This is a trick question... isn't it?
Mechanics use MEK: Methyl ethyl ketone (butanone), a solvent.
Not safe for use or storage at home.
Oderless Mineral Spirits
aren't safe either(<see the pdf safety sheet) although slightly better than MEK. No solvent is safe for use outside of the shop. Or... safe to be stored anywhere around a home.
I have used a little choke cleaner (from a spray can) to clean parts. The choke cleaner just melts the dry grease off. It must be used outside... ONLY.
Other than that... simple green in a spray bottle, rubber (dish washing gloves) and a stiff brush works great.
