Wish I knew about this earlier! Grandfather told how he got rid of twos in his diary during his school years

Last week I went to visit my grandfather. As usual, he brewed his signature tea and put on the table acacia honey from his own apiary, which I just adore. After talking about pressing matters, the grandfather began to recall his school years (this was in the distant 60s) and he asked to bring his graduation albums, which were in the living room closet.

Dripping in the closet, in addition to albums, I found my grandfather's school diaries. After flipping through a few diaries, I asked: "Grandfather, so you were an excellent student?" He smiled and replied: "I studied really well, but still there were times when I was given deuces and, so that parents would not know about it, I skillfully washed deuces so that they did not remain trace! ". And then my grandfather told me the clever way he used to remove ink from paper in Soviet times.

Now I will share this method with you, and for an illustrative example I will take my daughter's old diary, in which there are just a few twos.

And so, when the grandfather received a deuce or a record of bad behavior, then when he came home, he immediately went to the kitchen and took out acetic acid from the cabinet.

Then he went into the room and took the most ordinary potassium permanganate from the first-aid kit.

When all the necessary ingredients were collected, the grandfather began to chemistry. First of all, he poured a small amount of acetic acid into some container and added potassium permanganate there, literally at the tip of a knife.

Then he waited for the potassium permanganate to completely dissolve. In this case, the grandfather said that there is no need to be afraid to put a lot of potassium permanganate, the color should turn out to be very saturated.

When the solution was ready, he put the newspaper, folded in several layers, under the page of the diary. Then I twisted cotton wool on a match (I’ll use a regular cotton swab), dipped it into the solution and with neat movements (not rubbing, but as if blotting) applied it to the place with an unwanted assessment or inscription.

The ink from the red ballpoint pen disappears before our eyes. Only a pinkish trace of the potassium permanganate itself remains on the paper, which can be removed as easy as shelling pears.

To get rid of traces of potassium permanganate, you need ordinary hydrogen peroxide. Two drops and there is no trace.

At the very end, when the sheet dried out a little, the grandfather smoothed it with an iron. Voila! And the deuce, as it never happened! Oh, what a pity that I did not know about this method when I was in school myself.
