This bong is simply incredible, easily my new favorite by a lot.
That being said there is one thing that I was worried about when purchasing this... cleaning
I am so happy to say it's simply not a problem. There is a YouTube video on this page that shows you a way to clean this but I'm sorry to say nobody has time to follow the directions as shown.
Please do yourself a favor and when you're draining the inside of the orb do not stand there and wait for minutes holding it upside down. Just blow through the mouth hole. It may get a bit messy, and you may get a taste of your preferred cleaner but it's gonna be so much quicker for the bulk of the draining. Use that saved time to rinse out a few more times just to be sure all that cleaner is gone.
Speaking of cleaner, with the recommended amount of isopropyl used in the video, you should instead buy a dedicated glass cleaner. You can use much less volume and probably save yourself some money. A lot of the glass cleaner formulas on the market today also come with a water-soluble grit component like salt and require no time to soak another time saver.
