Small question

I filled my gas tank a little over. A little gas leaked onto the car, so now it has a small spot where you can tell where it leaked. I tried rinsing and cleaning it off. What can i do to fix this so it goes away? Seems as if it ruined paint, but it also seems it's an easy fix.

Wax

Try some dish soap, (with a capful of ammonia in it) rinse off and wax afterwards,,, The dish soap will remove the wax already on the car, which is what actually got "stained". If there's a stain inside the vehicle, on carpets seats etc this mix usually works on that too... I usually do my carpets with this, then pour "kitty litter" all over and vacuum it all up.
