I'm looking for recommendations on engine cleaners, not brighteners like S100 but a chemical that will actually get the **** off my cases (see below). I'm looking at Gunk Foamy since it calls out dirt and road grime instead of grease, which is not an issue on my bike. Any personal experience or recommendations?

 

Simple Green and a brush. Then hose it all off under pressure.

 

Undiluted? Hosing is going to be a problem in the shop, in the winter, in Minnesota.

 

Spray bottle as it comes. Can't help that you don't have water and a heated shop available.

 

Shout laundry spray

 

Shop is heated and cooled and humidity controlled, just not shooting water everywhere.

 

Really? That works? No grease, just road grime.

 

Another vote for Simple Green. Wait for a day when it’s 35-40 degrees so you can rinse it outside.

 

Dilute the Simple Green 50% with water.. It will still clean very well and be easier on the bare aluminum parts and pieces.

 

And another method is steam. Good for other stuff also.
