Glue from inner sleeves leeching onto records


I have gone through some of my collection of 'audiophile' records that were pressed at RTI pre-2010 (Cisco, Analog Productions, Classic Records etc.) when they used an inner sleeve that was made up of paper on the outside and a poly liner on the inside, which was held together with a line of glue about 1" from the perimeter.

I have found quite a few records with these sleeves where the glue has leeched onto the vinyl. I tried cleaning it off at first with my Degritter RCM, but it did not remove much.  I also have a Keith Monks Gemini RCM, but it won't be ready for use for a little while.

I was curious if maybe using one of the 'glue' record cleaning process might work for this?  I never thought I would try such a cleaning method, but it may be the best for this scenario?

Has anyone had this issue and found a successful way to clean the glue off the records?

Thanks

Wow, thought I knew all the reasons to avoid "audiophile" reissues, and now one more! Tom Port looking better and better all the time. 

Glue calls for chemical removal which calls for research and testing different chemicals. Xylene, toluene, etc. Or maybe you get lucky and something like Dawn dish soap will work. There's a wonderful organic cleaner Citra-Solv that has worked on an amazing number of seemingly impossible to clean things like tree pitch, you might try that. There is also 3M Bug and Tar remover. A lot of these will get your glue off. The question is can they do it and still leave the record in good condition. Test a little spot on one of the least important records until you find what works.
rich121, I have never seen this happen. Is there some source of heat by the records?
You obviously need to replace the liners. Take apart a sleeve and expose the glue. You have to find a solvent that will dissolve the glue. First try isopropyl alcohol. Use either a clean cotton or microfiber cloth. Saturate it with Alcohol and wipe gently. If the glue comes off you are in business if not you have to move to a non polar solvent. A chlorofluorocarbon will work best. "Last" the record preservative is one but at $50 a little bottle not so practical. This  https://shop.advanceautoparts.com/p/crc-brakleen-brake-parts-cleaner-19-wt.-oz.-05089/7060459-p?prod...= is very practical. I have used this exact brand on a record with absolutely no deleterious effects. Test on the sleeve first. If it works remove the bulk of the glue with your cloth always moving to a clean area of the cloth. Then spray the record directly to rinse it off. It dries very fast and will not hurt the label. You might want to do this outside and you will want to wear gloves. After the record dries give it a run through your ultrasonic unit then put it back in a new sleeve. Good to go:)
This was not uncommon with records pressed by RTI pre-2009... Almost every one of my AP Blue Notes have this issue... Cisco also is known to have this issue and some Classic Records releases.
mijostyn, rich121,

Be careful with  CRC Brakleen - it contains mostly  Tetrachloroethylene (Perchloroethylene) which is a chlorinated hydrocarbon (most CFCs solvents stopped manufacture 1996).  If you use CRC Brakleen read the MSDS carefully -  http://docs.crcindustries.com/msds/1008012E.pdf.  The solvent PERC (once used by many dry cleaning establishments) is a strongly suspected human carcinogen and while non-flammable if exposed to heat `~600F can form deadly phosgene gas.  PERC as addressed in the MSDS should only be used in very well ventilated areas.

@millercarbon  I'm sure Tom and your credit card company will be very happy to hear this 😁



@rich121,yes have seen this myself too on a few earlier releases from Cisco and a few Classic records. Once I found this on one, ditched the inner sleeve on all of the records from that vendor and replaced with new discwasher type sleeves.

Also of note if you have any of the music matters 45 rpm pressings with the light pink inner sleeves, get rid of them and replace with something better. they will leach plasticizer deposits on the vinyl over time,.

if you have any London Decca records with their original sleeve, (the clear plastic pvc type) replace those as well, they will leach plasticizer from the sleeve onto the vinyl.

As far as removing it, pretty tough....have not had much luck with any mild solvents.

If you find something that works, please post....
thanks
