I noticed that the first radiator (AC?) has collected some bugs and I imagine the radiators behind it also have a few bugs. What is the most effective way to clean them? I have a pressure washer.

That's the intercooler.

The bugs will deteriorate over time, I wouldn't risk bending any fins with a pressure washer, although light pressure should be fine.

I just use a regular hose and spray it down.

The best way is to use low pressure water from the back of the intercooler/radiator however on these cars i don't think you can to many things in the way

My local gas station has free air, so ill use that to get all the leaves out every once in awhile.

if you can't get easy hands on access to the back or front of the radiator I like to spray waterless car wash or P21 Total Auto Wash through the grill onto the radiator/condenser surfaces and let sit for twenty-minutes. A weak stream of water to flush off the soap as not to push debris further inward.

I was at a self serve wand car wash (owner told me they us city water and not recycled water) and I sprayed the radiators from the outside front and I think due to the grill work and the way the wand disperses water it wasn't that strong a flow to bend the fins or driver stones further inward.

I also have a nice little grab tool from Griots Garage that lets me grab leaves from the bottom shelf in front of the radiators.

While on the subject. I use a vacuum to clean out the drain at the base if the windshield and Q-tips to clean the drain at the narrow opening the black plastic flap makes on top f the rear light cluster. Every few years I unbolt and pul pop the rear light clusters off to clean out crud and apply some spray wax to the surfaces.
