Brand new rope has unexplained blue/black stain.
|
I just bought a rope, while I was unpacking it, I noticed a dime sized black spot. Under strong light I could see that it was actually dark blue and appeared to consist of a powdery residue as well as staining of the fibers. I really want to identify a reasonable explanation for the stain before using the rope. It is a dry treated Edelweiss if that matters. |

If you want to return it, now would be a good time. It is probably a dye issue, which wouldn't cause any concern. If it is actual chemical damage, you will be able to peel off the damaged nylon strands. |
|
Did you contact Edelweiss? |

My Mammut rope has a small dot like that a few meters from the middle mark in each direction. The dots on my rope appear to be intentional. |

Your best bet is probably to start by contacting Edelweiss. Without anything to give a clue as to what it might be it will be pretty difficult to figure it out without damaging the rope. Otherwise, take it back to the retailer and they may exchange it for another one? |

Taste the purple part first as a baseline and then test the dark blue, probably just a sharpie mishap |
|
Josh, he said that there was a powder with it as well, so probably not sharpie. Maybe some sort of marking chalk? But again, I would not recommend tasting unknown chemicals. |
|
Definitely taste it - if you don't die, the rope is fine. |

i like to taste all my new ropes before i climb on them. i find that it gives me a special connection and trust with the rope that lets me climb harder. |

The rope is from backcountry.com so it is going to take a little longer than it would if it were from a local shop. I had been hoping to use the rope this weekend so I was seeing if I could get a quicker response here thinking maybe this is a common well known issue with new ropes and I wouldn't need to worry. But it sounds like I'll have to wait for a reply from Edelweiss. |

Powdery residue. Is it possible that this is colored chalk? Maybe they use dark colored chalk to mark things in the factory (e.g., where to cut), and some got on the rope accidentally. |

I actually tried washing it away with water and that was ineffective. I still do not know what it is, but Backcountry's customer service has been amazing. When I said I needed a rope this weekend, they rushed the returns process so I would have a non suspect rope this weekend. |

I would recommend contacting the manufacturer even if you end up returning the rope. I'm sure they would like to know this if it is, in fact, more than a cosmetic issue. If it's possible, try to hold on to the rope until you hear back from the manufacturer as they might want the rope back for testing. |

Start by contacting the manufacturer of the rope. They would know the most. |

While tasting chemicals to help identify them had been standard practice at one point (apparently our ChemE at work did this to pass a test because she didn't pay attention when they covered how to identify the chemicals through analysis), there are enough really bad chemicals out there you do need to be careful with it (we have cyanide compounds at work, I'm not tasting anything!). |
