undercoating problem

I just had my car undercoated and noticed the shop must have gotten a little bit of overspray on one of my rims. I was trying to rub it off but had no luck. Anyone have an idea what I could use to get that crap off?

Try some tar remover or mineral spirits. Carb cleaner or throttle body cleaner will also work but be careful as it can damage the coating on the wheel.

Thank you, I will give it a try.
