Sherwin Williams product:

Shur Will Clean, or something like that.
it is the first step i used after sanding a car before paint.
This stuff removes just about anything except paint and clear coat.
it leaves a haze so you can see it is there.
When removing stickers and such, spray it on, wipe with clean rag, terry cloth is best. repeat as needed and always keep using a clean section of rag.

Let dry to haze, little bit of rubbing compound, wax and buff.

Goo Gone works well also Oops and I have had luck with mineral oil.
