Another method is to clean the ink with toothpaste. Using toothpaste can clean the ink on jeans. Don't use transparent toothpaste, just use ordinary toothpaste. Apply toothpaste to the ink-stained part, then brush it with an unused toothbrush, and then rinse it with clear water.

Basic washing methods of jeans:
1, dark jeans can keep their original color by soaking them in white vinegar+water (white vinegar: water, 1: 20) or salt water for about 20 ~ 30 minutes before the first pass.
2, dark and light colors are washed separately: mixing together will cause color mutual dyeing.
3. Do not use bleach. Wash with blue particle detergent without enzyme, because the detergent containing enzyme has bleaching effect and affects the color of jeans.
4. Avoid direct sunlight: Direct sunlight will cause serious oxidative fading.
5, drying in a ventilated place: no ventilation will make pants not easy to dry and will produce odor.
6, try to backwash, anti-sun.
7. Hand washing jeans, try not to use washing machines and brushes, which can effectively maintain the true color of jeans.
