I mean when we go for a long drive on highway, the result is always full of flys, bees and other insects on front of our AC condenser and some of those dead insects are hard to remove with airgun so what i did is i washed the condenser with high pressure of water at local carwash which cleaned it all out. i tried using the steel brush to remove bees but that damaged the wall of the condenser since its too delicate. so my question.....is it safe to wash it with high pressure of water? or what if i just leave it alone with all the insects on it would that creat any consequences?

 

Eventually the bugs dry up and disenegerate. It seems the pressure washer would push them further into the condenser fins, I'm sure over time the pressure washer isn't good for your paint. Also the car wash water is probably well water which will leave hard water stains on your car if you don't dry it.

 

someone should develop water injection onto the condenser/radiator while running. it'll make it a lot cooler! if the pressure washer doesn't bend the fins and it's cleaning it out, it should be fine.
