Good ol Disc Doctor Miracle wash should do the trick Jay. If you're feeling high on DIY there's the usual 25% Isopropyl Alchohol, 75% distilled water and a few drops of windex mix. Finding lab grade isoprppyl alchohol can be a bummer though so I just buy the Disc Doctor concentrate and mix it up later.
I have a bottle of L'art du Son but haven't gotten around to using it since the miracle wash works well enough.
no apparent damage with isopropyl kach, knock on wood, ethyl however........SERIOUSLY bad news! Used ethyl once back in the 80's, took away the vinyl's shine and made the few Lps I cleaned all crackly.
