Reddit mentions of Turtle Wax T-520A Bug and Tar Remover, Trigger - 16 oz.

I don't know if it's "The Best Way", but after peeling the sticker from my car with the hair dryer trick I used some Turtle Wax Bug & Tar remover to remove the glue residue and it was very effective.

As an aside, I haven't tried it yet for anything else.

Turtle Wax Bug & Tar Remover has worked very well for me.

Every other Turtle Wax product I've used has been terrible but this one is actually pretty good

I always keep some bug and tar cleaner w/ a microfiber towel in the trunk for inevitable bird poop. Does a pretty good job of removal even if it has been on there for a couple days.

Take a heat gun to the badging and run some floss behind the letters and it should come right off. As for residue, use this awesome cleaner from Turtlewax. It worked for me, and I think the car looks much better.

Ugh, WD40? Guess you hate your paint. You should be using a bug and tar remover that's safe for car paint.

You can try either bug and tar remover by turtle wax (the only product ID ever buy from them), 90% isopropyl alcohol will work too, as it works great for tree sap and it's safe for clear coats, or if all else fails, you can try a clay bar with some quick detailer as lube. Mothers has a quick detailer and clay bar kit you can buy at any auto parts store like AutoZone/Advanced Auto.

I used this and followed the directions on the bottle of leaving it on for one minute.

I'll look for the remover you linked soon and hope that works, and if not, I'll try a clay bar. Thanks for your help!

Looks like bird shit. Try some bug and tar remover with a microfiber cloth.
