Cleaning Hydroponique couldn't be easier. Take out the glass bowl, glass stem, and silicone ice catcher, then put all four components (including your water pipe) in the dishwasher.
Alternatively, you can clean all these components by hand with a gentle soap and a toothbrush.
Avoid exposing the silicone components to a direct flame. Though silicone can withstand higher temperatures than plastic, it can blacken and burn.
DISCLAIMER: Though Hydroponique's silicone components are shatter-proof, the glass components are not. Handle these with care.
