I clean my bong once a week with rubbing alcohol and baking soda, and change the water every day. Honestly after I clean it it’s probably the most immaculate thing I own. As for the glasses, I literally only drink water, coffee, and protein shakes, none of which I use glasses for, but I clean the water bottles after a few refills and my shaker bottle and mugs every time. Now psychoanalyze me.
