Wash your ooia once before the first use.
After wearing your ooia, it is best to wash it by hand in cold water.
Then you can put it into a laundry net and into the washing machine and wash it at 40 degrees ideally in the easy-care wash cycle - you can also do this along with other dark laundry. Remove the gel pad before washing your ooia.
Please do not wash your ooia with heavy duty detergent, as it is too aggressive for the wool. Instead, ideally use wool detergent.
Please do not use bleach or fabric softener, as this will limit the effectiveness of ooia.
Please also do not dry clean - but who takes their underpants to the dry cleaners?
Ironing is also a no-go, just hang ooia on the clothesline and it will soon be ready to wear again.
If you treat ooia 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.

Because your health is our top priority, we've sought the opinion of gynecologists on the requirements for bacterial growth inhibition.
These gynecologists confirm that it is fundamentally important that period underwear inhibits bacteria growth - and that high-quality, tested fabrics are used for this purpose.
Our membrane system has bacteria-inhibiting properties at the crucial points -so that neither bacteria can 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 § 28 paragraph 8 of the Chemicals Act. Of course, we do not use any nanoparticles that are controversial in terms of health.
The bacteria-inhibiting effect of the silver chloride takes place directly in the fiber.
The Hohenstein Institute carried out elaborate testing on our ooias to ensure its antibacterial activity.
The Hohenstein Institute is a very renowned German textile testing and research institute, which awards various certificates.
ooia is the world's only period underwear whose function is certified - we are proud!
