Washing and disinfection
The masks are washable at 60° C and should be washed at this temperature.
This temperature has already a disinfection effect.
In addition, they can be ironed on level 2 (150 °).
If the mask has lost the crease after washing, grasp it on both sides and tighten it, which will make the wrinkles reappear and then iron the mask at level 2 (150°).
Do not iron the rubber band!
