A cleaning material for use in a device comprising a grinder comprises at least one organic material processed to retain hygroscopic properties while having reduced components leading to gelling or thickening of the at least one organic material, as well as a binder and a humectant. In an embodiment, the cleaning material comprises about 80-89 wt % of the at least one organic material, about 10-15 wt % of the binder and about 1-5 wt % of the humectant. In another embodiment, the at least one organic material may comprise malted wheat grain that is heated for 30-40 minutes at approximately 150° F., followed by further heating in successive 30 minute intervals in which temperature is increased in each interval by 50° F. until 400° F. is reached, followed by further heating for approximately 2.5 hours at 400° F., followed by introduction of water into the rotating drum and forced air cooling.
