As stated earlier, I have a Hotbox. Mine's red. The tube gets gross and brown dirty. I haven't found a good way of cleaning that, so I replace them. The good news is you can buy it at your local hardware store for like 69 cents. I boil the glass parts to clean them. Finally, I just wipe the box itself with a wet wash cloth. Everything is shiny & new!

The most amazing thing I have noticed with my Hotbox is I can seriously leave it on for like 8 hrs with no problems. On the weekends, I'll turn that baby on when I wake up, and vape all fucking day. Its really wonderful, man. Being full body stoned all day makes for one awesome day if you ask me!

Happy Vapping!!
