Before You Start

Check care labels on each piece of underwear to confirm washing instructions. Separate whites from colors to prevent dye transfer. Use cool or lukewarm water when possible to protect elasticity and fibers. Keep hot water and harsh detergents away from delicate fabrics. Plan to wash underwear separately or with other delicates to minimize friction and pilling. Time estimate: 20–40 minutes for handwash; 30–60 minutes for machine wash, plus drying time.

Step-By-Step: How To Clean Underwear

Sort underwear by fabric type and color. Place items in mesh laundry bag for delicates underwear if using a washer.
Pre-treat stains with a stain remover pen for underwear fabrics by applying a small amount and letting it sit for a few minutes.
Fill sink or basin with cool or lukewarm water and add a small amount of delicate detergent.
Gently agitate by hand for fabrics like lace, cotton blends, or microfiber; avoid twisting or wringing.
Rinse thoroughly in cool water until suds disappear. Squeeze gently to remove excess water, never wring.
If machine washing, place the mesh bag in the washing machine on a delicate cycle with cold water.
For quick refresh, use a portable garment steamer for delicate underwear at a safe distance to remove wrinkles and odors.
Air-dry underwear flat on a clean surface or hang to dry away from direct sunlight to prevent color fading.
After drying, inspect for any remaining lint, stains, or odor and treat again if needed.
Store clean underwear in a breathable drawer or organizer to maintain freshness between use.
Regularly wash the mesh bag and replace any worn-out delicates gear as needed.
For frequent wearers of active fabrics, repeat the gentle routine weekly to maintain elasticity.
