I'm trying to clean the grease off the range hood. Even using a "pro

Is there an even heavier duty grease cleaner?

Ammonia water, detergent, and alcohol work pretty well, at least when I mix
them up myself. You could always try simple green, which works pretty well
also.

Beyond that, lye or mineral spirits.
