How to clean cooling fins?

What is the proper way to clean these "cooling fins" on the oil cooler for this Vanguard EFI 28 HP engine?

I took it off the engine and used a brush and shop vac to get most of the debris out, but there is still some in there.

Could I let it soak in dawn dish soap and warm water and hit it with a brush again? Or blast it with a pressure washer?

Air compressor is what I use, I try to stay away from water if at all possible. Sometimes squirt on some brake or carb cleaner and blow it off with an air nozzle if it's oily.
