Gunk engine degreaser.


You can by whatever brand engine degreaser at any auto parts store.


That's what it's made for. To clean dirty, oily, greasy, grimy engines.


Spray it on, let it sit for 10 min, then hose it off.


It works great and does what it's supposed to.What is the best way to clean oil stains in between the fins of a motorcycle engine?
If you really want to get excellent results without busting your marbles, try to get some Methyl Ethyl Ketone (MEK), it works like a dream, just make sure you do not get any plastics in contact with it.
A motorcycle is not pots or pans. Do not use household cleaners on it! Use products designed for your motorcycle go to a local dealer and check out the products they carry. To get between the fins use a spoked wheel brush.
DO NOT USE EASY-OFF!!!!!!!!!!!!!!!


Caustic cleaners will eat your aluminum.


It works great on iron blocks, though





Gunk degreaser is made for it.


The thinner will do it too, but you may not want that on the clearcoat on the cases.


Spray can citrus-based degreasers work ok.


I've got a few small stiff bristle nylon bottle brushes I'm gonna try out.

Another trick to add to the pile of good advice here: Lacquer Thinner.





Not regular ';paint thinner'; or ';mineral spirits'; -- they won't work.





Lacquer thinner will do the job. Apply with a brush you won't use again, and don't get any on the paint or plastic. Don't splatter any on your car, either!
Try WD-40 and wash it off with soap %26amp; water....





Also, if you are really serious on getting the oil stains


off the fins.


Get some long extended q-tips and remove the oil stains


by hand.





Also, check you local auto parts store like


Pep Boys or Auto Zone....They probably have


a product that you can use.
use degreaser and cotton buds need lot of time then powerwash off
w-d40 then wash with soap and water
use the diesel or thiner and wiper with a clean paper tower until it dry before you start the engine
the easiest......easy-off oven cleaner


and rinse w water......do your whole motor if you want.....
