NEVER ever use any petroleum product on the aluminum clutch face's.........why, they are cast and porus, yeah I know they don't look porus, but to prove it to yourself take an old clutch and heat it and weld on the clutch face, you will have black goo coming out of the aluminum and really contiaminate your weld. If you use brake cleaner, carb cleaner, acetone etc etc, when it hits that surface some of it soaks in and takes some of the oil and grease on your clutch surface with it. When you get your clutch real hot, just when you don't need it happening, the soaked in grease will come back to the surface. slippery slimey slew
Now............if you run a billet cnc machined aluminum clutch......READ NOTHING THE FACTORIES SELL, then the stuff won't soak into the more dense forged aluminum that most guys would be machining clutches out of.
And if none of that makes sense, save your self a lot of thinking and sled maintanence grief and............just stick to good dish detergent and scalding hot water, clutch faces and belts.
