Just replacing a condenser on one of the cars, noticed obviously the old rad is pretty dirty (no bent fins though) compared to the fresh new part.

Anyone got any tips for cleaning the fins and getting a bit of the original colour back?

I've seen people recommend silly things like pressure washers etc, that is out, the rad is on the car and I was wondering if there was some sort of wonder chemical that I could lightly spray on and have it take the filth away.

Only thing I can think of right now is spraying some panel wipe into the fins, and using a super soft make up brush.

Wishful thinking really but I wondered if there was some mildly acidic solution out there which might just lift some of the dirt off without causing more harm than good.

Danke.
