WD-40
According to the WD-40 website, users of the product have found it effective against sticker residue.
Using sticker residue on cars as an example, the WD-40 website explains: “WD-40 is the ultimate go-to lubricant and did you know it can loosen the hold of sticky substances such as sticker residue?
“All you need to do is simply spray some WD-40 Multi-Use Product onto the sticker (for a more precise application, use the WD-40® Smart Straw Multi-Use).
“Once applied, let the formula sit for several minutes and then use a clean rag to wipe away the unwanted residue.”
