Inspect ropes thoroughly before, during, and after use for cuts, frays, abrasion, mildew, and soft or worn spots. Never step on a rope or drag it on the ground unnecessarily. Avoid running rope over sharp or rough edges (pad if necessary). Keep ropes away from oil, acids, and other corrosive substances. Avoid running ropes across one another under tension (nylon to nylon contact will damage ropes). Do not leave ropes knotted or under tension longer than necessary. Clean in cool water, loosely coil, and hang to dry out of direct sunlight. Ultraviolet light rays harm synthetic fibers. When wet, hang rope to drip-dry on a rounded wooden peg, at room temperature (do not apply heat).
