I brought home a tall stack of new-to-me soup bowls from the thrift store and proceeded to peel off the first price sticker which ripped and shredded, leaving a half-on half-off sticky mess. What was the best way to get persistent goo off my new ceramics?
I filled the sink with warm soapy water and washed off most of the sticker paper. There was still a big round gooey area left after the bowls were rinsed and air dried. Rubbing the goo with a towel just seared it more. I tried isopropyl alcohol but the goo remained.
“What about a little WD-40?” a little voice in my head suggested. I’ve used the stinky lubricant as a solvent for grease and other persistent residues . . . no way was I spraying that toxic stuff on my dishes. Maybe an edible oil might work just as well. I put a drop of vegetable oil on the gooey area and rubbed it in with my finger, slowly the goo lifted off the ceramic and then wiped off easily with a paper towel. Vegetable oil is an excellent, non-toxic solvent for any tape residue left on solid surfaces. I bet in a pinch I could rub a greasy French fry on my dishes but for now, I’ll just use a drop of canola.
