We all want our favorite jeans to last forever, and luckily for us, there are some ways in which you can make them even much more durable. Use a proper detergent. Some detergents include bleach, and of course, you will want to avoid any of those. The best detergents for jeans are the ones specifically made for darker clothing. That way, the dye won't rub off. Turn the jeans inside out. You see, the part that needs washing is the one that is in contact with your skin. Besides, doing it this way will protect the exterior of the fabric. Wash your jeans with any other dark type of clothing. If you wash your pair of jeans with lighter items, you are at risk of ruining them. If you can, use a gentle cycle. Today, most machines have a gentle cycle. However, if you don't have one, the best you can do is to wash the jeans by hand.
