The brush holder and brush silicone is designed to help keep your juicer clean and running smoothly by making it easy to clean hard-to-reach areas. The brush holder is designed to hold the brush in place while you use it, making it easy to clean the juicer's filter, auger, and other hard-to-reach areas. The brush itself is made of silicone, which is both durable and gentle on the juicer's components. Using the brush holder and brush silicone is incredibly easy. Simply attach the brush to the holder and use it to clean the juicer's various components. The silicone bristles are soft enough to avoid damaging the juicer's delicate parts, but still effective at removing any buildup or residue that may be present.
