I have a Matte B. My method is to drench the matte parts in warm water, then lay a warm soaking wet micro fiber towel over the front parts and let that soak for a while. Come back, rinse the towel, soak it again, then very gently dab the bugs away from a small area to make sure they, too, are soaking wet and come right off. You can even use the headlights as a test area. As long as the bugs are sufficiently soaked, then they come away without scratching. I dab more than wipe the first time around. Once they're all gone, then I use a second wet microfiber to wipe down and clean. Doesn't take long to air dry, then another microfiber to apply Ducky Matte finish detailer.

All sounds longer than it takes. I've done this plenty of times and so far no swirls or scratches.
