The methods to remove the handwriting of markers include cleaning with wind oil, cleaning with white vinegar, cleaning with toothpaste and so on.
1, clean with essential oil.
The essential balm is the most effective, because it has the functions of dissolving oily ink and washing. Find a bottle of essential balm and apply it to the handwriting of the marker. After a while, the handwriting of the marker will disappear without a trace.
2, white vinegar cleaning
If the clothes are accidentally stained with marker handwriting, you may wish to apply laundry detergent to the stains on the clothes first, rub them hard, and then wash them with water! If the handwriting is on the wall or table, you can soak it in white vinegar with a few paper towels, and then take out the paper towels soaked in white vinegar and press the handwriting several times.
3. Toothpaste cleaning
Toothpaste can remove marks from clothes. Just soak the clothes in cold water for a while before washing. If you are still worried about being unclean, you can also wipe some salt before cleaning.
The difference between marker and brush:
1, marker is fast, fast for a few seconds, slow 10 seconds; The paint pen dries slowly. Generally, surface drying takes about 3 minutes, and complete drying takes more than 30 minutes, and it has a great relationship with the temperature and humidity of the environment. If humidity is high, it may take several days to dry.
2. The marker pen is easy to use, and you can write directly by opening the cap; The paint pen comes with an ink control valve. When in use, when the pen tip is pressed, the control valve in the pen holder is opened, and the ink can only be used when it flows to the pen tip, so the use of the paint pen is more complicated.
3. The paint pen has good fixing effect and strong coverage. If it is a general complementary color, it can cover the background color and is not easy to fade. It can be used for complementary color and painting of small defects such as automobiles and parts. Relatively speaking, the fixing effect of marker pen is not as good as that of paint pen, and its hiding power is not as good as that of paint pen.
4. The price of paint pen is more expensive than marker pen, so the use cost is higher.
