1, with pen cleaner, which can be bought in art shops. Wipe it with a paper towel dipped in a small amount of pen cleaner, and it will be easily wiped off.
2, with an eraser, suitable for removing small traces of glue marks, but it needs patience. It will turn black at first, and then clean it slowly.
3. Wipe it with a paper towel dipped in alcohol (preferably with industrial alcohol, or without medical alcohol), and then rub it a few times to clean it.
4. Use nail polish remover. Usage is the same as alcohol acetone. The effect is also very good. Nail polish remover doesn't require quality, it's good and ordinary, as long as it can wash off nail polish.
