Gunk works great.
You also have a tank load of cleaning solution in your fuel tank.
Diesel works good for cleaning grease and crud, but you'll miss the
buzzzzzz, from the either, and you won't get blown to the moon either,
if you decide to have a smoke while cleaning whatever.

Cleanng stuff with ether is nuts.
Very Dangerous, and hard on your health.
