when PlastiDipping my bumper, there was spray through that coated the fins of my Air Conditioner Condenser. I can't figure out how to recover from this one.

I can't power wash it, it will bend the fins.

The fins are small, fragile and narrow, so I can't use a fun tool because they have gaps between the fins.

I have tried WD40, PB Blaster, GooGone, Kerosene, paint remover, and half a dozen other remedies, but nothing I have found disolves this stuff to where it drips out of the fins by itself.

Anyone got a solution here? Is dip disolves the only thing that will work to where I can just use a garden hose to gently rinse it down without destroying the condenser?
