Every morning when you take your mask off, you spray it on and walk away. It disinfects, then turns to water and dries completely by evening, and smells like nothing.

I like it because it makes everything very easy, and it works: when I have a cold that won't go away, I spray the CPAP mask with it each morning and the cold goes away in a day or two.
