Someone used a silver gel pen and drew a squiggle on my car window. Any thinking how to get it off please?
Turps (white spirit) i know it sounds strange but try hairspray


Just some hot soapy water and a used kitchen scourer. Gently rub in a circular motion. Make sure the scourer is resourcefully used so it wont scratch and dont keep rubbing contained by one spot keep going over it from left to right. Should work a treat Nail polish remover, but don't acquire it on the car cos it rips paint off
Answers:    Have you tried regular river?

The gel ink is water-based, so this should work.

If it doesn't, try rubbing alcohol, or acetone (nail polish remover).
