B-Man 4,768 Posted April 23, 2015 Posted April 23, 2015 Just thought I'd share something I tried on a whim. I have been ripping my entire CD collection again into FLAC files and noticed that the PC was having a hard time with Jackson Brown - Running On Empty. I ejected it and discovered that it had a pretty long scratch running diagonally from the center hole almost to the outer edge. I figured that there was nothing to lose, so I grabbed a microfiber cloth and some of this from the garage : I use it to take hazing and small scratches out of vehicle paint so how bad can it be, right ?? Not to go too hard against the common consensus (which is to not rub a CD in a circular motion) I put a little of the glaze on the rag and rubbed it in a circular motion until I could no longer see the scratch. Actually, it was still faintly visible from an angle but I figured it would be better than it was. I wiped all of the residue off and it looked 100% better. I threw it back into the drive and JRiver ripped it with no errors or retries. I'm sure if the scratch is deep enough it wouldn't help because it is not a very aggressive polish, but for the light stuff and stubborn smudges it sure does the trick. Smells like bananas to boot !!! 7
danowood 2,167 Posted April 23, 2015 Posted April 23, 2015 Good show Brian. I wonder about the differences between the lasers used on units now in comparisons to the ones when they first came out. I remember a demo done when cd's first came out. A cd was taken and a fine sand paper was run across it to put scratches in it and then played in the cd player and it played flawlessly. Even cd's that had pretty deep scratches in them played without fail. Nowadays, it doesn't take much at all for it to skip, etc. I wonder if the lasers are cheaply made and less stronger than in the good ole days? Opinions?
kve777 6,782 Posted April 23, 2015 Posted April 23, 2015 I like using a butane torch. One of those pencil things. Gotta be quick, but it really works! Uh, then there's THIS 1
danowood 2,167 Posted April 23, 2015 Posted April 23, 2015 "less stronger" as in not as strong a signal beam or Whatever the reason, the units today and for some time are more sensitive to cd's than on the onset IMO. I don't speak Anunnaki so I can't translate
zumbini 6,146 Posted April 24, 2015 Posted April 24, 2015 A CD consists of a thin aluminum or gold data layer sandwiched between 2 polycarbonate discs. Data is written as a series of pits and lands (1's and 0's) in a spiral track beginning at the center with the TOC. If the data track were laid out linearly it would be more than 3 miles long. If a CD refuses to "boot up" it's likely the lead-in track containing the table of contents has been damaged. Polishing/refilling/reflowing the polycarbonate can be effective if the data layer has not been comprimised. Pits are closer to the label side of a disc, so CDs are more likely to suffer damage on the label side of the disc. 2

So I bent down 'n I reached down 'n I scooped down An' I gathered up a generous mitten full of the deadly...

Here it goes, RUB IT! (HEY... HEY... HEY...)
4krow 5,863 Posted April 24, 2015 Posted April 24, 2015 I tried using a special CD polish once and as careful as I was, I ended up making very light scratches in the disc. The original idea from the seller was to make perfectly flat, the surface that the laser had to read. Looking back it sounds like just another sales product. In the case of an already damaged CD, the polishing idea is More Better. Ummm, just trying to fit in guys.

LVMAN777 322 Posted April 24, 2015 Posted April 24, 2015 I bought Novis for polishing the dust cover/lid on my Technics DD Linear TT 1
4krow 5,863 Posted April 24, 2015 Posted April 24, 2015 Lyman, I am supposing that it worked on the TT cover. The question that I might have is about the many different plastics and how they would respond to a polish.

Removing deep scratches takes a lot of effort though so I recommend using a low or variable speed orbital buffer. 1

Sagamore2007 71 Posted April 25, 2015 Posted April 25, 2015 Thanks Lyman for the link to the Novus product. I have been looking for a product to try to clean up a Pioneer TT dust cover. I'm also curious to see how it may work on some window panels on my Wife's Jeep.

Friction heat does nasty things to a TT cover. How do I know you ask? I just do. 2
Nahash5150 10,305 Posted April 25, 2015 Posted April 25, 2015 I use a buffing wheel on my bench grinder. It works great! I've revived many CDs and DVDs from toddler treatment. Just gotta be gentle and buff inside to outside...
dennismiller55 4,738 Posted April 25, 2015 Posted April 25, 2015 I use this: JFJ Easy Pro DVD/CD Cleaner. I have had it for at least 3 years. Does a beautiful job. I bought over a 1000 CD's on Craig's list that did not come in cases. They were in bad shape. Some were saved by this machine if all the damage was on the non print side. If the damage is on the print side there is no hope.
