The Bones Bearing Cleaner Bottle is designed to clean up to 8 bearings at a time.
Bearings are separated on a pin by 7 spacers. This is to ensure adequate flow of cleaning agent through the bearings and allows for debris to work its way out.
Bones recommends high purity alcohol or acetone, which can be found at your local hardware store.
A detailed instruction sheet is included with the unit to ensure easy and proper use.
