I soap the rods and reels down with a soapy cloth and then gently rinse with fresh water after every use. I used to just rinse with fresh water but a guy that was servicing my reels told me to soap them down. He said teh fresh water doesn't even come close to getting the salt off. I'm careful not to spray with high pressure to keep the water out of the internals.
The VS 250 I am using now is over 3 years old, sent it back once the first year I got it and hasn't been back since. Never cleaned it other than dunking it to get the sand out. The backup 250 I have is still unfished.
The Saltiga I have still is smooth as the first day I fished it. The last fishing trip I had with it was on an island in early November last year. Hung it up and it sat all winter. Fished it the other day and you would never know it.
I take my Stradics apart every week or 2,depending on how wet they got, it's easy enough to do so why not keep them in top working order....I don't want any preventable problems when I get my 50 on...
Steve has all the van stalls also but still rinses them after every trip, better safe than sorry even if its just to get the salt off the line, any reel should be rinsed after saltwater use regardless of price....IMO.........
