I purchased my first quality cleaner, the VPI 16 (now upgraded) in 1982. I played with various solutions over the years. I chose a Kirmuss ultrasonic using just distilled water. No filters, easy drainage, reliable. It works but for the need to dry the LP on my VPI 16, so a great combo for about $1800 new. Unfortunately, the ultrasonic is so good that it reveals noisy records by removing any gunk in the groove that previously hid damage (mostly old used records). Despite the additional LP noise, every LP has improved sonics. That’s what it is all about. With 28,500 LPs and 7,000 78s, this machine works (in conjunction with the VPI to dry).
Since most of my collection is relatively clean, without prior attempts to clean (such as the popular silicone used in the 60’s, etc), just distilled water is adequate and lasts at least 10 to 15 LPs prior to dumping and refilling. It’s simple and it works. No more solutions (last was Disc Doctor with the cleaning, then double rinsing on the VPI-what a hassle).
P.S. I just don’t believe there is a significant or any mold release compound. Maybe I need a $50K+ + turntable with a $15K+ cartridge to hear the difference. Using a VPI TNT VI/VPI controller/Townshend Seismic Sink/highly modified SME IV/Dynavector 20X2L/Zesto Allesso SUT.
