Treating records with LAST preservative

Inna, I've never used LAST preservative, or any other kind of preservative treatments on my records.

As a record collector for many years, I did some research on the recommended storage procedures, and found that those worked quite well with no risk of unknown fluid effects.

The most important things that I have found for maximizing the LP is:
1) Storage on edge in reasonable quantities - so there is not any stress on the LP from stacking or leaning with weight on it.
2) Using a virgin vinyl or rice paper sleeve that can't leach any plastic stabilizers out of the record vinyl.
3) Using an outer sleeve to protect the record jacket, and placed on the LP with the jacket opening inside the outer sleeve to act as dust baffle.
4) Normal, regular cleaning of the disc with a good record cleaning process that doesn't include strong vinyl solvents.
5) Using a carbon fiber brush to keep dust off between wet cleanings.
6) Keep the stylus clean.
7) Keep the temp and humidity in normal living parameters, and keep the records out of direct sunlight.

I know that others use Last and have had good results. I have not, and cannot make a meaningful statement regarding its use over the long term. Frankly, I worry somewhat about the long term effects of any additives to the surface of my records.

You have to be careful with Last. It will definitely cause some types of vinyl to deteriorate sooner. On other types of vinyl, you will increase longevity and prevent deterioration. I ruined several Reference Recordings using it --- much noisier when done. In my opinion, the use of the preservative is not that valuable, and I quit using many years ago. Keep your vinyl clean with a vacuum record cleaner and appropriate solutions. I hope this helps.

Tom said it all. I do however use Gruv Glide although at a much lesser level than the instructions say. It's a must for Linn owners because without some type of anti-static the felt mat will lift with the record in the winter which is a major annoyance. I don't know if it will damage the vinyl with time but doubt it. It's easily removed with a normal, quick wet cleaning on my machine. At least that's been my experience.
