How do you fix velcro when it wears out?

To fix worn-out Velcro, first clean both the hook and loop sides with a lint roller or a soft brush to remove debris and lint that may be affecting their grip. If the hooks are flattened, you can try gently combing them with a fine-toothed comb to restore their shape. If the Velcro is too worn, consider replacing it entirely by sewing on new strips or using adhesive Velcro patches.
