I hate cleaning anything. If it builds up, the forced air will push it out like a toilet clog.
I'll rinse the mouthpiece after each use, if there is somewhere convenient to do it. More thorough cleaning only happens if there is sufficient build up of grot to disgust me!
Watch out! You can deform a hard rubber mouthpiece with hot water!!!!!When I get a new mouthpiece I soak it in a jar of Hydrogen Peroxide (3%)
for about 10 minuets then i wash it with Hot soapy water and rinse thoroughly if it has mineral deposits I soak it in vinegar and scrub with a tooth brush. After that I only wash when I notice its gunky or starts to smell.
Although I will rinse it out whenever it is convenient.
As a bonus, it will get greenish with a sulphury stink. Hot water and hard rubber definitely don't get along well.Watch out! You can deform a hard rubber mouthpiece with hot water!!!!!
There is hot and then there is HOT!! You can substitute warm if it makes you feel better. I don't use water hotter than I can stand to put my hands in.As a bonus, it will get greenish with a sulphury stink. Hot water and hard rubber definitely don't get along well.
