The cleaning of an LP jacket


I hadn't bought a used LP in a while, but did today. The LP itself is pretty clean, and will be even cleaner after it gets washed. But the cardboard jacket (cover) is a little nasty, more so than the ones I usually buy. What methods and products have all ya'll used to get them clean? With my normal not-so-dirty ones, I've always just set the jacket on the kitchen or dining room table and rubbed it with a folded paper towel. This cover looks like more drastic measures might be required to get the grime off.

Thanks slaw, I’ll go to the website.

@pryso, speaking of which, I received an email with a 20% off coupon from Barnes & Noble, so went to the store in Portland to see what their LP section looked like. On some titles B & N has versions exclusive to them, different in some way from the standard release---colored vinyl, etc. I found the Marty Stuart And His Fabulous Superlatives’ Way Out West LP with the cover autographed by all four members. They actually sat down and signed a pile of LP covers before they were shrink-wrapped, for distribution to Barnes & Noble only. Kinda cool to have, and at 20% off!

Thanks @cleeds, your link worked.

Well, I think if one is a (member) they'll get a % off ( Barnes & Noble)'s purchases.

To each his own.................wait "it's plain to see, to walk alone".....

Recently received an order from Sleeve City, so I don't believe they are Out of Business.
