Your climbing rope won’t last forever. If you follow these tips, however, you can increase the service and life of your climbing rope.
Don't Step on Your Rope
Besides climbing and lowering, nothing wears out your rope faster than stepping on it, especially if it is lying in sand or on the ground. Besides possibly cutting the sheath on rocks underfoot, stepping on the rope also grinds dirt and dust into its sheath and core, which increases unseen internal damage to the rope. At the cliff base, especially if you have a bunch of newbies with you, impress upon them the importance of not stepping on your rope and damaging their life line. Show some respect brotha!
Use a Rope Bag
Use a good rope bag that unfolds into a spacious tarp for your precious climbing rope to lie on at the base of the cliff. A good rope bag keeps dust and dirt from finding its way inside your climbing rope. Dirt and flecks of rock impairs the strength, safety, and performance of your rope. It wears it out faster too. A rope bag increases the life of your climbing rope. Buy one and use it. Most rope bags also neatly fold up and can be carried over your shoulder with a strap or secured to the top of your pack when you are hiking to the crag. It is especially important to use a rope bag at popular cliffs, like Shelf Road, Wall Street, or New River Gorge, where lots of other climbers stand around, leaving fine pulverized dust on the ground, or at sandstone climbing areas where lots of sand blankets the ground below the routes.
Run Your Rope Freely
Make sure your climbing rope runs freely whenever possible. There’s nothing that will trash a rope like sharp edges or rough corners. If you’re leading a pitch, use lots of slings to keep the rope well away from the cliff face. If you’re top-rope climbing, make sure that the master point that the rope is looped through is extended well over the edge of the cliff. Also remember that a fall onto a sharp edge can seriously damage or slice through a climbing rope.
Switch Ends After Falling
If you climb a lot of sport routes, alternate which end of the rope you use to lead and fall on. Avoid taking frequent falls at the same end of a rope if you’re working it. Falls stretch the rope out and slowly damages it. Switch ends and allow the rope to become more elastic and stretchy again. Also allow your climbing rope to take a rest if you’ve taken a big whipper or fall on it. Alternating rope ends will prolong its life.
Washing Your Climbing Rope
When your climbing rope gets dirty, you need to wash it. Washing your rope increases its life by getting abrasive dust out of the sheath. Washing also helps the handling of the rope. If you climb a lot, aluminum oxide is deposited on a rope’s sheath from running through all aluminum carabiners. Your hands get filthy black from the oxide just by belaying. Regular washing pf your climbing rope helps alleviate that black-hand syndrome and keeps your cord looking new.
How to Wash a Climbing Rope
To wash a rope, I put it in a large mesh bag and seal the top with a drawstring. Pop it in the washing machine and wash it in cold water on a long cycle without detergent. Afterwards, I take the rope out and drape it loosely in a washbasket and let it air dry in a cool dark place for a few days. Don’t put the rope in sunlight to dry. Some folks use a mild non-detergent soap to wash their rope.
