Why Rope Care Is Worth the Bother

A climbing rope is one of the biggest single purchases you'll make as a climber, and unlike a cam or a harness, it has a working life measured in wear rather than in years. Ropes rarely fail because they're old. They fail because grit has worked its way into the core, because UV has degraded the sheath, or because something chemical in the boot of a car has quietly eaten into the nylon. Almost all of that is avoidable. Treat your rope well and it will reward you with years of dependable service; treat it badly and you'll be replacing it long before you need to.

When and How to Wash Your Rope

Wash your rope when it feels stiff and wiry, when your hands come away grey after a route, or roughly every six to twelve months of regular use. Dirt is abrasive, and grit trapped between sheath and core does more cumulative damage than the occasional fall.

Hand washing is the safest method. Fill a bath with lukewarm water — no hotter than 30°C — and add a small amount of mild, non-detergent soap. Never use washing powder, fabric conditioner, bleach or biological detergent: the additives and optical brighteners weaken nylon at a molecular level. Soak the rope, knead it gently along its length, and rinse.

If you'd rather use a machine, choose a front loader with no central agitator, set it to a delicate cycle at 30°C and disable the spin. Loosely daisy-chain the rope or coil it and pop it inside a mesh bag or a pillowcase to stop it tangling around the drum. Never put a rope in a top-loading machine.

• Rinse two or three times until the water runs clear.
• Don't leave it soaking for more than about an hour.
• Skip the spin cycle entirely; it crushes the core.
• Wash ropes on their own, not with clothing or your harness.

Drying Without Doing Damage

Heat and sunlight are the enemies here. Lay the rope flat, or drape it loosely over something smooth and rounded, in a cool, airy spot well out of direct sun. A spare bedroom floor with a towel underneath is ideal; a damp garage or shed is not, because chemical fumes linger. Turn it occasionally so air reaches both sides. Expect 24 to 48 hours, and longer in cold, humid weather.

Never tumble dry a rope. Never leave it draped over a radiator or in an airing cupboard. And never hang it over a nail, hook or sharp edge — a tight bend under its own weight can stress the core even while the rope is doing nothing at all.

Storing It Between Trips

Storage is where most ropes quietly lose years of life. The ideal is a cool, dark, dry place with a stable temperature, away from sunlight and anything chemical.

• Coil the rope loosely, or daisy-chain it — no tight knots, which create permanent kinks.
• Keep it away from bleach, petrol, battery acid, solvents, insect repellent and sunscreen.
• Don't leave it in a hot car boot for weeks on end, and never let it sit in a puddle of anything.
• A rope bag is perfect for crag days, but empty it out and let the rope breathe once you're home.
• Hang it on a wide, smooth peg, or store it loose in a bag — never on a narrow hook.

Habits That Quietly Shorten a Rope's Life

Standing on your rope grinds grit into the sheath and is one of the most common causes of premature wear; use a rope bag or a tarp instead. Top-roping repeatedly over the same metre of rope creates a worn, glazed patch, so vary your anchor points where you can. Running a rope over a sharp edge, even briefly, can cut the sheath and expose the core.

Be honest about falls too. A single severe fall — a high-factor fall onto a short length of rope — is worth noting. If your rope has taken one, inspect it carefully and consider retiring it even if it looks fine.

Knowing When to Retire It

Run the rope through your hands after every trip. You're feeling for flat spots, soft or mushy sections, glazing, sheath slippage and any place where the core shows through. A little fuzziness on the sheath is normal and harmless; a deep cut, a bulge or a stiff, crunchy patch is not. A rope that's been stored wet, exposed to chemicals, or used heavily for five or more years of regular climbing has earned its retirement. Mark the ends when you buy it, note the date, and you'll never have to guess. Your rope is the one piece of kit standing between you and the ground — a few minutes of care is a very small price to pay.
