Permanent markers are difficult to erase in most cases because the ink is designed to leave a long-lasting, non-fading mark on a variety of surfaces. However, it is possible to remove or lighten permanent marker marks with some specific methods and tools. Here are some things to try
Using alcohol or acetone:
Alcohol, especially isopropyl alcohol, is an effective solvent that can dissolve some of the oily substances in permanent markers.
Pour the alcohol onto a clean cotton swab or cloth and gently rub the marker marks.
Acetone (such as the ingredient in nail polish remover) has similar dissolving power, but be careful of its volatility when using it.
Using toothpaste or baking soda:
The abrasives and detergents in toothpaste can help remove marker marks from some surfaces.
Apply toothpaste to the mark and gently rub it with a damp cloth or toothbrush.
Baking soda can also be mixed with water to form a paste and used to wipe the mark.
Using an eraser:
For some smooth surfaces (such as glass, metal, etc.), using a harder eraser may help erase marker marks.
However, erasers may not be as effective on rough or absorbent surfaces.
Using a whiteboard marker or dry erase pen:
In some cases, repeatedly smearing over the marker mark with a whiteboard marker or dry erase pen and then quickly erasing it may help remove the mark.
This method takes advantage of the interaction between the solvent in the whiteboard marker or dry erase pen and the marker ink.
Using a professional cleaner:
There are some cleaners on the market that are specifically designed to remove marker marks. These cleaners usually contain special chemical ingredients that can remove marks more effectively.
Before use, be sure to read and follow the instructions for use of the cleaner.
Other methods:
You can also try using products such as wind oil, floral water, sunscreen, hand soap, clothing stain remover to wipe the marker marks.
For marker marks on clothing, you can use 75% medical alcohol plus soap to clean.
It should be noted that the above methods cannot guarantee complete removal of permanent marker marks, and the results may vary depending on factors such as ink type, stain age, material, etc. Before trying any method, it is recommended to test it in an inconspicuous area to ensure that no damage will be caused to the marked surface. If the mark is very stubborn or covers a large area, you may need to seek the help of a professional cleaning service.
