There are a few things you can do to clean a dog leash:

  1. Soak the leash in warm water for a few minutes. This will help remove any dirt, dust, and other debris that may have built up on the leash over time.
  2. Use a mild soap solution to clean the entire length of the leash. Be sure to use enough soap to cover all of the dirt, dust, and other debris that may be on the leash.
  3. Rinse the leash in cool water and then dry it off completely. Make sure to keep all of the water and soap residue away from your dog!
