The ink of permanent markers does not necessarily stay on clothes forever, but it is indeed difficult to remove by conventional washing methods. This is mainly because the ink of permanent markers contains oily or resin components that are not easily soluble in water, and these components form a more durable attachment on the fibers of clothing.
Specifically, oil-based pen ink is mainly composed of pigments, binders and solvents, among which the binders and solvents are mostly oily substances, which makes the ink form a relatively strong film on the clothes, which is difficult to be decomposed by detergents and water. Permanent markers use a more durable ink formula, usually containing special resins or dyes, which form a more durable attachment on the fibers of clothing and are not easy to fade or fall off even after multiple washings.
However, although the ink of permanent markers is difficult to remove, it does not mean that it cannot be removed. In actual operation, you can try to use organic solvents such as alcohol and acetone to dissolve the ink, or use some detergents that are specially designed to remove oily stains. In addition, you can also seek professional cleaning services and use professional equipment and detergents to remove ink.
It is important to note that when attempting to remove permanent marker, you should first test a small, inconspicuous area to ensure that the cleaning method you choose will not damage the garment. Also, different cleaning methods may be required for different types of garments and stains.
