Cleaning your camera?

[Little John]

I shot an event today called Born Survivor, a tough mudder/guy type obstacle course.


This was my obstacle to shoot






and after 2 waves about 170 in each my camera ane myself were getting a little dirty, I had a cloth to wipe crap away but it was getting pretty dirty so I gave up, wave 3 this was the how things were looking.



and after 7 waves



Never mind the state of me, I was covered top to toe in crap yes the field is normally home to cows so the description could be quite close. so how would you clean yours? I have a tri to shoot in the morning anyone any idea where I could borrow a camera from?
My method probably wasn't the best.



but it is nice and clean again.
