This is a great product that does what it says in half the time it's taken me before. I just poured some into my bong and swirled it around so it coated all the dirty spots. I let it sit for a few minutes and swirled it again...I did this maybe 3 or 4 times. I poured the stuff out into a jar and rinsed the bong with hot water till no more chunks were coming out. Then i poured the roots back in and did the swirl thing a couple more times. After the next rinse, it was about as clean as the day I got it.
