MFSL inner sleeves

[sombunya]

I've placed pretty much my entire collection in these, 2700 or so discs. When I pull a disc out to play it I see a sort of haze on it. It isn't smooth over the entire disc, it looks like a wrinkled sleeve "off-gassing" for lack of a better term.

It cleans right off when I use an Orbitrac and a mixture of 80% distilled water and 20 % isopropyl alcohol. I'm not liking this and wonder if anyone here has experienced this or has a comment on MSFL inner sleeves.

Is it on all lps or just some?

Unfortunately this has happened to mofi sleeves before. There are a few threads on Steve Hoffman forums.

Not sure if these are new mofi sleeves or older ones, but you need to get rid of them, clean your records into new sleeves.

IMO, mofi sleeves have always been overrated and flawed with these hazing issues. There are plenty of better and cheaper options.

Personal, I find el cheaper poly sleeves fine for albums with inner lyric sheets. I use covers33 polylined paper sleeves for any records that don't have lyric sheets - they have cut off corners for easy insertion and removal.

Good luck.

I can’t say 100% that it is on all of them, but the sleeves that are about 5 years old, aim noticing it there.

At 40 cents per, that’s around $1000. Kind of sucks to waste them but I like my records more.

One more thing; I like these inner sleeves because some LP’s use shiny card stock for inners and the static grabs hold and won’t let go. I suppose I’d settle for an acid-free paper if it didn’t have a hole in it. First world problems.

I have just about all my lps in these inner sleeves and I would be very upset if they left marks on my lps.

yes they are expensive and definitely shouldn’t leave marks on the lp.I am now worried, I might have the same problem as most of my lps have these inner sleeves.

How could a company like mobile fidelity sound lab do this.it’s bad news for there reputation.

I purposely left the glare to accentuate the issue. Again, it cleans right off and leaves a shiny new surface, but this is still bad news, I think.

As I said, I use a cheap, Allsop Orbitrac to give my records a quick wipe. I use an 80/20 distilled water/alcohol mix and it comes right off. Not like it’s etching them.

I sent a message to MFSL about this. We’ll see what they say, if they reply at all. Also, I’ve used some generic inners and it’s not happening with them, fwiw.

 

[sombunya]

Short follow-up, I heard back from MFSL.

They said they had a few other reports of this and it is most likely excessive humidity or some such nonsense. They obviously didn't read or ignored my message when I pointed out it's only their sleeves that are offending. I wouldn't expect much more from them.

So now comes the process of finding and removing them. I've used inexpensive inners with no problems. And so it goes.

Disappointing response from mofi, but not unexpected.

Imo their sleeves are for audiophools and have thought that for many years.

Good luck cleaning and re sleeving all your records with cheaper safe inner sleeves.
