Stop in for a cup of coffee

What about one of those citrus based de-greasing agents? We got a sample of some Citrusol that would dissolve asphalt yet a bit of it on a rag under the seat of the dirty yard truck freshened it right up.
If I happen to get my drawers or my shirt dirty with grease or grime while working on a car, I keep some Permatex Fast Orange hand cleaner in my laundry room. I rub it into the stains, and wash the next day after it sat on the clothes and soaked in. Works pretty good...
