Pasta from a ballpoint pen tends to eat into the structure of the paper, what can be said about a pencil. It is therefore not possible to eliminate ink by using the eraser in a mechanical way. Unwanted sign or a bad grade can only be removed with the help of special compositions. In any case, do not try to scrub the paste eraser, as at this point the paper can be cleaned thoroughly. And thus, you will not be able to hide tracks that you wanted to leave unnoticed.

Stir the composition until complete dissolution of crystals of potassium permanganate. Put the sheet on which you will remove the paste, clean white paper. Dampen a thin brush or cotton swab in the prepared solution and carefully guide her unwanted label. Do not be afraid that this place will be a spot of brown color, it can be easy to remove with a piece of cotton wool soaked in hydrogen peroxide. It remains only to dry the area of the paper with a warm iron (through a layer of material).
