What gets the bugs off?

[Jgntch]

I know I read a thread about this, but I have searched several different terms and just can't find it. After putting about 1,000 miles on our new-to-us camper the last few weekends, we have quite a large insect collection on our front face. Someone(s) mentioned some cleaners that they spray on and let sit to make it much easier to get everything off. She was waxed this spring, so we don't need to rewax before covering for winter, but we do want to her clean again. Suggestions for first timers so we don't ruin her looks?

Thanks,
Jackie
