Before doing anything let it dry out the you can normally dust it off .
uncle do i need to disassemble the motor to dust it off.?
EDIT:
Some of them recommend (and some even insist on) periodic lubing of the bearings.
My personal experience with a brand called Scorpion. They pretty much insist that the bearings be periodically lubed.
anwar uncle what kind of lube do people use for brushless motors.?
