And on the Glavan Reel website about maintenance of the Rush:

Maintenance and Cleaning

We recommend that you that youclean your reel every time after exposure to salt or alkali enviroments. To clean your reel, first loosen the drag all the way counterclockwise to the lowest setting and remove spool from frame. Soak both in fresh warm water. After saoking rinse both spool & frame thoroughly making sure the drag area gets a little extra attention. Inspect the pawl area on the frame and the gear area on the spool for dirt, grit, or build up. If found rinse a little more aggressively. Let the spool and frame air dry before replacing the spool back onto the frame and storing.

But I could be wrong.
