I always soak mine in vinegar overnight and it loosens everything up. Then I wipe it with a pipe cleaner. You can put it in boiling water too, that is a quick easy way.
rnf232s Reviewed by rnf232s on . How would I go about cleaning a pipe? I used QTips to clean the mouthpiece area of my 5 inch pipe (it has a mushroom shaped thing at the front, not a typical spoon glass pipe). I cannot clean the bowl however. The alcohol bag method does not really work either. Any suggestions? Rating: 5
