The Resin Preventer

There’s something about a water pipe coated with resin that just makes us feel dirty. That’s why we change our water every day. But that’s not all. Not by a long shot. We also use RezBlock. Just a few drops help prevent the resin from building up. It keeps our pieces clean, and our hits fresh and delicious.

When you add RezBlock to your water, it prevents the resins from sticking to the glass and instead they float in the water allowing you to pour out that gunk along with the ash and other particulates you don't want. RezBlock is completely organic, which means you'll need to change your water out regularly. With RezBlock and regular water changes, you'll see drastically less buildup in your bong.

good stuff

I am buying my second bottle today. I have gone from having the dirtiest bong in town to the cleanest.

Rez Block is worth it

I have a mini-rig which is incredibly difficult to clean. Rez Block completely stops resin from sticking to my glass. It’s worth it.

Love, love the Rez block

It has made cleanup a snap. Most of the time I don’t even have to use a cleaning tool. I just run hot water through it and it just comes right off the sides of a bong.
