It’s not really a question of fast or slow…it’s just that my mind is best stimulated by absurdity…keeps me awake. Kind of an ADD type thing.
Here is the ultimate and safe way to clean.
Put a couple of inches hot water in sink. Mix in some Cascade Complete (dishwasing machine stuff). Use only that brand, it has enzymes that eat the crud out. A minute of agitation is all you’ll need.
Let dry.
Put a little soapy water into the mouthpiece to prevent condensation.
Good for a month at least.
