regular socks. A single washing mistake — hot water, bleach, or the dryer — can permanently ruin the precisely engineered pressure gradient they provide. The right care routine takes under ten minutes and keeps them effective for months longer. Here is the exact protocol, brand by brand.
Why Hand Washing Is The Gold Standard For Compression Socks
Hand washing is gentler on the elastic fibers (spandex, elastane, or rubber) that create compression. Machine agitation — even on delicate cycles — accelerates fiber fatigue. Crazy Compression, Sigvaris, and Sockwell all list hand washing as their primary recommendation. The process is simple: cool or lukewarm water, mild detergent, five to thirty minutes of soaking, gentle rubbing at the bands and seams, and a thorough cool-water rinse. Never wring or twist the fabric — press it between towels to remove excess moisture, then air dry flat away from direct sunlight or radiators.
How To Machine Wash Compression Socks Without Ruining Them
Machine washing is acceptable when you follow three non-negotiable rules. First, turn the socks inside out (Sigvaris and Sockwell both specify this). Second, place them in a mesh laundry bag — Dr. Woof and Medi require it to prevent snags and excess agitation. Third, run only the gentle or delicate cycle with cold water. Air dry immediately afterward — do not let them sit damp in the machine.
What Temperature Water Should You Use?
Cold or lukewarm water only. Hot water weakens elastic fibers and causes irreversible loss of compression pressure. Crazy Compression specifies cool or warm but explicitly warns against hot. If your tap water feels warm to the touch but not hot, it is safe. If it steams or stings, it is too hot.
Which Detergent Is Safe For Compression Fabrics?
Use a mild, simple detergent without brighteners, softeners, or bleach. Fabric softeners coat the elastic fibers with a waxy residue that reduces their ability to grip and compress. Bleach chemically degrades spandex. Sigvaris sells its own washing solution, but any dye-free, fragrance-free “free and clear” detergent works. Never use stain removers, OxiClean-type boosters, or laundry pods with built-in softeners.
How To Dry Compression Socks — The One Brand Exception
Air drying flat is the universal rule — unless you own Medi compression stockings. Medi explicitly permits low-heat tumble drying, though it still recommends air drying for longest garment life. Every other brand in this guide forbids the dryer: The safe default is air dry flat, out of direct sun and away from heaters.
Compression Sock Care By Brand — Quick Reference
| Brand | Wash Method | Drying Rule |
|---|---|---|
| Crazy Compression | Hand wash cool/warm, mild detergent, soak 5–30 min | Air dry flat — never machine dry |
| Medi | Machine wash 30–40°C, gentle cycle, mesh bag required, max 1,200 RPM | Low-heat tumble dry OK; air dry recommended |
| Sigvaris | Hand wash recommended; machine wash inside out in mesh bag | Air dry — avoid tumble drying |
| Sockwell | Inside out, warm/cold water, mild detergent | Air dry best; low heat acceptable if needed |
| Dr. Woof | Machine wash cold, gentle cycle, mesh bag mandatory | Air dry only |
The Three Mistakes That Ruin Compression Socks Fastest
Heat damage is the most common failure — hot water or a hot dryer weakens elastic fibers permanently. Chemical damage is second: bleach and fabric softeners break down the compression material and reduce pressure application. Physical damage is third: wringing, twisting, or stretching the wet fabric distorts the graduated fit. The fix for all three is simple: cool water, mild detergent, no wringing, air dry.

How Often Should You Wash Compression Socks?
Medi recommends washing compression stockings every evening after taking them off. Daily washing removes skin oils, sweat, and debris that degrade the fabric over time. If you wear them only occasionally, wash after each wear. Never let a dirty pair sit for days — body oils accelerate elastic breakdown and create odor that is hard to remove later.
Special Care: Silicone Bands And Crystal Motifs
Compression socks with silicone grip bands at the top need extra attention. BioPed Footcare recommends cleaning silicone bands with an alcohol wipe in a circular motion to remove skin debris and restore grip. Do not use soap on silicone — it leaves a residue that reduces friction. For stockings with crystal motifs or decorative elements, Medi says to turn them inside out and place them in a laundry net before washing to prevent snagging or damage.
Final Compression Sock Care Checklist
- Turn socks inside out before washing (Sigvaris, Sockwell, Medi).
- Place in a mesh laundry bag if machine washing (Crazy Compression, Dr. Woof, Medi).
- Use cold or lukewarm water only — hot water ruins elasticity.
- Choose mild detergent without bleach, softeners, or brighteners.
- Wash by hand when possible; machine wash only on gentle/delicate cycle.
- Do not wring or twist — press water into a towel instead.
- Air dry flat away from sun, radiators, and heaters (Medi is the sole exception for low-heat drying).
- Clean silicone bands with alcohol wipes, not soap.
FAQs
Can you put compression socks in the dryer?
Most brands say no — heat destroys the elastic fibers. Medi is the only major brand that explicitly allows low-heat tumble drying, though air drying is still recommended for longest life. If you are not sure which brand you own, air dry flat to be safe.
What happens if you wash compression socks in hot water?
Hot water permanently weakens the spandex and rubber fibers that create the graduated pressure. The socks lose their compression efficacy and may become loose or baggy. Always use cold or lukewarm water — if the tap feels hot to the touch, it is too hot.
Is it okay to use fabric softener on compression socks?
Never. Fabric softener coats the elastic fibers with a waxy film that reduces their ability to grip and compress. This directly undermines the medical purpose of the garment. Use a mild, dye-free, fragrance-free detergent instead.
How do you get the smell out of compression socks?
Soak them in cool water with a small amount of white vinegar (about a quarter cup per gallon of water) for 15 minutes before washing with mild detergent. Vinegar kills odor-causing bacteria without damaging the elastic. Rinse thoroughly afterward. Do not use bleach — it weakens the fabric.
Should you turn compression socks inside out to wash them?
Yes, if you are machine washing. Sigvaris, Sockwell, and Medi all specify turning garments inside out before washing. This protects the outer fabric from snagging and allows water to reach the skin-contact side where sweat and oils accumulate.
