Just a few drops of Rezblock in your piece helps prevent the resin from building up. 

By adding RezBlock to your water, you're actively preventing the resins from sticking to your glass.  Rezblock makes the resin float in the water, allowing you to easily dispose of it down the drain!

RezBlock is completely organic, which means you'll have to change your water out on a regular basis.

With RezBlock and regular water changes, you'll see drastically less buildup in your bong.
