How To Erase Marker?

Sometimes I accidentally mistake the marker pen for a whiteboard pen and write on the whiteboard without falling off, or write something else that is difficult to erase. If you write on a smooth surface or a whiteboard, you can use a whiteboard marker (in the company They are usually kept) and trace it over the original marker again, and then use paper or even a damp cloth, which can be wiped away. If there are traces, you can try a few more times. As for the principle, I can also share it with you, because Whiteboard pen inks all contain alcohol, and most markers can be dissolved by alcohol. This is what is learned in chemistry: similarity equals compatibility.
If you don't have whiteboard markers, there are many other ways to remove them. You can use alcohol (if available), or nail polish remover. Nail polish remover is actually very effective at removing all kinds of markers, and more than 90% of them can be used. The reason why it was wiped off is because the nail polish remover contains acetone, and the solubility of acetone is relatively strong.
But if it is written on clothes, it will be a little more troublesome. You can use 84 disinfectant for white clothes. Colored or dark colors will not work. You can also use nail polish remover to wipe a small amount on clothes. If there is a lot, you can buy a small bottle of industrial alcohol online. It can also be removed by washing.
