Step 1. Use a delicate or gentle cycle
Turn them inside out, and either washed them in cold water in the sink or in the bathtub, where they can be placed down flat. After you’ve washed your jeans, make sure you rinse them thoroughly with cold water, so all the suds are washed out and the water runs clear, and then hang them up to dry.
Step 2. Wash jeans inside out and by themselves
Turn your jeans inside out when washing them to help protect the fibers on the outside of the jeans from friction and direct exposure from detergent, which helps prevent fading. However, it’s not rare for jeans to bleed dye, especially if they’re new. Before you toss your jeans in the laundry, read the care instructions to see if you should wash them separately at first. If you must wash your jeans with other clothes, try to wash them with similarly colored jeans or clothing.
Step 3. Hang your jeans up to air dry or use a no-heat cycle
Exposing your jeans to direct heat in the dryer can shrink, fade, or yellow denim, and it can also cause damage to stretch denim fabrics that contain spandex or Lycra. If you need to use a dryer, select a low or no heat cycle and use dryer balls to keep your jeans tumbling. The best way to dry jeans is by hanging them up to air dry:
Remove the jeans while they’re still slightly damp, then stretch the seams and hang them up to finish drying. Once they’re completely dry, you can hang or fold your jeans
to store in a drawer or on a shelf.
