In reply to bonebag:
It depends...
If you keep pack your rope up separately from your gear then cross contamination isn't going to be too much of an issue, even if it ended up in the sea or got splashed most people don't wash their ropes more than a couple of times a year unless they look particularly dirty or have grit or sand on them.
If you're going to put the rest of your gear in a bag or cupboard for a month, then a quick wash and dry of your metal gear wouldn't hurt, then lube the pivots on your cams and gates on your krabs. If you're going to be climbing on them several times a week then washing them every time you go out is total overkill, you'll spot if they aren't working smoothly and can clean and lube them before they seize up. Master Cams have a bit of a reputation for seizing when exposed to salty environments, so maybe worth being a bit more regular with cleaning and lubricating those if you have any.
I have heard it mentioned that soft aluminium alloys as used in some cam lobes can be susceptible to developing stress corrosion cracking with prolonged exposure to salt, however that's beyond my technical competence to pass comment on so I'll leave it to others with a better understanding than myself to expand upon if they so choose.
