Using these hose clips is easy. Just place the clip around the hose where you need it and tighten it properly. Make sure it's snug but don't over - tighten as it could damage the hose. When installing, ensure the smooth inner part of the clip is in contact with the hose to avoid any scratches. As for maintenance, since they're made of 18/8 marine - grade stainless steel, they're resistant to corrosion. But it's still a good idea to clean them occasionally with a mild soap and water solution to keep that polished finish looking great. Keep an eye on the clips over time, and if you notice any signs of wear or loosening, it might be time to replace them. Remember, these clips come with a 12 - month warranty, so if you have any issues, you can get in touch with the manufacturer.
