Cleaning Filthy CDs

A pile of used and poorly stored CDs has come my way that would be hard to replace.... they are filmy, blotchy, yukky..... but not, it seems, dinged or actually scratched. What is safe to use to soak/wipe off the goo?

Step one is to let them come to room temperature without messing with them, for the condensation issues.... one CD, my player rejected as unreadable. One I am ripping and playing as I type, so I know there is stuff here to harvest.

Talk to me!

pass them over to a priest or minister given your background of postings they may be wiccan/cult infested

Very funny!

You must have the second sight to see what I've got sitting in front of me-- but my priest husband gave them into my care! :~)

OK - Wysy

No lie, the straight-dope..no fooling...this is the straight dope.

1. Soak a soft (old, soft, 100% COTTEN t-shirt/diaper/sock) with PREMIUM (no sugars added) VODKA (grey goose etc) ....(unfortuately Rubbing/Isopropal gives a haze)

2. Gently rub the disk and wipe with soft cotten dry cloth.

GUNK - should be removed-
If GUNK came from adhesive stickers - wipe with olive-oil.
Repeat - Vodka treatment

3. If scratches remaine - rub entire disk surface, in a gentle circular direction for a couple of minutes, with a regular, over-the-counter, toothpaste.

4. Clean again with vodka.

5. Set aside for a day

ENJOY!!

Sincerely,
Gargoyle

Soap and water may do it, but be careful to rub/clean from the inside out or vice versa and NOT in the direction of play/circumferentially. These are proprietary cleaning machines that sell for around $ 20, and use some sort of special cleaner, perhaps alcohol and water with a bit of a surfacant to break down surface tension..

OK, but I'm gonna drink the used vodka and then I don't care what they say about vodka, it does too smell-- so I'll brush my teeth with the leftover toothpaste, too.

Thank you for sharing your straight dope. :~)

I rub them with straight dishwashing liquid, and then rinse them off and wipe with a cotton cloth.

WYSY - Please - Do NOT drink the USED vodka.

This stuff was gunk...you probably have cleaned off mild, molds, fungus, or even worse. It might give a glorious, momentary, "high" but the results could be deadly. Don't drink the USED vodka.

For what remains in the Grey-Goose bottle.... save it for guests.

Sincerely,
Gargoyle

You may as well of confessed to drinking from pub urinals....Don't drink.

hold each disc safely over a boiling kettle..

let the warm steam cover the disc surface for as long as you feel comfortable,
then wipe with a clean soft lint free cloth, or tissue,
from centre of disc outwards as you revolve disc in your hand..
do this as many times as required until each disc is free of grease and sticky residue..

..another wipe over with a similar dry clean cloth..
and disc will soon enough be ready for playing

..this method works very well with crap covered DVDs from local hire shop

The alcohol "cure" also works with vinyl records.

DO NOT use with LACQUOR rolls.

DAWN - is sort of the "universal Hard-Core to the roots" cleaner for cloth, and glass.

When the brother's kids were small, he asked me to fix his CD player. I looked at the CDs first- they were all covered in little jammy fingerprints. A quick wash (I used warm water, detergent and cotton wool) and all played perfectly. He hailed me as a genius on a plane with Brunel and Einstein, and not wishing to disappoint him I never told him about the method used.

for heaven's sake, don't put filthy discs in a drive or player, even for a 'test'. You could render the player or drive dysfunctional. It's not worth it.

Have had good luck with just gently washing them like you would a dish with clean soapy water, rinse with plenty of clear warm rinse water, blot dry on a lint-free towel, let air dry the rest of the way before putting in a drive. But I'm not an authority, I think you might want to wait for a true expert to put in 2 cents on this.

Warm water and standard washing-up detergent always works for me. Use a decent soft cloth to dry them though.



I had to do 30 CDs like that rcently. A ceilidh band, who should be shot for crimes against musicianship, decided a month wasn't long enough for them to sort out some sets of tunes as asked, and tried their best to wreck the CDs we were forced to use instead. Some scratched, all filthy, and their CD player in such a bad state there was a loud burst of feedback every time a new CD span up.

Aumeter musicians, but professional self-publicists. We burnt them in effagy on the 5th...

To clean up a Chubby Brown CD you would have to shred it into little pieces. Then wash your hands afterwards. :-)

I cannot believe that the person who suggested vodka was being serious. Surely it doesn't make sense to use any kind of solvent on plastic.

Wysi, I suggest you spray the CD's with water from a spray bottle. Let them sit a while, then rinse them in lukewarm water. If that doesn't do it, try tepid water and gentle soap.

Risk from solvents is not of dissolving but of cracking the plastic where the solvent interacts with stressed zones in the moulding. Haze is very fine microcracks. If you have to remove something that won't shift with soapy water white spirit should be ok, but I wouldn't risk alcohols

Does this treatment shorten the life of a CD? How long do CDs last anyway?

This has been really interesting. The CDs had gone camping, you see, several times, and were a gritty mess when they were stored in a cold place for years that had lots of condensation.

Thing One that I learned was that professionally burned CDs are a lot tougher than home-burnt, just as people have been saying around here for a long time. Some of them got wiped pretty hard in a couple of places, but play/rip fine.

Thing Two is that some CDs rip in about half the time others do-- which must mean that they don't have very good sound quality to start with-- bit rates or whatever?

I soaked them in batches in very soapy warm water, rubbed off soap film with care from the center out with soapy fingertips to feel for the stuck stuff, and in some cases used cotton rag scraps to get real stuck bits moving. Then rinsed REAL well and set at an angle to dry, followed by gentle wiping to remove water stains and check for cleanness/mirror finish. A few flunked and got resoaked or done over with straight dish soap.

All but a very, very few are playing just fine. The failures had gouges before I started, and the rest have all stood up to my ministrations.

I think I did about 50. Worth doing!

Translation Please What Is "white spirit should be ok" WHITE SPIRIT????

Plastics, generally, do not disolve in alcohol, (shellac, made from insect bodies does, and the fine furniture finish of alcohol, linseed oil, and shellac is known as a "French Finish" and used on antique furniture.

Plastics are advers to the petroleum family (also a carbon compound) however, plastic death is knealed with substances such as paint-thinner, acetone, tholemyne, and gasoline.

On the side of water ( one of the grandest of all solvents)combined with DishWashingSoap...it probably should be anyone's first choice. (The antique, silk, Chinese, rug...came out beautiful for $1.25 and four days of drying....unfortunately, the rats had eaten holes where the cat-crap had sat.)

Garg is really correct - never use any solvent but pure, (preferably distilled) water on CD/DVDs - you MAY add a little ethanol if the marks are greasy (fingerprints).

I say pure water, because any dissolved salts will deposit as the water evaporates.

That's a good thought about the pure water and the dissolved salts, Foolstroupe. I hadn't thought of that. In the U.S. we call it distilled water. To save money, it could be saved for the final rinse.

White spirit is a paint-thinner.
