It never ever occurred to me to clean an album cover. In fact, I like the fact that the covers show patina that tells me the LP inside was pressed during the vintage era, and/or that I have owned it for a very long time.
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.
