The most effective and cheapest way I have found to clean a bong is to add salt and alcohol and shake until it is clean, usually about 1-2 minutes. Rinse and It is as clean as the day you bought it.
Aye man, I'm all out of high % alcohol so used white spirits + salt, then put it in my dishwasher to get rid of the turpentine.
Do you mean Mineral Spirits. Man, I hope were talking glass. Would not try that with plastic. Vodka will work if you're out of alcohol.
