Default Radiator cleaning - exterior

I can see some junk on the exterior surface/fins of the radiator in my 95 LT1. Is there any easy way to get a hose behind the radiator and blast that stuff out of there? What should be removed?

Thanks, John

There is a paper in the tech papers section of the forum on how to do this. It is not too hard to do just take your time. The fins are so soft that they will bend if you blast them with water or air. It is a mostly 'by hand' job that takes time. It will make a difference in the operating temp of the car and is very worth the effort.

Remove the radiator shroud, and pull the stuff out. Be careful when you spray it NOT to get the Opti wet.
