Using correction fluid line by line takes forever, especially if you want to reuse the whole page.
A hair straightener can fade certain pen inks at once, making the page usable again.
Some pen inks are heat-sensitive, which means they can fade or disappear when exposed to controlled heat. To reuse a notebook page, place a thin sheet of paper or cloth over the written area, then briefly press a hair straightener on low heat over it.
The heat breaks down the ink’s chemical structure, causing the pen marks to lighten or vanish while leaving the paper mostly intact. This works best on erasable or gel-type inks and should be used carefully: too much heat can scorch paper or damage the notebook.
