Hi,
Try the Philips cd spray as its very effective,use the Anti-static cd cleaning cloth ( not a cloth but some sort of velvet with different material). I used these and seems ok to me !

Hey that sounds like a good idea. I sometimes use the antistatic cloth bit that I got with my cellphone these days.
But to be frank, unfortunately in my case, involuntarily I start with wiping the CDs on my t-shirt (yeah.. I know, I know
) before sliding them in to the tray! It worked beautifully for all these years
mekr, were you mentioning about the fungus kinda stuff on old cds, the type that doesnt come off no matter what you do - but strangely they seem to playback with out any obvious problems!
Cheers.

I just soak them in a mild detergent mix for about 2 minutes. Take them out, rinse well and put on a newspaper to dry by itself.
Proper handling throughout.

Adventure CD cleaning
I have been wiping my DVD & Cd's with the special cloth which i got with the dnp fibre screen.
I would not have the guts to wipe the CD on t-shirt or soak them in detergent, it is only you good people can do this, because you'll know too much about the av accessories and equipments, by the way after eating food, very often i wipe my hands in my trouser pockets.

Hi,
Can clean with any MICROFIBRE cloth as there are no chances of scratches.
Scotch Brite is now making these small microfibre dusters and retailing all over.I bought one from Rhythm House for Rs 70.
For those stubborn stains/marks that dont come off try the phillips cleaner as mentioned above. I have a bottle of CleanSpin which is similar and works well too.
Actually in mumbai i have a problem with excessive moisture on the cds(live close to the sea) and hence this cleaning cloth is very handy.
Regards

Hi,
You are not alone Unleash I do it all the time aswell (though use vests (baniyan) cloth) but I've seen sometimes it makes few scratches.
Nowadays I've found the best Idea ! I copy all my original discs and use them only keeping my valuable originals in the locker ! hence even if the cds conks burn another one and use (cost of a blank cd is hardly anyhting to worry too much) !
Anyway coming to the topic, one can use Iso-propel alcohol which is available in any electronics spare parts shop (but be careful to make sure that is a genuine stuff). It works perfectly with any type of dust ! another alternative to mask the scratches is,take a very very small quantity (make sure not to use much) of cocoanut oil and gently polish the disc using some cloth (as mentioned baniyan cloth is the best) it works like a charm. give it a try and see guys !!

My Onkyo DVD player started giving message No disk every time i inserted a dvd even new purchased, I thought perhaps the dvds had some problem ven made my mind to return one of them. Then I noticed the dvds which were earlier palying fine also player gave message No Disc. I used all sort of dry lens cleaners from Philips to others, but of no help. I opened my dvd player, pulled lens to comfortable position from the hood where i can directly see it from top, cleaned with little wet bud replaced cover and every dvd now works fine.

Hi,
Sulabh good to hear that it worked !! the use of lens cleaners is only limited to certain level ! I mean if you have not used them since you bought the equipment say 1 or 2 years then all of a sudden you buy and use it,this won't help ! you have use it regularly to get proper results !!
Also when trying to clean the optical sensor (lens) use extreme caution otherwise it could lead to damage of it ! if even some amount of moisture is gone inside the sensor unit and touches the semiconductor laser then kiss your lens goodbye!! also they are very sensitive to static !! so you have to be in some kind of anti-static condition when you have to touch such sensitive devices !!
Believe me I have lost hell lot of lens by trying to do similar cleaning !!

1. First of all, its good practice to handle CDs with care & consideration.
Keep them in the case right after use, handle them with the centre spindle hole/outer edges.
2.Use a soft cloth( no T shirts/banians ! ) e.g the velvet cloth they hand out with spectacles to wipe dust off the CD, wiping radially from the centre to the edges; DO NOT wipe in a circular, concentric direction.
3. If still reqd, next wipe radially again, with the soft cloth slighly dampened with water.
I have been following this method & have had no problems.
4. In case of scratches which interfere with playback, use a soft cloth dipped in Brasso/Silvo & polish the CD, again in a radial direction. This really does work in removing scratches & restores the CD ! This will however not help in case the scratches are deep & have penetrated to the dye layer/reflective layer.

