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.
