Press the mouth cap with nose clamp around your nose well.
6. Wash the mouth mask in a pan with water
You can place the mask in a pan with hot water and boil it, which saves a lot of water and energy compared to washing in the washing machine. Boil the mouth mask for at least 15 minutes to kill all bacteria. Drain the water and take the mask out of the pan with clean, washed hands or with latex gloves on. Dry the mask on the clothesline. Are the masks dry? Then remove them from the clothesline with clean hands or latex gloves and put them in a sealable plastic bag, such as a ziplock bag.Be careful when you remove the mouth cap from the pan. The mask will be very hot.
6.1 Washing in the washing machine
Put the mask in a washing bag and wash with a short washing program at 60 degrees or the other indicated temperature in the mask. Spin on low speed. Remove the mask from the washing machine with washed hands and hang it on a clothesline to dry.
