RezBlock Concentrate is an all natural resin prevention water treatment that provides the ultimate protection for keeping your bong and water pipes clean.
Just add a few drops to the water in your bong every time you do a water change and you'll save hours of cleaning time.
RezBlock works by creating a slippery coating on the glass that prevents the resin from sticking to it. This means your glassware will look and taste better for longer.
RezBlock Concentrate is especially good for percolator bongs that regularly are very awkward to keep clean but with RezBlock its a doodle.
