theres no way to get the smell of bongwater completely out cuz it reeks so incredibly bad... but u can prob scrub it down w/ soap and water and then spray febreeze or something into it... the only problem w/ that is u have to do it everytime and even then the smell wont be completely gone.

as for drinking it... i would never cuz the smell alone grosses me out... but i guess the wine idea might work except that thc is soluble in alcohol so it might not be as stong... but it might not taste as bad.
