One more question, I have alot of things stuck on my radiator, I know those things are fragile, whats the best way to get all that debre off with out bending all the metal pieces?

Take the compressed air cans to it. dont use a brush, those things are so easy to bend.

compressesd air or a garden hose

I have tried both, but it doesn't take off everything. there are little pieces of debre stuff in the radiator mesh? When I try to brush off it bends the mesh, if I pull out one by one it comes out but just so time consuming?
