Key Takeaway
To remove a sticker and sticky residue from cardboard without damaging the box, warm the label gently with a hair dryer, peel it back slowly at a low angle, then rub remaining adhesive with a clean white eraser; if needed, dab a tiny amount of isopropyl alcohol on a swab only after testing a hidden spot. Do not soak cardboard, scrape it with metal, or apply oily removers that can stain the fibers. Work from the sticker's edge toward the center, pause if printed ink lifts, and let any treated area dry flat. Gloss-coated boxes tolerate gentle cleaning better than raw, porous cardboard.
