In Reply to: Cleaning Old R2R Tape posted by Vinyliac on June 19, 2004 at 18:03:10:
I hope I don't offend any wayward invironmentalists on their way to a meeting of the Sierra Club....Mount your reel tape on a movie film cranking rewinder.
Common brands are Craig, Kodak, Keystone... etc...
These are manually operated cranks that will wind film (or audio tape) back and forth between full and empty reels like this...O~~~~O
Grab the tape between thumb and index finger with a clean lintless cloth that is damp with carbon tetrachloride. Then crank the tape slowly, thereby cleaning the tape.
Points to remember are:
Keep advancing the cloth to a clean spot as it becomes discolored.
Crank slowly to allow the Carbon Tet a chance to evaporate BEFORE it winds up on the opposite reel.
Probably best to do this in a highly ventilated location and wear gloves.Please observe all other safety precautions that one normally learns in life.

p.s. oh yea...don't forget to rewind the tape back to it's feel reel with tails OUT. *hehe*
Follow Ups:
thanks for the thoughts and instructions; where does one find this chemical?Cheers!
... are somewhat less hazardous cleaning solvents related or similar to carbon tetrachloride.Carbon tetrachloride is very hard to get even in the industry, and even we're even discouraged from using the solvents I mentioned above nowadays. You should read the MSDS's for these materials if you use them and aren't familiar with them already.
In the good ol' days, carbon tet was used in fire extinguishers. My father used to fill a 50 cc (glass) syringe with carbon tet and kill wasps "on the wing" :-)
Yes....Those are better chemicals.
Thanks for putting that forth.....
Do you live near a major metropolitan area ?If you do..consult the yellow pages under scientific supply.
I bought a quart of the stuff about 20 years ago, before it was a semi-controlled substance.
Whether you'll be able to obtain any without some fanaggling, winking, or arm-twisting is a toss up.
IF your local chemical house (Nurnburg, VanWater & Rogers..etc) refuses to recognize you as a responsible non-terrorist person with good intentions and won't sell it to you...just put on a smiley face and ask them politely to 'recommend' a safer substitute.
I know there are a couple chemicals that ARE safer, and thereby less controlled...but they may not be as effective.
I already have carbon Tet, so I haven't made any efforts to discover a substitute....but I suppose if PUSH came to SHOVE, and after exhausting all alternatives, you could experiment with alcohol or naptha.
As with all unknow applications, you'd be wise to start on a trial basis - experimenting with the smallest quantity possible on the smallest surface area that will allow you to evaluate whether it's doing the job.
Start with small amounts and if it's NOT working, gradually increase the amounts until you get results.....all the time keeping a weather-eye out for signs of trouble.
Naptha (lighter fluid) is the most refined product on the petroleum list. It evaporates rapidly, is not particularly caustic, and leaves little residue. I recommend it for many cleaning jobs, but I can't predict just how it might react with organic contaminants such as mildue, mold, lichens or mushrooms!
*heh*
Good luck.
