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.

Unless they've really messed up the cover, I like previous owners' notes. I have some from the 60s with gift notes which are great.

When I started buying 45's as a 12 year old, I wrote my name on them all, so when we had dance parties I would know which were mine. Don't have them any more, but someone else may, and is wondering who I am ;-).

The UK type glossy jackets are not a problem---they can be cleaned with liquid. It's our U.S. paper ones that don't appreciate getting wet. I've used Bestine (found at art supply stores) for years to remove price sticker glue residue, which if applied very sparingly does no harm. Slaw, where did "the Sleeve City guy" make his recommendation, and what was it? What is the name brand? I agree, bacteria on LPs and their jackets is not something I care for!

@bdp24,

If you go to www.sleevecity.com he has several videos showing various things. The name brands I was referring to are Clorox or Lysol not the store brands. This website seems to not be working right, I'll have to look into it later.
Is Sleevecity out of business?  I just tried that link and saw their domain is for sale.

bdp24, if you were famous I wouldn't mind your autograph, but if you're not I'd rather have the jacket/label clean. ;^)
