I use goof off. Just get a paper towel and put about a tiny half cap worth in one little spot on the paper towel and then use your index finger to rub that on the sticker residue and it’ll come right off. You’ll probably have to do it several times but it does take it off really well without pulling up the paint or finish whatsoever. I’ve done it on a ton of Macs and windows manufacturer laptops and tablets etc. Don’t use it on the screen obviously but to get sticker residue off the housing it’s completely safe won’t leave a mark whatsoever and it works awesome.
