Even better, for either climbing rope or long lengths of cordage, is to stuff the rope in a rope bag or similar. I have been doing this for years and have never had a failure to feed smoothly, either in climbing or setting up a rappel. While in the bag, your rope is well protected from potential contaminants

I understand Yosemite SAR has a 3000' rope which is stuffed in a duffel bag (with many successful deployments).
