How do you remove spray paint from the buttons of the parking sensors?

Take a Q-tip and use laquer thinner,in a well ventilated area and,gently go in a circular motion.You may have to make more than one attempt,but I think you will achieve your goal,very easily.

never use laquer thinner on a sensor,it will mess them upuse a damp cloth rag (water) and clean them,the paint will come off,but if they are just painted on outside of sensor,it is not affecting them.
