How do you wash heated ski socks?

Always remove the batteries first. Most heated socks should be hand-washed in lukewarm water with mild detergent, though some brands allow machine washing on a delicate cycle inside a garment bag. Never use bleach or fabric softener, which can damage the heating elements. Air dry flat—never use a dryer, iron, or direct heat source. Make sure the connector ports are completely dry before reattaching batteries. Check your specific model's care instructions, as procedures vary by brand.
