How to wash off a black water-based pen

I believe that everyone must have had black water-based pen ink stains on their clothes when they were in school. If the oil stains of the black water-based pen are on clothes, it is very difficult to wash them off. Many children will be scolded by their parents for this. If they cannot be washed off, it will be a waste of a piece of clothing. In fact, it is very simple to wash off the oil stains of the black water-based pen. You can add some alcohol solution, but it must be in moderation. The following is a detailed introduction to it.

2. Ink stains: Mix rice grains and detergent, apply it to the stained part and rub it, then rinse it with clean water; you can also use a solution made of one part alcohol and two parts soap to apply it repeatedly, which also has good results.

3. Ballpoint pen stains: First, you need to check what material the clothes are made of. The general practice is to put a towel under the stain, use a small bristle brush dipped in alcohol to gently scrub it. After the stain has dissolved and diffused, soak the clothes in cold water, apply soap and gently scrub it. Repeat this two or three times and the ballpoint pen oil can be basically removed. If there are still a small amount of residues after washing, you can remove them by soaking or boiling them in hot soapy water. This method can be used for cotton and cotton-polyester fabrics. If the woolen material is stained with ballpoint pen oil, first soak the stain in a mixed solution of trichloroethylene and alcohol (in a ratio of two to three) for 10 minutes, while constantly brushing it gently with a brush. After most of the oil stains are dissolved, wash it with low-temperature soapy water or neutral laundry detergent.

4. Mildew stains: wipe with 2% soap and alcohol solution, then wipe with 3%-5% sodium hypochlorite bleach or hydrogen peroxide, and finally wash.

6. Wool sweaters are contaminated: dissolve neutral soap liquid in boiling water and add a tablespoon of borax. When the temperature drops to 60 degrees, soak the wool sweater in the soap liquid for three or four hours. Then gently rub it in warm water of 40-50 degrees, and finally rinse it with warm water. If there are still some stains that cannot be washed off, you can use soap solution and two tablespoons of turpentine to make an emulsion for washing. After washing, let the sweater dry naturally. When it is mostly dry, you can use a not too hot iron through a layer of cloth to iron it dry and flatten it, and then hang it in the sun for a while.

7. Blood stains: Fresh blood stains can be soaked in cold water for a few minutes, and then washed with soap or alcohol. If it is an old stain, you can use lemon juice and salt water to remove it, or you can wipe it with white radish, but avoid washing it with hot water. You can also use clean water to wash the blood stains until they turn light brown, then wash them with glycerin soap, and finally rinse them in warm water.

8. Chimney oil stains: If there are chimney oil stains on clothes, immediately wipe them with gasoline (wipe from the outside of the stain inwards to avoid the stain from spreading) or wash with warm soapy water.

9. To remove wax paper and carbon paper stains on clothes: first wash with detergent, then wash with gasoline, and finally wipe with alcohol.

11. Washing egg stains on clothes and tablecloths: Clothes, especially tablecloths, often have egg stains. First soak the tablecloth in cold water, then wipe it with cotton cloth or cotton cloth dipped in a little salt, and finally wash it with warm water.

12. Lipstick stains: Lipstick stains on light-colored clothing can be washed off by first soaking it in gasoline and then scrubbing it with soapy water.

13. Chewing gum stains: For chewing gum stains on clothes, walls or other items, you can first use cotton or a cloth soaked in white vinegar, and then use it to scrub the stains.

14. Tung oil stains: First soften the tung oil stains with gasoline, and then scrub them with tofu dregs to remove them completely.
