Jeans must be treated with some basic color retention before washing, otherwise they will be washed white soon. In fact, color retention treatment is very simple. Soak the jeans in a basin before washing, then add two spoonfuls of white vinegar and salt and soak for about half an hour, so that the color fading of jeans will not be so serious. In addition, reducing the times of washing jeans is a simple way to keep pants fresh, shape-keeping and durable.
1, cut a small piece of soap with a knife.
2. Pour warm water to melt the soap and stir well. Never soak denim clothes in hot water, which will cause a great degree of shrinkage. Just keep the water temperature at about 30 degrees.
3. Soak jeans in soapy water for two minutes to remove the floating color that is easy to fall off the surface.
4. Wash your pants with clean water.
5. Put another pot of warm water.
6. Add a spoonful of salt, which is volatile and enhances the penetration of pigment molecules into the fiber to achieve color fixation (to prevent fading).
7, add a little vinegar, add vinegar to prevent fading because the dye is unstable under alkaline conditions and relatively stable under acidic conditions. But the amount of vinegar should not be too much, otherwise it is easy to dye light-colored clothes.
8. Soak the back of jeans in the mixed solution for about half an hour to keep the original color of jeans, and then wash them regularly.
9. Wash jeans with water. It is not advisable to use a dryer. Just turn them over and dry them.
10, jeans should be hung in a cool and ventilated place.

Basic washing and maintenance 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. Wash dark and light colors separately: mixing them together will cause color cross-dyeing.
3. For jeans that are not too dirty, wash them with detergent. Try not to use washing powder or bleach.
In addition, please turn the jeans upside down for cleaning, which can effectively prolong their life.
5, drying in a ventilated place: no ventilation will make pants not easy to dry and will produce odor.
6. Wear dark cotton jeans about 3 to 5 times or wash them once a week. Light color: white, khaki and camel depending on the stolen goods.
