How to care for your sleeping underwear

With all your newfound rest, you may be ready to tackle more throughout your day. But, thankfully, cleaning your sleeping underwear is not one of those things on your to-do list.

Be kind to your sleeping underwear by using the delicate cycle with cold water and a gentle soap. If you want to add a little razzle dazzle to make them extra clean and smell fresh, toss in a little vinegar or tea tree oil during the rinse cycle. Hang tight as they hang dry - depending on your underwear’s absorbency level, they might take up to 24 hours to dry fully.

Extra tips:

  • Give your underwear a rinse in cold water before washing.
  • A mesh bag will keep your underwear in great shape for longer.
  • Instead of wringing them out, blot out excess moisture before hanging to dry.
