Hi

Looks like this is the best forum for this tip. Excuse me if it's not.

My original xp cd was scratched so bad I couldn't copy it to make my unattend cd. The only backup I had was slipstream with sp1a. I tried a few programs to recover all the files from the original disk, but none were 100% effective. Then I read about toothpaste. Unfortunately I can't remember the site I read about this on.

Anyway, get some cotton balls and put some toothpaste on them. Rub your scratched cd with the cotton balls until the majority of the scratches are gone.
Rinse the disc with water and dry it with a cloth that won't scratch.

This worked great for me. I just used paper towels to rub the toothpaste in, and to dry it. I put the disc in and was able to copy and paste the disc onto my hard drive without any errors.

The stupid $20 cd cleaning device I have couldn't even get all the scratches out.

I didn't wipe the disk until all the scratches were gone, just enough that a large majority of them were gone.

If anyone is interested, I used Crest Multi-Care mint flavored toothpaste. I only tried this since the disc was so damaged I didn't care if I completely wrecked it.

Hope this helps some people out.
Bleach gets you young, so I've been told. Cause no one who drinks it lives to get old.

Yep, some toothpastes are good, not all of them though.
Best product is BRASSO or similar polishing pastes, read here:

That's a good tip. I had heard of it before, but never tried it out. I would be wary of the following...

Rinse the disc with water and dry it with a cloth that won't scratch.

If there is any way for water to get under the surface of the label, you can kiss that CD gone within about 2-3 months. The water will evaporate under the label (that also contains the data layer) and create a hole when it evapourates. This hole will then expand as you use the disc, taking the data layer with it.

@zxian
thanks for the info. I made sure to make a fresh burn after I retrieved the data. It's my understanding that rubbing alcohol is good to clean disks, correct me if I'm wrong though.


I don't floss.......I save the food in my teeth for a snack. :thumbup

I always just use a soft, clean cloth (even a clean t-shirt will do) and my breath to clean CDs. No need for any fancy chemicals or cleaners.

Breathe on the CD a bit (so you get the condensation on there) and then gently wipe radially (i.e. from the center to the edge) making your way around. DO NOT WIPE IN A CIRCLE OR AROUND THE DISC!!! Keep that habit up and you will end up with a scratched disc that will be very difficult to repair.

Although you should be handling your discs either at the center or the edge anyways... so cleaning shouldn't be necessary... ;)

There is also a "last resort" technique, really only useful to salvage data from a badly scratched CD, that will be thrown away afterwards.

The real problem with scratches is the "sides" of them that "confuse" the reader, by polishng as detailed above, you flatten the scratch, but sometimes the scratch is so deep that it is impossible to do that, so there is this other way, FILL the scratch with a transparent material.

Two candidates:
1) Car WAX
2) Car glass (windshield) silicon/teflon based spray coating

Of course you need to WAIT until the product has completely dried off, BEFORE polishing the CD with a cloth and insering it in the drive.

I suppose the gel is equally effective (since I use the gel). :hello:

Now we can argue whether breath or alcohol will break down the cd faster B) since saliva is intended to help break down food would it be worse than alcohol on a cd?

(I'm being just a bit anal retentive now lol)

COOL.....Toothpaste gets an MSFN Forum 5 star rating!!! (maybe it shoutd be sticky......(really bad joke))

I never said I spit on my CDs... It's mostly just water vapour that then condenses on the CD. :P

I know you menat you were not spitting on them. the vapor that comes out of people's mouths is not water. Even if it s water, would the minerals that are found in water. Depending on where a person lives determines how much and what type of minerals are in the water. Even with a water filter there are still some minerals.

Alcohol on the other hand does not have any minerals, so it is not as abrasive as water (of course I am referring to 99% alcohol). The problem with alcohol is that it's chemcal quality takes off some the coating on the disk.

:D (one of these days I'll figure out how to quote correctly)

If you drink three or four glasses of Absolute vodka BEFORE trying polishing a CD the whatever is in your mouth will be VERY like Alcohol, .....but you would probably lose interest in the actual CD polishing....

I would not recomend using gel toothpaste! The abbrasive in it is much coarser than in regular toothpaste.

Breathing on a disc deposits halitosis and water (in a small quantity). The amount of water shouldn't do any damage but the halitosis could peel the information layer off. Check first by breathing on wallpaper. If it peels, then use the toothpaste, gel or regular, on your teeth. Then breath on the disk.

All kidding aside I find that car polish will get the job done so you can make a copy.
