How to wash jeans in three basic steps？

Once considered basic, durable work attire, jeans now come in a huge range of styles and colors. While you should always check your care instructions before washing or drying jeans, there are a few simple steps that apply to all types of denim.

Step 1. Use a delicate or gentle cycle
Denim may seem like a tough fabric, but that doesn’t mean you should choose a heavy-duty wash cycle. Instead, opt for a delicate or gentle cycle, and use cold water to avoid shrinking or fading. Opt for a mild detergent, especially one made specifically for dark clothes if your jeans are blue or black. 

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 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 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.
 
Cleaning tip: Washing clothes by hand can be a great way to maintain the integrity of material over time, whether you’re washing a baseball hat, delicate laundry, or even your jeans.
