Replace inner sleeves on used records?

Records a commodity ? With everything you’ve to buy, set up, and put up with ticks, noise, static, if you buy um use um lol. 

I have some records that have been in discwasher plastic sleeves for over 30 years! No sticking to vinyl....pristine as the day I bought them. Paper sleeves suck. 

I just keep the original sleeve.  If it's paper that's fine.  If it's cardboard, I clean the record and put a Nagaoka sleeve inside.  There are few of these; they were popular on 1970s rock.

When I clean a record I put it inside a Nagaoka sleeve, inside the original sleeve.  Nagaoka sleeves are too thin to properly protect the disc.  They are sold for their disc-friendly inside surface in long-term storage - some of our vinyl is 70 years old now.  Incidentally, many early CDs now no longer work.  Perfect sound forever only on LPs.

These practices identify the discs I have cleaned.  I have never cleaned any disc more than once and probably less than 10% of my collection.  I clean them only when I can hear noise, on a Nitty-Gritty.

If I believe the inner sleeve to be original, I keep it and place the LP in a new quality inner sleeve.  Both usually fit inside the outer sleeve.

@kenrus , I only keep them if there is important information about the recording on them. Otherwise, they are tossed.
