When installing, check that the smooth inner surface of the clip is in full contact with the hose to protect it. As for maintenance, these clips are made of 18/8 marine - grade stainless steel, so they're quite resistant to corrosion. But in harsh environments, it's a good idea to clean them occasionally with a mild soap and water solution. Dry them thoroughly after cleaning.
