I'm going to show you two ways to clean your skateboard bearings - a fast, easy way that is OK for your bearings, and a longer, more complicated way that is far better for your bearings, but takes a lot longer. You should clean your skateboard bearings if your bearings have slowed down, seem kinda mucky, or if they make a gravely, junky sound when you spin your wheels. To avoid getting to that point, you should really clean your bearings fairly often, even when they are only a little dirty, or just haven't been cleaned in a long time. Cleaning your "roller skate bearings" like this from time to time will increase your bearing's lifespan, and improve your skateboarding experience 

First, you'll want to remove your skateboard bearings. You can clean your bearings without removing them, as I'll show you later, but you won't get them very clean that way. To clean your roller skate bearings well they need to have been removed from your skateboard wheels. Not sure how to do that? Pause for a second and read How To Remove Your Skateboard Bearings. It's quick and easy.

The 2 Different Covers on Bearings have quite an impact on the care and Maintenance as well as the longevity of the Bearing. If you have a Sealed Bearing that would mean the Bearing Cover is Rubber or Neoprene and will keep the Elements out of your Bearings, which can make your bearings last longer, however this will create Drag on the inner raceway if there is any Contact with the Raceways.

A Shielded fag Bearing has a metal cover on the Outside of the Bearing and is Attached to the bearing either by a Clip (Serviceable) or is Pressed into the Bearing called a Stake Shield (once removed it cannot be re-installed) and is most Common.  Shields do not keep the elements out as well as a Seal but there is no drag on the Bearing whatsoever making it a Faster Bearing as there is no Contact with the Shield. It is also easier to maintain a Shielded Bearing as you can lubricate the Bearings without having to remove them.

You should clean your skateboard bearings if your bearings have slowed down, seem kinda mucky, or if they make a gravely, junky sound when you spin your wheels. To avoid getting to that point, you should really clean your timken bearings fairly often, even when they are only a little dirty, or just haven't been cleaned in a long time.
