A machine does a much better job than hand cleaning. It actually sucks the suspended dirt off the vinyl. Nothing else works as well. Some discs play better than new afterwards ; they came from the plant with gunk in the grooves and we never knew...
You can get away with a cheaper machine if you do more hand work. A manual rather than motor-driven turntable costs less but you turn the platter. More expensive machines clean both sides at once. All of them can do a good job.
There are do-it-yourself designs around. Check at Audio Asylum or the back issues at UHF magazine ( www.uhfmag.com--UHF also sells a quality cleaning solution at a good price ). You need a platter to turn the disc as you apply fluid and scrub, and a wet vacuum with a nozzle that won't damage the disc as it sucks from the vinyl surface.
One tricky point is keeping the vacuum nozzle clean, so as to avoid putting the gunk right back where it came from.
