All our panties can be machine washed in cold water.
If you want them to be longer lasting, follow these steps.
Dab and rub stains with mild diluted detergent
Leave to soak for a few minutes, carefully knead and work into a lather and rinse.
Put into a lingerie bag so the panty doesn't get snagged
Lay your panty on a towel to dry. If you decide to use the dryer, tumble dry with no heat.
