How to erase with a marker? This is the most common problem that everyone encounters. The marker is written on the whiteboard or on the clothes, and it cannot be erased if you want to erase it. Here I have some tips to recommend to you.
Sometimes it is accidentally written on the whiteboard as a whiteboard pen, or it is difficult to erase when it is written on other things. If it is written on a smooth surface or a whiteboard, you can use a whiteboard pen (in the company). Generally, it is always available.) Trace it again on the original marker, and then use paper or a damp cloth. It is better to wipe it off. If there are traces, you can try a few more times. As for the principle, I can also share with you, because Whiteboard pen inks all contain alcohol, while markers are mostly soluble in alcohol. This is the similarity that is learned in chemistry, that is, compatibility.
If there is no whiteboard pen, there are many other removal methods, you can use alcohol (if you have one), or nail polish remover. In fact, nail polish remover is very good for removing all kinds of markers, and more than 90% of them can be used. The reason is that the nail polish remover contains acetone, and the solubility of acetone is relatively strong.
But if it is written on the clothes, it will be a little troublesome. White clothes can be used with 84 disinfectant. Color or dark colors will not work, and a small amount of clothes can also be wiped with nail polish remover. If there is more, you can buy a small bottle of industrial alcohol online. It can also be removed by washing. In addition, most of the marks of Mr. Wei Meng can also be removed. The inorganic acid of "Mr. Wei Meng" is hydrochloric acid (HCl), because hydrochloric acid is a strong acid, and it is easy to hydrolyze esters.
