I use a magic eraser on anything glossy and just a slightly damp microfiber for matte finish. I only do it on thrift store finds for the most part, while in many cases the vinyl appears/sounds unplayed, the records have obviously been stored in less-than-archival envinronments.
What are you using to clean LP album covers?
What do you guys use, if anything other than a damp cloth to clean LP album covers. I like to use the plastic sleeves on most of my albums and want the cover to be looking it's best prior to sliding it into the sleeve. This subject has probably came up before but using search turns up nothing for me.
