Will penetrating oil damage a rope?

I was wondering if someone were to use penetrating oil to remove a bolt on a route, and then touch their rope with the oil on their hands, if the rope's integrity would become compromised from the solvent.

Specificaly this oil: http://www.gunk.com/item_details.asp

MSDS: http://www.gunk.com/msds/L104.PDF

Oil contents:

2-Butoxyethanol 3.0 - 7.0%
Naphthenic Petroleum Distillate 7.0 - 13.0%
Natural Methyl Ester 40.0 - 60.0%
Refined Soybean Oil 15.0 - 40.0%


The stuff is listed as being potentially lethal if swallowed and flammable, however is not listed as corrosive. There is nothing in the MSDS that indicated its acid like in any way.

You could try testing the ph of the oil to see how acidic it is.

try mayonnaise or peanut butter. if that doesn't work, try it again, but with a screwdriver this time.

Just figured I'd add to all the other useless ideas that have been offered and will be offered. Call the manufacturer.

Unfortunately somebody I was climbing with got grease on my rope. Grease is a petroleum based product and alone should not cause any damage. BUT, grease can contain additives (Also, depending on the medium its stored in it can possibly contain other contaminants) in some industrial applications and in my case there was no way to tell what components were in the grease (this could parallel oil composition????).
I emailed the manufacturer and they suggested I retire the rope (no surprise there).
I did use the rope on two occasions after the exposure for TR setups. Considering the importance of a functioning rope to efficiently distribute energy when falling, I will not use it while leading.
Washing the rope with Bluewater rope cleaner removed the grease, but long story short-Iím going to buy a new rope because I think the 180$ is worth eliminating any anxiety while climbing.

climbing rope is made out of petroleum products, you can soak it in gasoline or other like products and it won't do anything. but to be on the safe side contact the manufacturer

styrofoam and gasoline are both petroleum products. Youtube has some neat videos of kids mixing them together to form a gooey mess

I'm not aware of anything on that list that is known to damage Nylon. I am just a bit curious about the "natural methyl esters", but the chance that that is homemade Biodiesel with a signif. amount of residual sodium methoxide is pretty far-fetched. And that's the only remote possibility I can come up with to worry.

And the amount of this oil that may have contacted the rope sounds absolutely miniscule.

Naturally the rope manuf. will recommend replacement; what else could they say? The oil manuf. probably don't even know what climbing rope is. So their input is useless IMO. YMMV.

I used to do that all of the time. I am lucky I didn't burn my house down.

Maybe methyl ester is similar to denatured alcohol? Just a guess.
Petrolium isn't an issue in the form of gas or oil, but that's not to say that additives aren't. Cut a little bit off the end of your rope and soak it in that stuff overnight. See what happens. If you use a longer section, say 15-20 feet. You could probably take it to a crane and rigging shop to have them test it on their puller if there's one in your area. Or just try and figure out exactly what the additives are.
I would also hazard a guess that if you just had a little on your hands and ran it over your rope, like during a rappell, it wouldn't be much of an issue, but it's your piece of mind, which is worth the cost of a rope.

Soy oil is commonly used in "green" strippers for paint and gunk. I wouldn't sweat a little residue off a bolt. The other ingredients would most likely have evaporated before they can cause damage.

The rope cleaner would probably take care of the problem but why take a chance. I have a tensile machine and would test the rope and post results if you want to send in a piece versus a clean section.

Send an extra section that I can soak in gasoline! Seriously people?
