Jeans are a wardrobe staple for many people. Made of denim, a strong cotton weave, jeans are comfortable, sometimes fashionable and often rugged. Jeans stain just as any other natural fabric, and cotton absorbs and holds onto stains tightly. You can remove most stains from jeans with simple laundry products combined with using the correct water temperature–so you do not set the stain.
Step One
For bloodstains, pour 3 percent hydrogen peroxide on the stain and let it bubble. For other stains, dampen the stained areas with tepid water and apply a color-safe, prewash stain product (stick or spray) to the front and the back of the stain.
Step Two
Work the stain-treatment product into the stain with a brush. You can do this with bloodstains too. After the peroxide stops bubbling, rinse the area with cold water (warm or hot water can set bloodstains) and apply a prewash stain remover, then brush it in.
Step Three
Allow the product some time to work on the stains before you place the jeans in the wash. These products indicate on their labels the amount of time you should wait. Typically, the wait is about 15 minutes.
Step Four
Place the jeans in your washing machine and allow it to fill with water. Use only cold water if these stains are from blood or protein-based foods; otherwise, use warm (not hot) water. Add liquid laundry detergent and allow the jeans to soak for 30 to 60 minutes.
Step Five
Remove the jeans when the cycle is finished and hang them to dry. If any stain remains, repeat Steps 1 to 4. In some cases, you may need to repeat this process several times, especially if the stain is not fresh.
