My experience with Last initially was not good. I found it really deadened the sound, the dynamics of the recordings. It seemed to make them a lot darker. I was cleaning the older records I had purchased more recently and that had surface noise. I used the GEM Dandy record cleaner and then followed with ultrasonic bath and then Groove Lube, which must be used very sparingly and according to instructions. Then, at the end, I applied the Last. I found the initial results quite disappointing to say the least. The records were, however, much quieter and the surface noise was pretty much gone. The Groove Lube left a bit of gunk on the stylus but I removed that easily enough on each side with the Magic Sponge that's been recommended here many times for stylus cleaning. I got busy and then came back a few weeks later and listened to other LPs I had cleaned with this method. Well, after waiting several weeks, the Last preservative was no longer imparting any kind of unwanted sonic effects. The sound had changed completely back to normal. I still have not applied it to the brand new records I've purchased, but I will say that I will continue to use it for older LPs and I might try it on new ones after I've had more experience with it. So I would recommend it then so long as one gives it enough time to fully settle in.
