Out of all the great mysteries of the universe we might never understand — how the Great Pyramids of Egypt were built, why people disappear in the Bermuda Triangle and whether or not aliens exist — there is one mystery that we’re absolutely qualified to clear up: how to wash Knix period underwear. (If you’re in a rush, scroll down for our TL;DR tips)
Though everyone wears their period underwear differently, it all ends up in the same place at the end of the day — inside the laundry basket, holding onto period blood for dear life (that’s what it’s designed to do!). But if the thought of allowing up to 8 tampons worth of blood to mingle with your teen's beloved clothes makes you nervous, we’re here to reassure you, there’s no need to worry!
Further reading: What is moisture wicking underwear?
When you wash period underwear in the washing machine, laundry detergent (we suggest a mild detergent) helps to separate the blood absorbed in the period underwear from the fabric. After the initial wash, the dirty water drains out of the machine and refills with clean water for a rinse cycle. It’s the same science that makes sure all your dirty clothing comes out clean after a wash – a little period blood or sweat isn’t going to make a difference. (Kt by Knix undies are quite moisture wicking, which is great if you need a pair of "sweating underwear" aka underwear to absorb your sweat.)
Washing period underwear is quite simple—it's just like washing any regular underwear! But if you’re still concerned about period blood stain getting on your teen's other clothes, you or your child can always do this: rinse period underwear in the sink and gently rub the gusset before popping it in the laundry machine. Keep in mind this step is not necessary.
We have a few tips when it comes to washing which will help preserve your Kt by Knix period panties for as long as possible.
1. Wash period underwear in cold water.
Heat can damage the elasticity of the fabric so if you want to maintain the perfect fit of their Kt period underwear, be sure to select the cold wash cycle on the machine. No need to hand wash period underwear or set the machine on a delicate cycle; these period undies can withstand up to 50 washes. Be sure to use a mild detergent, and do not add fabric softener.
2. Put your underwear in a mesh laundry bag.
The mesh bag helps protect delicate items from getting damaged in the wash, and also makes it much easier to find your underwear when transferring the rest of your laundry to the dryer.
3. Do not put period underwear in the dryer.
Unless it's our Super Leakproof or Cotton Modal Super Leakproof underwear, which are safe to tumble-dry on low. Otherwise, the heat and agitation of a typical dryer will break down the precious absorbent fibers in the fabric that make the underwear so great. Plus, the dryer heat might also alter the fit of the underwear. Instead, allow them to air-dry naturally on a clothing rack (or hook, or back of a chair). When you let period underwear air dry, it will preserve the undies for much, much longer.
And that’s all you need to know about how to wash your teen's Kt period underwear! Sit back, relax, and go on with the rest of your day.
