Unfortunately, those who like to spend a couple of hours with a book from time to time encounter such a problem as the appearance of mold on the pages of a printed publication.
There are two reasons for this unpleasant phenomenon.
One of them, the most obvious, is the high humidity that reigns in the room where the volumes of favorite authors are stored.
The second factor that negatively affects the condition of books is related to constant temperature changes.
In addition to the appearance of mold, the pages can become a source of unpleasant odor - you must admit, you will not be able to enjoy an interesting story in such conditions.
That is why, no matter what the problem is, it requires an immediate solution.
A reliable assistant in such a situation will be ordinary soda. Place the book in a paper bag and sprinkle the pages with a small amount of baking powder.
Let the encyclopedia or detective story lie like this for a couple of days, then shake the soda off the books and leave them in the sun for a day.
