how to clean nasty, dirty finger prints on LPs

thanks for the suggestions to you all. blowtorch is a bit of overdone. :-)

to Rockvirgo: is alky also called alcohol in U.S.? :-)

to Zargoz: I read from other thread that we need to be careful with Windex, However, it sounds that it works for you. Have you checked your LPs sometimes after you applied Windex to them?

I also noticed that when I used Perfection steamer on LPs, I got a bit of burning vinyl smell. My steamer's noozle was about 4 inches away from LPs.
anyone notice that?

One more thing: I tried to rub it with my finger on the edge of LP. it seems to be working. I am afraid of doing it on grooves so I will do more harm than good.

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. :-(
