This is a video tutorial describing how to clean your skateboard or longboard bearings. The first step is to put your skateboard or longboard into its stand and take off all four of its wheels. Then put your wheels back on the board and then off the board multiple times. This will help clean all of the debris off of the bearings. You should repeat this process at every wheel. Then take all of the bearings off of your skateboard and clean the grime off of them will and old t-shirt and then throw some cleaner into an old water bottle and throw the bearings into the bottle. Close the lid and shake the bottle to get all of the grime off of the bearings. Put your skateboard/longboard back together and you are finished.
