Shimano Bottom Bracket

Dear internet,
I have a 2009 Spesh Stumpjumper Elite FSR and have enjoyed a full year of carefree riding. However, I took part in the Chain Reaction Cycle's Marathon two weeks ago in a mud bath. I went through my usual cleaning routine afterwards but when I went to take my bike out this weekend the bottom bracket had seized. I rode it round the block a few times but this hasn't free'd it up.
The bottom bracket is a Shimano FC-M542. Can these be stripped down and cleaned or will I have to buy a new one? Any help or advice would be appreicated.
Cheers

I strip down my FSA external BB to clean & de-grease, take your time - you don't want to damage the seals, I used wooden tooth pick the fist time but now I know how it comes apart I use a very small srewdriver and my finger nails.0

Or warm up the grease insert in a syringe and inject it in leaving the seals in place..
but since its likely to have gone rusty I would replace it.0 -
mm grease that get thin when warm..
no thanks a constant viscosity is best as it will not thicken when cold."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

"no thanks a constant viscosity is best as it will not thicken when cold"
all greases thicken / thin depending upon temperature; the oil within the grease changes viscocity as it is cooled or warmed.
HOWEVER, warming a grease to inject it as mentioned above is unlikely to be effective as it won't thin that much.
pop the seals, scrub with some solvent / brake cleaner and regrease...if this doesnt work, CRC !0
