How Does Lemon Juice Erase Highlighter

Lemon juice is widely known for its natural bleaching properties, making it an effective solution for erasing highlighter marks. With its high acidity and citric acid content, lemon juice can break down and lift the pigments of the highlighter ink from various surfaces. By applying lemon juice to the affected area and allowing it to penetrate for a certain period, the ink pigments start to dissolve and become less visible.

Thus, lemon juice acts as a powerful stain remover, providing an easy and inexpensive method to erase highlighter marks effortlessly.


To erase highlighter using lemon juice, follow these steps in detail:

1. Gather materials:
Collect all the necessary materials, including lemon juice, a cotton swab or soft cloth, and the highlighted text or paper.

2. Squeeze lemon juice:
Cut a fresh lemon in half and squeeze the juice into a small container. Ensure there are no seeds in the juice.

3. Apply lemon juice:
Dip the cotton swab or soft cloth into the lemon juice, making sure it is soaked but not dripping. Gently apply the lemon juice to the highlighted portion of the text, using small, circular motions.

4. Blot with a paper towel:
Take a clean paper towel and lightly press it onto the treated area. This will help absorb any excess lemon juice.

5. Assess the results:
After blotting, check if the highlighter marks have lightened or disappeared. If they are still visible, repeat steps 3 and 4 until the desired outcome is achieved. Be careful not to excessively moisten the paper, as it may damage the text.

6. Let it dry:
Allow the paper to air dry completely before handling it further. This will prevent smudging and maintain the quality of the text.

7. Optional:
If the lemon juice leaves a residue or alters the appearance of the text, you can lightly dampen a clean cloth with water and gently wipe the treated area to remove any leftover lemon juice. Remember, lemon juice may not completely remove all types of highlighter ink and its effectiveness may vary depending on the type of paper and the freshness of the lemon. It is always recommended to test the lemon juice on a small, inconspicuous area first to ensure it does not damage the text before proceeding with the entire highlighted section.
