On a pinch you can use regular white rice to clean your grinder, however, this stuff really does a great job and it is worth the price.
One jar contains 15.2 oz (430 grams). We recommend using 35-40 grams (1 cap full) for espresso grinders and 70-80 grams (2 caps full) for shop grinders. Thus a jar will do about 12 espresso grinder cleanings and about 6 shop grinder cleanings. It is recommended to use Grindz™ for espresso grinders once a week and for shop grinders once a month.
The world's first and only product for cleaning coffee grinders, Grindz™ Grinder Cleaner is a patent-pending innovation launched in June of 2005. The product is an all-natural, food-safe, and flavor neutral combination presented in coffee bean shaped tablets. Grindz™ quickly and effectively removes stale coffee residue and flavored coffee odors from the internal burrs and casings of coffee grinders. Requiring no grinder disassembly, Grindz™ users simply run the product through the machine just like coffee.
Grindz™ is very effective at eliminating the scent of flavored coffee from a grincer. It is particularly effective in removing the odor of flavored coffee when it has accidentally been passed through the dedicated "non-flavored" grinder.
Can I use Grindz™ on a fully automatic espresso machine? While Grindz™ will effectively clean the burrs on most any coffee grinder, we do not recommend use of the product on fully automatic espresso machines without specific instructions from your machine's manufacturer. The reason we urge caution is that the brew chamber of each fully automatic espresso machine is different. Although Grindz™ is fully edible and food safe, the composition of the product gives it a tendency to expand when put in contact with large volumes of water. Therefore, when using Grindz™ on fully automatic machines, it is important to not accidentally "brew" a shot of Grindz™, as this could clog your machine. In order to avoid this, ask your manufacturer how to set your machine for grinder cleaning. If you have already tried and succeeded using Grindz™ on your machine, then you've figured it out!
