Just figured I'd bring it up.
Lolon is hygroscopic when it comes to oils. The dark spot come from the lolon leaching oil out of the housings (the small amount that is left from production process.
The arguement for using 3 in 1 oils instead of silicone lubricant is that it will absord the oil and provide lubrication for about 30 days in average conditions.
Silicone will lose its lubrication after a shorter period of time. (debate will ensue I'm sure)
***Little known piece of trivia***
In suck through tests, lubricated cable took 70lbs of force to pull through a grommet of the three ring system while dry unlubricated took 90lbs.
Just useless trivia, not at all an excuse to not lubricate with silicone or oil.
Applications wood, plastic, metal and rubber surfaces. Use in moist and harsh enviornments. Not for use as an appeaence cleaner or on paint
Plastic Safe No

QuoteI have a can of CRC Heavy Duty Silicone Multi-Use Lubricant in a red can. Is it OK to use to lubricate my yellow (Lolon-F) cutaway cables?
Can says it contains Acetone, Heptane, Dimethylpolysiloxane & Hydrocarbon propellant.
I did a search and saw some posts about avoiding the Ace Hardware red can due to residue, then someone replied saying CRC had lots of products but avoid the red can, but with no explanation leaving me wondering it that was confusion with the Ace product or if ACE just rebrands it.
I did some test sprays and I think the acetone screws up a lot of plastic surfaces people have used for testing. It seems that there's no residue except the lubricant after the propellant evaporates on the right surface.
Here is the exact product:

It seems sound enough, before I take the plunge, has anyone used this on cables? Will Acetone react with Lolon-F?
Thanks.
food grade silicone is what I remember reading somewhere is recommended. I finally found a place to buy - an industrial supply outfit.

Do they have an Ace Hardware in Ontario?

Rarely.
A decade or so ago, Parachutes de France issued a Service Bulletin telling riggers to clean cutaway housings that had a excess of cutting oil remaining from the winding process.

Aerodyne put out a SB on the same thing in March 2005.

QuoteI just got back from Ace hardware. I wanted to try out the CRC food grade but they only had the heavy duty. There was plenty of Ace Pure Silicone Lubricant available.

we don't have Ace Hardwares up here. I have checked all the ususal consumer outlets without luck. I bought a bunch of cans of Osborn Food Grade Silicone (product number 76194) at Acklands Grainger (an industrial supply place) just 5 minutes from my work. I gave to a couple of cans to dropzones because no one I know bothers to lub their yellow cable. I have a Racer with the red cable so never need to lub.

Here is where you can get the stuff...rm

For example, many years ago - when I was working in the loft at Perris Valley, California - I guy brought a grimy rig in for repack, so I attached a fish scale to the cutaway handle and was surprised by a 25 pound pull!
After cleaning the cables, the pull force dropped to less than 5 pounds.
Note: TSO C23D says that release systems (i.e. 3-Ring) can have a maximum pull force of 22 pounds (10 kilograms) the same as ripcords.

what really matters is the force to release under a small spinning elliptical in line twists. I would like to see those test results of the "3 bloke test" where 2 extra guys are hanging from a hanging harness in lines twists. If I had the yellow cable, I'd be lubricating it regularly and I'd use the recommended food grade silicone....

What is the maximum pull force on a chest mount reserve?

QuoteSmart ass.
That would be me. 15 pounds is the maximum allowable pull force, but it's easy to create a much higher pull force by bending the pins.

I am not sure I know that method of packing, is it somelthing new?

QuoteI'm not a chemist and have not recently, slept at a Holiday Inn Express. I do have a question. Isn't acetone used in some paint removers and wood re-finishing compounds?
I'd known it best as nail polish remover. It's a powerful solvent for lots of stuff.

I might test it some day if I can get some spare cable, but for cleaning my cables I'm taking the advice here and on other threads.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Cutaway cables should be lubricated the same way as machine guns - in the desert.
Use some sort of light oil (i.e. WD40) to loosen the dirt, then wipe them almost dry.
Dry, clean Lolon has excellent self-lubricating properties. Lolon only sticks when it has too much grim, sand, salt, ferrous oxide, gunk, etc. on it, ergo, the less lubricant you leave on cutaway cables the better.
Good to know thanks.
