The used, comfortable, “worn” look of soft denim is a very popular style today. If you don’t want to let nature take its course in aging your jeans over time, and would prefer to make new jeans soft and light blue from the day you buy them, there are some simple techniques that will help you get that "faded denim” look and feel in just a few hours.
Remove all tags from your new jeans.
Wash your jeans in hot water combined with a strong detergent.
Remove jeans from the washer and blot dry with an old towel.
Fill the washing machine with two cups of bleach and set the cycle for a small load. Allow the washer to fill with water in order to completely mix the water/bleach solution.
Put the jeans in the bleach- and water-filled washing machine and allow them to soak for five minutes. If the machine starts to agitate, simply open the lid.
Pull your jeans from the machine and look at the color. If they are not faded enough, put them back in the washing machine and allow them to soak, checking the progress of the color fade every two to three minutes until you are happy with the results.
Run the washing machine through a regular cold-water cycle with the jeans in the water/bleach mix.
Run the washing machine a second time in cold water with strong detergent, and set the machine cycle to extra rinse.
Remove your jeans from the machine and, if possible, air dry in the sun to promote further fading.
If you want to further distress your jeans, use a bleach-soaked sponge to wipe random wear spots on the jeans.
If you don’t have access to a washing machine, you can use a big bucket, tub or basin for bleaching and soaking your jeans.
Work in a well-ventilated area to avoid inhaling bleach fumes. Make sure all of your clothing and work surfaces are protected from splashing bleach. Wear gloves when handling bleach and wash your hands with warm, soapy water after handing bleach-soaked jeans.
