After wearing ooia, it's best to wash it out by hand with cold water
Then it goes in the laundry net off in the machine at 40 degrees easy-care wash cycle - gladly also together with other dark laundry - it will carry no damage from it, really!
Please don't wash your ooia with full strength detergent, as this is too aggressive for the wool. Instead, ideally use wool detergent.
Please do not use bleach or fabric softener, as this will reduce the effectiveness of ooia.
Please also do not dry clean - but who takes their underpants to the dry cleaners?
Ironing is also taboo, just hang ooia on the clothesline normally and it will soon be ready for use again.
If you treat ooia this well, it will retain its full bacteria-inhibiting effectiveness for about 2 years. After that, of course, you can still continue to use them as "normal" underpants.

We sought the opinion of gynecologists on the requirements for inhibiting bacterial growth because your health is our top priority.
These gynecologists confirm to us that it is fundamentally important that period underwear prevents bacteria from growing - and that high-quality, tested fabrics are used for this purpose.
Our membrane system has bacteria-inhibiting properties at key points -so that bacteria can neither multiply nor develop unpleasant odors. Our active ingredient silver chloride is tested under the strictest conditions and may be used in Germany in accordance with Article 89 of the Biocide Ordinance in conjunction with Section 28 (8) of the Chemicals Act. It goes without saying that we do not use any nano-active ingredients that are controversial from a health point of view.
The bacteria-inhibiting effect of the silver chloride takes place directly in the fiber.
We had the Hohenstein Institute perform an elaborate testing procedure on ooia to ensure its antibacterial activity.
The Hohenstein Institute is a very renowned German textile testing and research institute that awards various seals.
Incredible, but ooia is the only period underwear in the world whose function is certified - we are proud of that!
