RezBlock is an all-natural solution that you add to the water in your clean water pipe. RezBlock will prevent resin from sticking in all areas that the mixture is touching.
RezBlock is made from organic ingredients - all of which you can buy in a health food store (like Trader Joe's). The full ingredient list is not disclosed because it's a proprietary blend. They use fruit and vegetable extracts to make RezBlock and add salt which acts as a preservative and food coloring to make it look pretty. There are no chemicals or any other ingredients that would be unsafe for human consumption.
