For our active/adventure gear we recommend soaking in warm water. For tougher stains, grab an old toothbrush with some soap (Dawn works great) and scrub away! If there are any stains, treat the area with Shout and scrub through it again with soap. After that your collar/leash should be as good as new.
Our BioThane gear is a piece of cake to clean. Just rinse with water and, BOOM, it's as good as new. BioThane is amazing and is extremely easy to clean in just a few minutes.
For fabric collars & leashes, we recommend washing by hand would be the best for a long-lasting collar. If you need to put it in the washer please use a laundry bag or sock (to protect your hardware) and on a delicate cycle. Lay flat to dry indoors. All fabric gear will have regular wear & tear. Just like if you wore the same cotton shirt every day. If you are looking for something more durable, please check out Active/adventure gear.
