I fill a Bucket with water from the water heater and place my Saltwater reels in it after an Outing... Leave them in there for about an Hour.. the Hot water dissolves any salt that has accumulated from a day's fishing...I'll then run some Cold water into the Bucket to cool the water down. I will then separate Spool from Frame and set them on Old Bath Towels in my Garage, allowing them to air dry over night.
I periodically strip off and Clean the Lines.. with line cleaner.. the Lines will shoot better from the Wash and Cleaning, cause nothing is more annoying then trying to cast salty Flyline...
I will wash down with a old wash Cloth the Rods after each trip, scrubbing every centimeter of rod to get any salt or dirt...
I even soak the flies in hot water to remove salt and stop corrosion (saltwater hooks can corrode if they get nicks in their finish and salt gets in there...)
My Stripping basket gets washed as well, as do my Pliers. the Pliers are then fixed open to dry and a Bit of WD 40 is sprayed into the joint...
about once a Year I use a Line winding tool to remove the Gel Spun backing. It is allowed to completely dry and then is reeled back onto the Spool. Gel spun doesn't rot like Dacron will, but it can get skunky if not taking off periodically and allowed to dry for a number of days...
Seems like a Lot of Work, but Taking Care of my Gear means my Gear will take care of Me when I get into some Big One...
