Bug removal from acrylic finish

I use damp used dryer sheets. Works for me.

I like Zep but I wax afterwards.

I use bug melt. I use it on aircraft too (it was designed for aircraft).

Hitting them with a hose after the dew has settled on it in the AM takes a lot of them off.

Soak a towel in HOT water and lay it on the surface. Leave for about 20-20 secs and bugs will wipe right off. But it may as well remove wax.

Alternatively, spray with a 50/50 soluntion of drug store peroxide and water solution. The peroxide will attack the protein in the bugs and foam up, just like it does when you put it on a cut. This will soften the bugs' shell and allow them to be removed easier - used it on my motorcycle windshield all the time. Peroxide will not harm your paint.
