Same as how i clean exactly. 2 foot glass bong with a slide the main piece at homeMy bong I clean weekly in the sink with HOT water running through it then fill with ISO part way shimey shake dump out and rinse the crap out of it with HOT water again finish rinse with cold water so I don't hit a hot pipe that is the only time my bong gets cold..... I've have many bongs with ice catcher but rarely used them cause after the ice melts the bong is too full
My latest bong is a recycler I am very happy with that
