How to remove ink from white paper

Let's see what ink it is. Different inks, different formulations.

If it is pure blue ink, it will be much simpler. When I was a child, I used fixing powder for developing films in a printing shop. Remember, it's 20 cents a pack, at random ratio 1: 10, and it turns into water. In this way, facing the pure blue ink, you can disappear immediately, as if you had never written it! !

If it is blue and black, on this basis, there is also a formula of licorice. There seems to be something else. I remember playing this in primary school:)

With the first sip of water in front, put it in a pen and write, and you can't see anything. However, the word "diving" comes out on a cotton swab coated with blue ink, which feels so interesting.

When you say blue, it is estimated that it is not pure blue ink, but blue-black ink. There are many formulas, so I don't remember them now:)

After the modified place is dry, use a proper eraser, because the potion is still there and has not lost its effect. Write without processing, and the words will disappear immediately:)
