Sticky Brick Butter is a finish we cooked up in the lab. Food grade and unscented, easy application with the drip tip squeeze bottle, and this will leave your Sticky Brick devices happy and rejuvenated. Simply apply a few drops, using a soft cloth polish with the grain, wait a few minutes, then wipe off any excess. We recommend doing this once a month, but even once every few months will greatly prolong the life of the wood.
