excersizing thru hull valves

I wonder if any listees have a better method of keeping thru hull valves
working smoothly, especially the forespar marelon models.

Just before relaunching each year we go around to each valve on the outside
of the hull. We place a glob of silicone grease on the end of a wooden
dowel and use that to transfer the grease to the inside of a closed valve.
Then from inside the boat we work the handle back and forth. Our marelon
valves are now ten years old and get stiffer each year. Maye the plastic
swells up.

Any suggestions.

Richard, we, too, have Marelon seacocks, two of them. We also grease the
outside of the ball during our annual haul-out, but we use Super-Lube, a
synthetic, non-silicone grease. I don't know if that makes a difference or
not. We also try to get some grease on the inside of the ball by using a
coat hanger with a very short bend on the end. Putting a glob of grease on
this bent end, inserting it through the open seacock, then closing the
ball, but retaining enough room to move the wire around, we think that we
are able to get at least some grease on the inside of the ball. Don't know
if that makes a difference either.
Our seacocks have been in continuous use since 2007, though they are stiff,
they are always easy to move once the initial reluctance is overcome. They
don't seem to be any worse now then when new.
An interesting question for Forespar?

I have metal ball valves but you may want to pour in a warm mixture of a
barnacle buster type cleaner (I use citric acid) and water on the ship
side, then  opening then valves just a twit bit and then wait for the
liquid to seep into the valve and do its magic.

I would doubt that any certification society would allow sea water
isolation valves to swell over time.
