When washing bearings, lightly rinse them down. DO NOT use a high pressure hose directly onto the bearing, as the force of a high pressure hose can penetrate water into the bearing and damage its integrity.
The state of your bearings should be checked periodically. If you can feel a rolling resistance or hear a grinding noise when the wheel is turned, you should consider bearing replacement.
