I use the Pinnacle bug scrub sponge and Poorboys Bug Squash; purchased from AutoGeek and it works great. We have love bugs down in here which will eat through your clearcoat if left on for a few days, and they will absolutely cover your car (see picture of my old CTS-V below)
After I do an initial wash; whatever is left on the front end, I've got a separate "bug bucket" with this sponge and diluted solution of this cleaner.
