To clean your leash, soak in warm soapy water, gently clean with a towel or sponge, rinse and dry. Always rinse your leash and hardware with fresh water after a beach trip. Store your gear dry and in an area out of the sun (to reduce UV damage) with good ventilation.
To keep your brass clip working well, periodically clean and then add a few drops of penetrating oil such as WD-40 into the clasp/spring mechanism and open and close multiple times to help clear gunk.
Brass hardware will not rust but may develop a patina over time (can be cleaned/polished); black hardware will show cosmetic wear over time and/or rust if stored wet.
