That's very easy.
You can remove the glass tube and clean it out with some iso and a tissue.
The innerts can be pushed/pulled from the device and cleaned with iso to as everything is metal. There's just one silicon gasket where a metal filter is pushed in. You pull the filter from the gasket, hold it with a metal pair of tweezers and hold a lighter under it. When it stops burning it's clean. Wait until it's cooled down and reinsert into the silicon gasket. And you're done.
I do this maybe once a month or so... The rest of the time I just poke out the old herb from the chamber, blow into the chamber with my eyes closed (learned that the hard way) and refill. And she's good to go
