What if black pen water gets on the sheets?

There are children at home, or you accidentally get ink on clothes or sheets. Generally, this situation is difficult to clean up. What should I do if black ink gets on the sheets?

1, rice grain. The main components of ink are bone glue and carbon black. Ink is only on the surface of sheets or clothes, so it is easily soluble in water. It is suggested to smear rice in a dirty place, then rub it repeatedly, and finally clean it with water. Because the starch in rice can absorb ink.

2. milk. Milk washing ink stains use the effect of aggregation to remove stains. Just put the milk where there are ink marks, and then wipe it repeatedly. Because milk is a suspension, ink will disperse when added to water, and demulsification will occur when added to milk, leading to flocculation.

3. Color bleach. Color bleaching can help clean paper if you accidentally leave ink marks on it. Color bleaching can help paper to remove ink without destroying the original background color of paper, which is a better method to remove ink.

4. bleach. If white clothes or sheets are accidentally stained with ink, you can use bleach to clean the sheets. Bleach has super bleachability and reducibility, which can help restore the original color.

What should I do if all the above are black pens and water get on the sheets?
