Cos 11 Sticky cable- not from tape...

Recommended Posts

I was pulling out some older cos 11 lavs that I haven't used for a while, and one of the mics' cable sheath has started to degrade. It looks normal, but the entire length of it has gone sticky.  I'm going to try a few terrifying solvents I have lying around (start with citrus, then alcohol, then naphtha, then xylene, then acetone, then Methyl Ethyl Ketone)   but wondering if anyone has come up against this and can recommend a fix?    The mic works fine apart from the fact that I can throw it at the ceiling like a piece of spaghetti and it will stick...  The one interesting thing about this mic is that it was bought second hand with a transmitter, and it's sheath always seemed a bit different than all my other Cos 11's, I not sure whether Sanken changed how they manufacture the cable at some point, or whether it got contaminated with something at some point in its lifespan.

Any thoughts?

 

Cheers,

I started down the list (and added a few)

99% alcohol - no change

Dish soap- no change

Fast orange citrus with pumice-  a little bit cleaner- maybe the pumice rubbed some stickiness off.

Naptha (Coleman Fuel)- no change

brake cleaner - no change

Acetone- no change

Xylene-  This actually seemed to clean the stickiness off.  It left the rubber sheath a bit soft though, so I rubbed on some 303 Aerospace protectant, which seemed to reconstitute the rubber a bit, and made it feel normal again- though now I'm noticing that 3M Transpore tape doesn't like to stick to the 303.

Not sure about your specific problem but I've used WD-40 to make mine like brand new.  Takes a few applications and a bit of elbow grease.

Not to mention that wonderful smell it leaves behind.

I have a similar issue with the cable of a sanken cos 11d that got sprayed with diesel fuel during a reality shoot. I cleaned it initially with warm water and some washing up liquid and with tea tree oil later on. This helped a little but it still tends to develop a residue in the plastic case. It's my "sacrificial mic" now and gets used in any dodgy setups.

I use surgical tape residue remover for Transpore goo, where the 'usual' solvents do not work very well on that. Unfortunately it's not available in the usual suspect US pharmaceutical stores (CVS, RiteAid, Walgreens, ect).

Yup, 

 

That's what Remove is. It is available in Drug stores that have a home care section.

Amazon.com in the US lists it - Try Remove Universal Adhesive Remover Wipes.

 

I just get its at a Lawton's Drug store with a homeware section here in Halifax, NS

Not Homeware, but home care. oops

So I looked up what's in Remove Universal Adhesive Remover and it's mainly dipropylene glycol methyl ether. And Naptha.

I wondered what I had around the house with those components and realized that automotive starting fluid was kinda similar.

 

And it actually worked pretty well to clean a Sanken RM11 rubber lav mount that was massively gooed with 3m Transpore tape adhesive.

 

Spray with starting fluid.  Scrub with cloth or paper towel, and rinse with 99% alcohol.

 

So until I track down some Remove, this will serve to keep the rig clean... with something that's easy to source and usually in my garage anyway...

 

Haven't tested it on an actual lav cable yet, I'll try that tomorrow.

Found some Remove wipes at a local medical supply store. (Lancaster on West Broadway if you're in Vancouver, BC)

 

Rather expensive at $25 for 50, but I cleaned 6 lavs and mounts with 2 wipes, so that's probably good for years...

 

They worked really well!  Thanks to those who found and recommended them.

It's good to do a final wipe with alcohol since the wipes have aloe vera in them which leaves the wires and mounts a bit "moisturized"

 

And if you're really cheap, automotive starting fluid is $5 for a can that will last forever, as well as get your horrible old lawnmower running in the spring.
