Have all you nice people talking about using a hoover, every actually taken the bumper off and separated the rads? I just did mine at the weekend.... there is little to no chance you could possibly hoover them clean. I've now done two different cars over the years and both times have found full leaves etc etc in-between them. Also the corners silt up, and it's that that causes the corrosion. But in saying all that a good hoovering cannot do any harm, but you'll still need to take the plunge....
