Cleaning Bugs Off Front Cap of Suites

[BillA]

I decided to wash our suite this weekend primarily to get the bug debris off the front fiberglass cap. I was not very successful. I was using a carwash detergent and scrubbed the cap three times, first with a soft RV brush and then with a soft carwash mitt. I would guess that 50% of the bug stuff is still firmly cemented to the fiberglass cap. The only thing that will remove it is concentrated pressure and scrubbing on each individual bug which could take hours. Does anyone know of a good cleaning product that will soften or dissolve the bugs without damaging the fiberglass?
