The safest method for removing stickers from surfaces like a refrigerator or bathtub is to use a solvent such as acetone. When used properly, solvents can break down the adhesive that holds the sticker in place, allowing for a clean removal without damaging the surface underneath. It’s important to use the solvent in a well-ventilated area and to test it on an inconspicuous spot first to ensure it does not damage the finish of the appliance or tub.

Using a hairdryer can also be effective but may not provide the same level of efficacy on tougher adhesives, and the heat may not always reach the adhesive's melting point to loosen it completely. Scraping can risk scratching or damaging the surface, particularly on delicate finishes. Using hot water may help soften the adhesive; however, it requires prolonged soaking and may not be as effective for all types of adhesives. Thus, while these other methods have their merits, a solvent like acetone provides a more direct and effective solution for sticker removal.
