I wear a shop apron seems to help.
I use shop towels to wipe it off, wipe and fold till it is done. Also save old shirts and cut them up for rags. I do spray brake cleaner in some areas and wipe it off this seems to work well.
I feel your pain because no matter how careful I am I still get grease on me.
I do wash my tractor few times a year but I think the key is to get the grease off soon as possible so it does not smear and get on everything.
