Scratch removal before ripping


Has anyone bought one of those tools that you load the CD into and it supposedly removes the scratches from the CD? I found a great store with used CD's that sells the CD's so cheap it's crazy...and they seem to have everything. I've been luck so far that none have been scratched but I'm sure it will happen soon.

So, if anyone has used this does it degrade the sound quality before ripping? I wouldn't think so but figured I would ask first.

Thanks

Toothpaste is the perfect mild abrasive! I have been using it with good results for over 10 years- I apply it with my finger.

The reason an abrasive is neccessary is that the scratches create imperfections in the finishing coat of the disk. When the laser hits these imperfections it's beam gets reflected causing the pickup to error out.

Once the imperfections are smoothed out the laser has a clear shot at the data underneath the finishing coat. Not all scratches can be worked out but many can.

Do you think that the Disc Doctor does NOT change the sonics? I just want to be sure that using something like this will NOT change the sound of the CD. Yes, of course there will not be a skip! :)
This is what I've been looking at: http://www.digitalinnovations.com/disc_repair.php
Although I keep all of my CD's in pristine condition I use optrix spray on most of the DVD's that I get from Netflix. Many of them arrived so scratched up as to be unplayable. Optrix has salvaged almost all of them!
Huh, toothpaste. I'm sure it works well But Is there a sonic difference between Colgate and Crest? I'll have to do some AB-ing and let ya'll know my findings. One thing for sure, my disc will have fresh breath and no cavities! Sorry I just could help myself! LOL!
