The ECM brand grinder cleaner removes coffee oils, odors, and flavor residues from the grinding disc and extends the lifespan of your coffee grinder with regular use. The application of this product is completely safe due to the use of food-grade natural substances. Remove the beans from the bean container of your grinder and let the grinder "run empty." Then, add a packet of the special cleaner to the bean container and perform several grinding cycles. After that, refill the bean container with beans and carry out 2-3 grinding cycles to remove any remaining traces of the cleaner. Your grinder will then be ready for use again.
