Winter Maintenance for Ballast Tank and Water Valve/Seal hardware

I am a new 26S owner based in NL. I have pulled my 26S and am storing on the trailer for winter. The ballast tank was filled with salt water all summer and moored along a wharf. I am wondering if the ballast tank and water seal valve requires any seasonal maintenance? Had no issues this year and if some maintenance is a good idea I would like to keep the tank and valve working optimally for next year.
Thanks for any replies.

I used to keep pool chlorine in my tank while it was slipped. Never worried about the valve seal.
I did keep a spare siphon hole plug on board. Make sure there's a cotter ring on the valve handle so you don't accidentally unscrew it from the threaded rod and lose it.

I know that vegetable oil is recommended to keep o-rings and seals playable on marine heads.... I guess it would not hurt to rub a rag dampened with vegetable oil over the seal. Might not help either.... just saying

We've pulled ours apart occasionastateo lube it with petroleum jelly. If the boat is stored in salt water keep an eye out for porosity corrosion. Especially at the seam around the bottom plate.
Ours had been seasonally stored at a dock in the Fl keys. The first time I tried to test the ballast tank on the trailer the bottom plate snapped off.
Happily it was on the trailer and a new assembly was available from Blue Water Yachts.

Oh and what is this winter thing everyone keeps talking about?

Just completed winterization here today - added air to the cold fenders. Took less time than changing the clocks to standard time.
