Now don't get ahead of me here. I know how to clean my bongs, I own a fair amount of them. I am posting in this section because I didn't see any sections for units themselves. I have this nice glass bong I have been using for company and smoke get togethers. Normally growers and what not come over and chill time to time. Issue with this unit itself is that who ever owned it before obviously didn't take good care of it because it has a nice film of ash/resin caked inside of it as if it was a small pool of water for ash and the fucker just let it for a month to dry. As you can see in the pics it the ash catch needs to be cleared out. Now don't get me wrong I have tried lots of ways to get at it but it is proving difficult. I have managed to scrape away a good amount of it myself so far, the first chamber down the ash catch from the bowl itself used to be the same as the part I cannot get at, when scraping it all out it came off in flakes like fucking fish food. I use 99.9 and salt normally to clean my glass, I have tried rock, sea, and table salt for it so far and no luck cleaning it out without actual physical scrubbing and scraping like the first chamber. My question is, how do I clean out the parts I cannot get at? Sorry if I posted in the wrong section.
