Very aggressive wasps made a nest overnight in the rollover bar, entering through the small holes for accessory mounts. I sprayed the hole from a distance and they've moved on or otherwise are no longer a problem. However, I am unsure how to clean out the residue which seems to be petroleum-based and has warnings about paint damage. I've rinsed out what I can with soap and water. There seems to be no way to get a brush or wire down in the hole to remove the nest. Any suggestions?
