Monkey Loob's Bearing Cleaning System comes powered by Monkey Loob to give you the best cleaning around. Better yet, you do not need to take off your shields on your bearings, or apply lubricant afterwards because Monkey Loob does all the work for you! Simply soak your bearings, spin them in the cleaner, and wipe off the outer race after taking them out of the liquid. Pop them back in your skateboard, or Roller Skates, and your off! Monkey Loob is a cleaner, lubricant and rust preventative all in one saving you tons of time while giving you the fastest rolling bearing around!
