If the pencil marks are shallow, erase them with an eraser. When choosing an eraser, we suggest using a professional painting eraser and try to avoid an eraser with fragrance. The decontamination effect is poor.

2. Toothpaste

If the pencil marks are heavy and the eraser effect is not great, try using toothpaste. It is suggested to choose white toothpaste without added particles inside, spread the toothpaste evenly on the graffiti, and then wipe off the stains with a dry towel dipped in a small amount of water.

3. Alcohol

Alcohol is recommended for large areas of pencil marks. You don't have to work hard to wipe it. As long as you pour alcohol on the sponge and wipe the pencil drawing repeatedly, the stains can be eliminated, whether it is a pencil drawing or a water-based pen.
