For those fresh pairs of jeans, hold off on washing them with detergent in the first wash. Check out these tips from Mytour below to keep your jeans looking as good as new.
Freeze your jeans
Before the first wash, place your jeans in the freezer compartment to help preserve their color. Then, soak them in a solution of cold water mixed with a generous amount of salt, vinegar, or lemon juice for at least 12 hours. Finally, rinse with clean water and use as usual. Note: Avoid using bleach to wash your jeans for the first time.

Shortening the freezer time helps jeans last longer
For jeans, it's best to hand wash them as machine washing can cause the color to fade and the fabric to age faster. Remember to never use fabric softener with jeans as it can soften the fabric, making the jeans lose their shape and fade.
If you prefer using a washing machine for jeans, make sure to manually clean any dirty spots first, then turn the jeans inside out before putting them in the machine. The spinning pressure of the washing machine as well as the water temperature can cause the jeans to lose color. Therefore, choose the lowest spin cycle and temperature to maintain the color of your jeans.
Soak jeans in a saltwater solution
This hack is incredibly simple to do, just pour a sufficient amount of salt and water into a basin, then soak your jeans in this solution for about 5-10 minutes, then wring them out by hand.

Salt helps maintain color and shape for jeans
Salt stabilizes the color, making jeans last longer and maintain their shape better than usual. The most basic way to keep jeans from fading and wearing out is to not wash them too often and wear them at least twice before washing.
You can't wash jeans when they're dirty and starting to smell, use the following hack to clean them. Mix ½ water with ½ alcohol and pour it into a spray bottle, then spray this solution onto the jeans, especially the dirty areas, then put the jeans in the freezer overnight. The next morning, you'll be amazed at how much the smell on the jeans has noticeably reduced.

Turn inside out and use clips when drying jeans
How to dry jeans
You should dry jeans in a well-ventilated area, under a shelter and avoid direct sunlight. Due to the intense rays of the sun, jeans are prone to fading. Note that you should turn them inside out before drying and use clips to hang them on a line or use hangers with clips. Using regular hangers to dry jeans will cause them to wrinkle and lose their shape. If you use a dryer to dry jeans, dry them at the lowest temperature.
With the tips in the above article from Mytour, hopefully, you can keep your favorite jeans colorfast and longer-lasting.
