Vinyl Sleeves and Jackets

Yeah put mine in a MF sleeve as soon as I take it out of the wrapping unless they ship in a polly sleeve to begin with, then after the said album slows down in my rotation I slip it into a plastic outside liner, the light Japanese ones. For the guy handling an album like a frisbee, that's dumb on so many levels.

I ditched all my outer sleeves; I mean, I just couldn't see the point in encasing every lp cover in plastic.

As for the inner sleeves, I'll wait to slide them into something more than what they came with when I eventually get an ultrasonic cleaner. But that's about 500 lp's away.

I covered all 4000 LPs with a outer Mylar cover. (now with downsizing I have a big pile of outer sleeves!) Since I bought mostly used, which often have dreadful old discolored and damaged inner sleeves... I replace  those inner sleeves with lined paper sleeves.I reuse those when I discard Lps.. I keep a big pile of the junk sleeves so I can sleeve the LP and still save the sleeve I paid money for. I find no need to replace good sleeves just because I cleaned the LP.

All my new and S/H records get a new inner sleeve after initial cleaning (Mofi or QRP..they are the same), and for single and gatefold jackets a 5mil outer sleeve.

I’ve gone through pretty much all of the aftermarket ones. One issue, with some, is shedding. I’m currently using the MA Records inner which I like but it is pricey, and it isn’t easy to handle.
Once a record has been cleaned and re-sleeved (I keep any original inners of value), I don’t reinsert the record into the jacket; doing so not only causes wear but has the potential to create static. Instead, I use a clear mylar or HDPE outer sleeve for the jacket and slide the re-sleeved record in behind the jacket. To protect the back of the record, I can use: the original sleeve, the literature, inserts or other material that come with the LP, or a unprinted aftermarket jacket. It makes for a thicker package when shelving, but it’s my preference.
On the other hand, I have a friend who sends me records on occasion to flatten for him, and he uses those rounded bottom style, very flimsy, but they seem to leave no debris on the record and are very easy to slide back into the jacket.
I still have a stash of some old VRP sleeves.
As to fingerprinting records, the theory is that the skin oil will attract contaminants, and those could potentially add noise if ground into the groove. I clean once and attempt to keep the record clean thereafter. Static is also an issue to be minimized.
