Finally, a bearing cleaning unit brought to you by the bearing company by which all quality standards are measured. This unit is made of flourinated high density polyethylene and is designed to clean up to 8 bearings at a time. They are separated on a pin by 7 spacers to insure good flow of the cleaning agent throughout all the bearings and allowing more room for the debris to work it's way out. Unfortunately, due to extremely stringent shipping regulations, we cannot supply a cleaning agent. We recommend high purity alcohol or acetone, which can be found at your local hardware store. Some of your local skate shops may carry citrus cleaners or some other solutions which do work but are oil based and will leave a film on the internal workings of the bearings. When using the bearing cleaning unit and ANY solvents, please make sure to work in a well ventilated area that is not near an open flame. A detailed instruction sheet will also be included with the unit to insure easy and proper use.Bearings and Solvent are not included.
