I don't have trouble poking a toothpick or paperclip into the fins of my '90 Prizm AC radiator to clean out the dirt. This pushes the fins from side to side but it doesn't straighten out the ones that are turning sideways to the airflow. Is there good tool to straighten them out.? Needle nose pliers are too big. I was thinking about forceps, like those that are used in electronics work to hold parts.
