I bought one to get sticker residue off my windshield, but it's proven useful many times since.
Mind, considering how well it removes glue, I wouldn't stick anything that was touched by it in my mouth... but may be okay for the hand end of your chopsticks.
Orange oil works wonders. It's explicitly not food safe, but you get that stuff on your hand every time you peel an orange and it's also present in juice. Just rinse them afterwards and wear gloves.
I recommend isopropyl alcohol. It’s cheap, versatile and works like a charm for most of your cleaning jobs. Way safer and cheaper than sprays and "super-do-that-thing-4000". No offense to the sprayers.