......I copy all my original discs and use them only keeping my valuable originals in the locker
...and I thought I was weired!
Glad to know there are skeptics like me out there
!!! - I do exactly the same, along with parallel back-ups on harddrives as well in wave. I even prioritize my choice, the originals CDs are exclusive to my beloved Marantz Reference gear (yeah, yeah I used the R word, bite me!), the backup cds goes to the other systems!Hi all,
Sulabh please dont do that again. Ur player may never read a disc again as the lens is delicate.
Soundsgreat banyan may not be a good idea as it has some percentage of lycra so when u swipe the cd am sure there is some kind of friction.
Vinay in that case i hope the cds are not wiped on ur pant pockets!!! Hahaha.
Mekr prior to loading u should be inspect every cd (especially in the mumbai rains) for moisture droplets as that screws up the cdp. Many years ago my Sony cdp always showed "NO DISC" during the monsoon and some of the cds (mainly CDR s) even had some wierd crackle sound.When i inspected the cds they actually had moisture droplets on the playing surface!!!!!! This happened in spite of them being in their covers and in a closed CD rack!
Buy some MICROFIBRE cloth and save those T shirts/Banyans!!!!!!!! Hahaha
Or as Kamalji suggested use the cloth supplied with spectacles.BTW kamalji am off to buy some Brasso/Silvo as the shops open as i have a few ancient cds which have scratches and skip at the same point everytime!! Hope it works.
Best Regards

It is very good that there are so many suggestions, the do's and don't's.
I can never even dream of wiping the DVD/CD on pant pockets, i try to take the best of precautions.
I handle the DVD/CD near about the way kamal has written, in-fact the greatest thing is that I never hire DVD from the library, my all 200 DVD's are original, and I never lend my DVD's whosoever it may be, my theatre room is always closed so there is no question of dust and related, not to forget that i stay on the 10th floor and than every 15 days the room is vacuum cleaned.
At the end of the day I am always learning from you people on various aspects of av entertainment and precautions, etc.
The cleaning of hands in the pockets is a great idea, you stand only to benefit and nothing to loose, after all, one does get fed up with the routine of going to the basin and cleaning the hands.
Thank You.

Did it work for you, Dinyaar?
If you have'nt yet attempted it, I can post detailed directions on how to go abt it, w/o jeopardizing the CDs.

Kamalji,
Recently my DVD player swallowed a super cd of mine. Had to open the case and found the cd stuck and had to remove it manually. Unfortunately its badly scratched and now skips on the same tracks every time. I tried Brasso on it but it still skips.
Please post detailed instructions at ur convenience. Will be highly obliged if it works as i dont get this CD here.
Thanks in advance.

Fixing Scratched CDs
A simple and safe-to-do-at-home repair for scratched and scuffed CDs
When CDs first came out, there was a remarkable amount of sales hype about how indestructible they were. Those of us who work in radio stations soon found out! CDs are easily rendered unplayable by a small scuff or scratch to the playing surface. Fortunately, these minor abrasions can be easily fixed.
I'm making the distinction between scuffs and scratches because they interfere with the laser tracking and reading mechanism in two different ways:
a scuff mark renders the surface of the polycarbonate milky, rather than clear. This diffuses the laser beam, making it impossible for the tracking mechanism to locate and focus on the pits which carry the sound and tracking information.
a scratch which runs at an angle to the track usually poses no problem for the tracking mechanism. Indeed a well adjusted CD player should be able to track a disk on which a 1mm strip of black tape has been stuck - providing it is stuck on radially. But if a scratch is approximately tangential or circumferential, it can obscure the track below for enough time that the tracking or error correction cannot cope.
Both scratches and scuffs can be removed by the same method - by polishing them out using Brasso. Engineers have been using Brasso as a polish for plastics ever since it was released as a polish for brass.
Use the Brasso in the normal way. A drop or two is usually sufficient (one tin will last you a lifetime of great listening!). Use a soft clean cloth to rub the affected area with the Brasso until the mark is almost gone. Polish scuff marks radially. Scratches are best handled by rubbing along the direction of the scratch. With a scratch it usually is not necessary to polish it completely away - just clean it up enough for the laser to be able to see through it.
Finish up by letting the Brasso dry on the surface, then use a fresh soft cloth to rub it off. Just for good form's sake, do this last stage radially. Remember radial scratches won't generally interfere with the tracking mechanism.
When trying to work out which scratch is to blame for a mistracking, keep in mind that ones at an angle to the direction of rotation are not likely to cause problems. Also keep in mind that a CD plays from the inside out, so that a problem on an early track is more likely to be near the centre than the edge.
So far I have not found a scratched or scuffed CD I cannot fix using Brasso. I hope it works for you too!
