Unlike wood or metal pipes, glass pipes don't really need to be cleaned often because they won't get clogged! But when you have to, just use nail polish remover (smells better than rubbing alcohol), salt and shake! Repeat till clean, then put in hot water to take out smell.
Fill with water to purify the smoke enabling smooth large hits!
