653.0. "Buffing and cleaning" by PARSEC::PESENTI (JP) Tue Feb 24 1987 10:04

This month's consumer reports had a brief note that discussed CD compounds 
(for lack of a better term) that are used to buff out scratches.  They rated a 
few CD products against some other stuff.  Their results:  RALLY CAR WAX does 
the best job on restoring scratched CDs.  (Should this go in the car buffs 
note file?)

As far as cleaning is concerned, I've had good luck with water and a linen 
glass towel.  It's lintless, and leaves the disk clean.  I don't use any 
soaps, just a small splash of cold tap water.  Granted, I haven't had anything 
worse on the discs than fingerprints.  Anyone have any opinions on the 
mechanical cleaners available?

Also, what do you find is the best utensil for de-dusting the laser lens?  
I've tried q-tips, but end up with more cotton lint than the dust I was 
trying to remove.  (The unit is a portable Technics.)

653.1QUARK::LIONELFree advice is worth every centTue Feb 24 1987 11:043
    Everything I've read says to use either a soft brush or a jet of
    compressed air to clean off the laser lens.

653.2Wax sounds dumb to me....BETHE::LICEA_KANETue Feb 24 1987 13:039
    
    I'd be worried about not getting Rally Car Wax back off the disk.
    
    I've had very good luck with toothpaste.  Buff *very* lightly, radially
    from the center of the disc.

    Actually, Consumer Reports was testing a new product called Data
    Mud, designed for improving the readability of CD surfaces.  They
    (Consumer Reports) compared it with several other products, and
    found it to be about as effective as Rally car wax.  They also noted
    that Data Mud costs about $10/oz. and Rally costs about $0.40/oz.
    
    Re/ .2:
    
    	I would have thought toothpaste would be much too abrasive for
    	use on CDs.  Are you using one of the "Great tasting gel" types?

    I, too, have used regular toothpaste, along with a damp Q-tip, to
    remove surface defects (like air bubbles) from CDs (which were
    otherwise unplayable). Works like a charm, but should be buffed
    radially as mentioned in .2.

    re toothpaste: I have used Colgate (white and gel) and Crest with
    success.  I would hasten to add that you want to use very light
    pressure at first; increasing by small quantums; trying the CD between
    each pass of "buffing"; only use radial strokes.   All of my scratched
    CDs have been repaired in this manner; they seem to get scratched when
    I loan them out ;-)

653.6Buff gently, you should be fine....BETHE::LICEA_KANETue Feb 24 1987 15:1619
                
    I've used toothpaste for years to polish plexiglass for sculptures, and
    Erica's father has used it for a long long time for the same purpose. 
    
    
    I think that the last disc I polished I used "Crest Tartar Control Gel",
    so I don't think the disc has much danger of getting gingivitis.
    
    BTW - only polish a disc that is scratched so that it's difficult
    or impossible to play.  I take care of my discs, so they don't scratch.
    I've polished a few abused discs that I took out of the library.
    
    
    If you're really concerned, ask your dentist to recommend a very
    non-abrasive toothpaste.  If your dentist has a sense of humour,
    you might even mention why you are interested.

Which toothpaste would you recommend for a disk that has cavities?
653.8Flouride !NHL::NEILPeter C.Tue Feb 24 1987 19:388
 re .7

Tsk, tsk, use one with Flouride and your disk won't get cavities !

653.9Try this...CHOVAX::ERSEKRich ErsekMon Apr 06 1987 19:239
    Not that I've tried it, but when I used to work with plexiglas in
    shop class, we used something called jewler's rouge (a 1" dia. stick
    of red stuff) and a buffer to finish the sanded edges of the plastic.
    This worked very well, and if I knew where to get some (probably
    from a jewler) I might try it.  I don't recommend using an electric
    buffer though.
