Keeping your chain clean will help to prolong its life. When dirt and grime get into your chain, it starts to wear out prematurely. With the Muc-Off X3 Chain Cleaning Kit, you're able to easily remove grease, grime and chain oil in seconds. The top of the X3 comes off so your chain can fit nicely into the center, then you put the top back on. You can either spray chain cleaner directly into the device or add it into the top reservoir of the machine, which is then released by a control button. The abrasive cleaning teeth and rotating brush wheels have 120 contact points to cover all the areas of the chain. If you're looking for the deepest clean for your chain then make sure to pick up an X3 Chain Cleaning Kit.
