In this tutorial, we learn how to clean skateboard bearings. You will need: a socket wrench, a dirty skateboard with dirty bearings, super glue, rubbing alcohol, and an empty glass jar. First, use the wrench to remove the bearings from the skateboard. After this, pour the alcohol into the jar, then drop the bearings inside. You can also drop in other parts that need cleaning if they fit inside the jar. Now, place the lid of the jar on and shake it for about a minute. When finished, let the solution sit for around 5 minutes. After this, drain the alcohol out and place the bearings onto a towel on a flat surface. To finish, place the bearings back onto the skateboard and wheels, and you are finished!
