How To Actually Wash Period Underwear

As Period Panty Reviews reminds us, the first thing to remember is not to panic if your pair seems thoroughly soiled after use, as the designers made them to absorb menstrual blood. In fact, many brands are not only made with stain-resistant fabric, but also feature a black absorbent liner layer, regardless of the color of the panties, to help prevent leaks and stains. So when it comes time to wash them, fear not: they can probably handle both their job and the cleaning process like champs. So how do you clean them?

First, it's a good idea to hand-rinse your period panties in cold water to remove as much of the fluid as possible. This will help prevent staining and also ensure that the panties get thoroughly cleaned in the washing machine (via The Period). Next, you can put them in your washing machine on a gentle cycle with your usual detergent in cool or cold water. You shouldn't any additional stain remover spray or treatment, as the fabric is generally made to withstand blood. When finished, it's a good idea to hang them to dry rather than tossing them in the dryer to preserve the shape and protect the absorbent layers of fabric. That's it!
