Do you ever need to clean your bearings on your skateboard? If you do, then do you need to put oil on it?

Will the bearings rust if you wipe them with a paper towel?

i've had the same bearings for about 5 years and the only reason why is because of my bearing protectors. i have never cleaned them but i need new ones now. i dont think you should clean them. you should probably buy bearing protectors and you'll be fine. my board has been waterlogged about 3 times and my bearings still survived because of the protectors. well gl skating
