BB maintenance

HI guys,

I'm on the hunt for a 'squeak'. Think it might be coming from the BB so having now armed myself with a crank puller and BB removal tool, I took the BB out last night. Its a sealed cartridge BB. I've searched YouTube/Sheldon Brown/Park Tools for information on servicing/lubricating these and can't find anything so I'm wondering...are sealed cartridge BBs not serviceable? If not, should I be lubricating them anywhere and if so where?

The outside casing of the BB had some dirt and slight corrosion on it, so I'm going to clean that up and the retaining cups on either side were also fairly dirty so will clean them too, but is there anything I should be doing with the BB?

Cheers

    Thanks - just didn't want go looking for a new one cos mine had had it and someone turn around and say it'd would have lasted longer if you'd greased it every now and then...

    It sounds and feels ok out of the bike, so I'll clean it up externally and try it again, see if that stops the squeak!!
