I remember ticks, pops and the sound dried beer sounded like on 45's and 60's , 70's LPs. These I still have an will be resurrecting them now I have time (retirement).
I probably bought Australian versions of the best LPs, made of the cheapest Vinyl. I now have time to scour the collectors bins for some quality replacements and a good quality cleaner. US$4000 for a top shelf ultrasonic can buy a lot of LPs I can put in the dishwasher (kidding). But then has any one tried a dishwasher, no soap?
