Peeling price-tag stickers off newly purchased books, mugs, and binders often leaves a gummy residue behind. Scraping off the tacky adhesive with a fingernail doesn’t always do the trick, but there’s another way to remove the stickiness.
Remember the rule of thumb: “Like dissolves like”? That is, polar substances dissolve in polar media, and nonpolar substances dissolve in nonpolar media. The residue from price tags and labels is typically made of non-polar, polymeric molecules. So, nonpolar products will dissolve the nonpolar residue, which would allow you to remove it from your new purchase. For example, limonene, a naturally occurring compound in oranges, is a nonpolar organic molecule that is often used in cleaning products.
⇨ 1 part baking soda (Sodium bicarbonate, NaHCO3, as an abrasive agent; it also helps make a non-runny paste)
⇨1 part melted coconut oil (rich in nonpolar fatty acids of medium size; excellent for dissolving nonpolar goo)
⇨sweet orange oil (or other citrus essential oils)
Combine ingredients, adding just enough baking soda to the coconut and orange oils to make a paste. Apply the paste. Wait an hour or two, and peel or scrub off the adhesive!
