There is... The Chemistry offered by
"Purple Power". An example of of its Dirt, Grease and Carbon Busting Power is the use of it inside of a thoroughly coated, nasty Electric Oven and Stove Top Burners where simply spraying this Non-Toxic "Purple Jesus" on everything therein ....and walk away for an hour or so. When you come back... You can clean what is left by simply wiping the "Black Mung" off with a Sponge and Deep Bucket of Warm Water.
The only Cautionary Aspect is NOT leaving it in direct contact with Aluminum for TOO long...or it will leech out Aluminum Oxides on fully submerged Aluminum Parts. If you spray the stuff on your interior wheels... check the condition of the metal surfaces within the first 30 Minutes and you should be Okay. The stuff has No Noxious Smells and you can use your Bare Hands in contact with the materials. It washes off in the Sink for small parts and pieces...or a Garden Hose for your Wheels. Using a Scotch pad in concert with this material will allow you to get MOST of the Gummy Gunk removed.

Another assist in Cleaning Up the Bolt Up Flange Face is to take a few Box Cutter Razor Blades and use some Duct Tape to provide an EZ Grip along the narrow-Non-Sharp Edge...and Drag the Blade along the Flange Face... BACKWARDS. If you are careful... you can also radius the Lug Nut Holes to remove any Crud in there and the Metal casting Surface will NOT Be Damaged.
