Bought a nice small glass bong while on spring break during my college days but in the making of many memories, it got so choked up with black gunk that I couldn't get a hit at all and if I could was not enjoyable. I couldn't bring myself to throw it away so it went into a box with all the other things I can't throw away and there it had sat ever since.  I got ROOTS Eco Tonic as a gift and tried it out.  Not ashamed to say, I had tears in my eyes when I saw how well it worked!  It couldn't get all the tar off the bottom so I threw in some salt with the solution and tried again - not even 5 minutes later it was as clean as the day I bought it.  Call me sentimental but it was like reuniting with an old friend I hadn't seen since college.  This is great stuff....will definitely use it again!
