Your leather BDSM collar will need to be cleaned if you want to preserve the life of the item, and ensure it looks and feels its best for longer. Keeping sex toys clean is important for hygiene, BDSM collars included. A leather collar is more likely to become sweaty, which can lead to chafing and discomfort if not cleaned properly. It is best to wipe down the BDSM collar with hot soapy water after use to remove surface residue; you can also access cleaning materials designed to keep a leather collar in tip-top condition for longer. It is best to match the product you use with the particular type of leather.
