Neutral pens are the most common kind of pens we use and come in a variety of colors, with black being the most common. In the general form, when the exam is required to use a black neutral pen. The ink of this kind of pen is oily liquid, and the strokes are relatively fine. If it gets on the clothes, it is easy to get into the fibers of the clothes, which is not easy to clean, let alone the handwriting dry for a long time. So is there any way to wash it off?
How do I wash the dry black neutral pen off my clothes
Step 1 Clean with alcohol
Neutral brush oil can be washed off after long use. Neutral pen oil is oily. You can use an oily lotion to remove stains based on similar compatibility principles. When cleaning neutral brushes, you can use alcohol lotion instead of pharmacy medical alcohol. Apply the alcohol evenly to the stain, let it sit for a few minutes, and then scrub as normal.
2. Clean with detergent
To clean long-term neutral pen oil, you can also choose detergent lotion. The detergent contains lipophilic molecules that coat oily substances and effectively remove stains from neutral pen oils. When cleaning pencil oil stains, apply detergent to the stain, wait a few minutes, scrub gently, and then wash after the stain is removed.
3. Wash with disinfectant
The neutral oil is longer and can be removed with disinfectant. The disinfectant contains a strong oxidizing component, which can decompose neutral pen oil and achieve bleaching effect. This method is completely effective, but pay attention to the amount of disinfectant and the range of use. When used in excess, it is easy to discolor clothes. In addition, it must be washed several times after cleaning to ensure clean disinfectant.
Neutral pen leakage ink on clothes how to wash
1. Alkali powder
First, soak the dirty clothes in warm water at 6°C, and then add the appropriate amount of alkali powder to the warm water. Dissolve the alkali powder in warm water and soak for about 10 minutes. Finally, remove the clothes and wash them normally to remove ink and ink.
Step 2: Flour
Mix flour and water together to make a paste. Note that the ratio of flour to water must be controlled. Then apply the prepared paste directly to the front and back of the garment refill, and place the garment in a sunny and airy area. Dry the paste and rub it directly to remove the stain.
3. Mung Bean powder
First, Mung bean powder is applied to the stain on the clothes, and then the clothes coated with mung bean powder are ironed with an electric iron. After using the iron for a while, the ink will disappear from the clothes, thus achieving the purpose of removing oil stains.
What is neutral ink
The main component of neutral ink is color based pigments (such as high quality acetylene black), and the liquid on the ink is called tail oil. The function of the tail oil is to protect the ink in the ink pipe. In addition to its sealing function, it prevents ink from backflowing, and also inhibits ink volatility and ensures good ink condition.
The viscosity of neutral ink is between water – and oil-based. Its viscosity is lower than that of oil-based inks. If you wipe hard, the ink will leak out. Moreover, if exposed to air for a long time, the solvent will gradually evaporate, making the ink thicker and harder to drain. In addition, as the liquid level drops, the ink will remain on the inner wall of the pen refill, resulting in waste.
