If the surface is flat enough, start with a scraper. One of those single edged replaceable blade deals. That’ll quickly take off 90%, if not all of it. If the blade gets sticky and you want to made another pass, wipe it off with some oil (basically any, even olive oil). Then go for the other suggestions, like rubbing the sticker with oil and alcohol.
This works much quicker than just oil and alcohol, BUT the surface has to be flat. If it isn’t flat, it has to be non-razor-blade-damage-vulnerable material.
