The personalized slogan on the car glass cannot be removed

You can first rinse it with water

Then try to tear it off with your hands

Or carefully scrape it off with a razor blade

Then apply it with wind oil or the like

This will eliminate some of the glue

Then Then wipe it clean with a rag

If there is still some stain after repeated several times

Use a razor blade to slowly scrape it clean
