There was a long thread here on mudcat, but I can't find it. Good suggestions!
Can anyone help locate it?

One can clean with mild detergent and water (I use distilled from the grocer-drug store), rinse with distilled. Use soft clean cloths.

If the record is fairly clean, or after washing, I dampen surface slightly with a distilled water mist spray, (drops or excess water removed with clean soft cloth) put it on the turntable and remove dust from grooves with a soft artists brush as the record revolves (I do this before playing any lp in my collection).

When washing, keep the label dry or it may crinkle, etc.
Store records in clean sleeves.

I have never used solvents (alcohol, etc.), so I can't comment on them.
