how to clean nasty, dirty finger prints on LPs


I tried with Distilled water/Alchol/detergent combo, Emgzine, steamer, scrubbing. none of them works.
any suggestion?

I applied with 100% Ethly Alcohol on a piece of face tisuue, rubbed on the finger prints, rinsed it with distilled water, repeated a couple of times. most of finger prints are gone, or get thinner.
However, I feel the sound is getting bit thinner also now comparing to the other side I don't clean. It could be just me. :-(
Xctian,

I think some of the reports of Windex being damaging to vinyl may be caused be the tendency of those who use Windex on their records to also use paper towels. The paper towel will leave behind tons of paper fibers which is quite noisy and will increase record and stylus wear. I haven't noticed any adverse effects from the Windex. I feel using a small amount is safe, not sprayed directly on the record but onto the cloth. Followed by a good rinse (I usually use the Windex before my entire 3 step cleaning) I don't see much risk of damage.

I use the Audio Intelligent products, and sometimes the steam cleaner. On it's own, that regimen is not enough to remove thick, oily fingerprints.
USE RUBBING ALCOHOL WITH A CLEAN CLOTH OR PAPER TOWEL. THIS ALSO APPLIES FOR DIRTY RECORDS BUT UP TO A POINT. LIGHT DIRT IS EASILY REMOVED BUT IF THE RECORD IS TOO FAR GONE, IT NEEDS TO BE REPLACED.
