But What Is the Blue Part of the Eraser For?

What the Experts Say

Even eraser manufacturers confirm that the blue side was never intended for ink. Its coarser texture allows for more aggressive erasing on rougher materials, but it won’t magically erase pen marks.

Some versions of the blue eraser can fade light ink on thick paper, but don’t expect it to erase it completely.

Final Verdict: Time to Let Go of the Myth

If you were one of the many who believed the blue eraser was a secret ink remover—you’re not alone! But now that the truth is out, you can stop grinding your pen mistakes into oblivion.

Use the right side of the eraser for the right surface, and your pencil marks will disappear with ease—no torn pages required.
