Summarize this article:

Sprinkle baking soda over the deodorant stain and then saturate the area with white vinegar. Scrub the stain gently with a soft brush before washing it like you normally would. You may need to do this 2-3 times to fully get rid of the stain. If this is a consistent problem you see on your dark clothes, consider switching to a spray or gel deodorant. They're less likely to stain. Grab a pumice stone and rub it back and forth in a circular motion over the sections you want to make more distressed until the denim starts to shred. Once the denim begins to separate, you can pull the threads apart by hand to make the patches look even more distressed. This trick works especially well with worn-out knees. You could extend the distressed section up over your thighs, or even add a few patches to the front or back pockets. Turn the garment inside out and loosen the seams connecting the shoulders to the body of the shirt. Take in the neckline by 14 to 12 inch (0.64 to 1.27cm) on each side, depending on how widely the neckline is gaping. Stitch the shoulder seam back in place with a matching thread. If there is a lot of excess fabric left after you've sewn the seams, you may want to trim them away so they don't create a bulge underneath the shirt.
Get rid of deodorant stains on clothes with baking soda and vinegar. Distress your jeans to turn worn patches into intentional design spots. Fix a gaping neckline to refresh your favorite tops.
