Mark elimination method
According to the pigment of marker pen, it is generally divided into three types: oily, water-based and alcohol. Oily pigments can be diluted with toluene, which has strong permeability. Especially suitable for sulfuric acid paper in tracing paper, which can be removed by butyl ester and essential oil. Water-based pigments are soluble in water and are usually used for painting on cardboard or coated paper.
Remove by diluting with water or washing and drying. Alcohol pigments and volatile inks containing dyes, denatured alcohol and resins should be used in well-ventilated places. Prepare clean dust-free cloth and alcohol.
Then open the bottle cap of alcohol, put the blue bottle cap on the dust-free cloth and pour out a little alcohol. Fold the dust-free cloth into a small rectangle and the size of the bottle cap, and then put the dust-free cloth into the alcohol bottle cap for soaking. Spread a dust-free cloth dipped in alcohol on the oily pen marks on the desktop. Wait a minute or so, then gently wipe it with your hands, and you can easily remove the marks of the marker.
