Step 1: Scratched DVD

A badly scratched cd or dvd that wont work anymore.

Step 2: Machine buffer

I found a buffer cheap,this can be bought at your local hardware store . The buffer can be fitted to a normal drilling machine.The buffer i bought came with rubbing compounds-1.course-2.medium and 3.fine. Fit this into your drilling machine.Start with the medium grade rubbing compound.Then use the fine compound.

Step 3: Buffing the disk

With the machine running add compound onto the buffer, a small quantity should be sufficient.Move the disk in a circular motion, with gentle pressure onto the buffer.This shouldn't take more than 3-4 minutes.

Step 4: Fine buffing

Once all scratches are buffed,add some fine compound to buffer.repeat same as step 3. the end result should be as the disk was new.

Step 5: All scratches gone, good as new

TOP TIP NO 2 if your Cd's are skipping put them in the deep freeze over night and try them in the morning! don't ask me how or why but believe me it works every time. ps/good instructable by the way:)

Hey Chalky,
THANKYOU! you just saved me several hundred dollars, my Office cd wouldn't install after an OS rebuild. I KNEW there had to be an easy way!
You are my new HERO!! xx
p.s. to my last message:
you have to follow the scratch remover instruction to the T or it WILL NOT work.
one thing that i have found that works is use a green scrubber pad (found in most stores) and some scratch remover (found anywhere that cds/dvds are sold (typically)). sand surface with scrubber pad until the main scratch is gone (do not rub hard) then use your scratch remover and follow instructions. repeat if necessary.

I have the better idea than you have.
First, layer the CD with toothpaste. Then layer it with peanut butter. WIPE IT with tissue or soft cloth,you can use kitchen towel. Repeat the same process. Then dip it in the mixture of coke and soda for about 30 minutes. don't forget to shake. Then, Amazingly all the scratches of all types will be removed. This method works perfectly. For test, I had used a manually scrached CD scrached severly by rubbing it on cement surface. The result was far better than this messy valseline job.
Is this Amazing I have GTA 3 for PC its scratched for sure thanks gr8 idea what about gashes??? let me know*

i want to know that data on the cd got viped out or still on cd?..?...?

or u made total new cd?.......?......?
please answer..................... 
The data isn't stored on the plastic at all, but rather the metal foil behind it. the reason scratches ruin the disks, is they interrupt the laser beam as it crosses that part of the data; if you smooth them back out (refinish/resurface/polish the disk) it becomes readable again.
now i can reuse the cd which i was thinking to through out
thanks for your reply .............................
thanks thanks thanks thanks ......................................................................................

The best polishing compound that I have found for this method is "Disco" brand, for plastic. you can find it at most Ace Hardware stores. I've been using this way of saving discs for over 2 years now and it's the best that I have found. Works on all types. If it's plastic it can be polished, as long as the metal foil has not been damaged, or the disc cracked. Just be careful not to press to hard or you can over heat and melt the plastic.
Good Luck

Hmm, the last time I used a buffer I burnt the plastic. How do I prevent that?
Broom wertokz5 years ago
Work with a lighter pressure, and don't stay on the same area for long. Or, you can work with the CD barely submerged in water, or under a running stream.

what about a dremel at a low speed? I have a buffer and compound, but I'm afraid I might break the disc.
the dremel doesn't cover as much space as a buffer does. a low speed will do nothing but burn the disk
I would try it on an un-important disk first
Don't hold it in your hand, but it on a flat surface so it can't bend. It should work fine

I make iso's out of the cds and put them away in a 100 disk blank spindle.

I usually buy cases for my disks and make sure they are not scratched. The last thing I want is to not have the driver disk for say, a motherboard working... Just keep em safe and/or go to the computer store and buy a 100 pack of those paper sleeves with a clear front.

This is great, i have a few scratched disks (mainly from little brother and dog)] Unfortunately i don't have a buffer, but my DT teacher at school has one so i can use that after the summer holidays :P
