Recipes for removing ink
Here is a recipe that allows you to remove printing paper, stamps and other records from writing paper.To obtain this liquid, it is necessary to take 70% acetic concentrate (about one teaspoon) and a small amount of potassium permanganate in crystalline form (at the tip of the knife). These substances are mixed, and after that the liquid is ready for use. Under the piece of paper from which you want to remove something, you must put a blank white sheet of paper. Then take a brush (the softer and thinner its hair, the better for work) and, dipping it into the prepared solution, begin to draw the brush with the inscription until the inscription disappears. At this point, the paper will turn brown, which needs to be removed with a piece of cotton dipped in hydrogen peroxide solution. Then a piece of paper wetted with a solution should be dried by ironing it with a warm iron. To do this, take a soft matter, it puts a blank white sheet of paper, and already on it the paper with which the inscription has just been removed.Then it is ironed (the surface of the iron must be clean).
Note: in this way it is desirable to remove the inscription only from thin sheets of paper. To remove the inscriptions from thick sheets, it is more expedient to use a match instead of a brush, on the sharp end of which a small piece of cotton wool is wound (there are several such match brushes, since they quickly fail). Matches brushes moistened in a solution and careful reciprocating movements on the label remove it.

Recipe 2: Take 10 g of hydrochloric acid, 10 g of salt, 30 ml of water. All this stir and apply as the previous two tools.
