Pour 1 cup of regular table salt into a container with 1 gallon of water. Place your jeans in the container and let them stay for two to three hours.
Remove the jeans from the salt water. Ring the water out of the jeans and rinse out the salt with cool water, then allow them to dry thoroughly.
Add 1/2 cup of salt to your washing machine with detergent if you prefer not to use a container. Wash and rinse the jeans as you would normally do when doing your laundry, then let them dry.
