The mask itself can be cleaned as follows (instructions are usually printed on the packaging):

wash with warm water and soap. Flush with clean water. Then dunk it into a solution of 1 part bleach to 64 parts of water for 10 minutes. Flush again with clean water and let it air-dry.

The one-way valve can be used repeatedly on training with a manikin, but it needs to be replaced after use on a real person.


Perhaps it's better to order a mask specifically for training purposes and one for 'real' use? Their not THAT expensive..
