Is there a way to remove sticky residue from appliances; i.e. labels?

CITRUS KING
M1 adhesive remover
3 M adhesive remover

And dozens of other brands and types. I think I have one called goop or something like that I buy at walmart. There are several choices at most stores like walmart or home repair shop

Try heating with a hair dryer, then use rubbing alcohol or try what fr chuck said.

If your thrifty or like me and loose the bottle of goop, try dawn dishwashing liquid, vaseline, or even hair conditioner, depending on how much glue is on the appliance, use a plastic dish scrubber.
