Just a few more thoughts on Vinyl cleaning systems out there:
I just sold my Spin Clean Vinyl Record Cleaner for about what I paid for it around $100 (used with 1/2 the cleaning fluid gone). Clearly there is demand for clean vinyl.
I'm not out to bash brush cleaning systems, but I am convinced they are worthless for restoring sound. Brushes remove exterior dirt and grim only.
My 5 L ultrasonic cleaner cost $125 and the DIY setup maybe another $25, the disco ball turner is a plus and minus as mine rotates at 3 RPM, but for better cleaning I am using the turning device to position the vinyl so that it sits in the cleaner 5 min to cover 1/3 of the vinyl at a time.
I experimented with heat at around 40 Degrees Celsius and 2 tsps of Isopropyl Alcohol per gallon of distilled water, this seemed to clean above and beyond the level I had achieved before with just distilled water at room temperature.
I used the Spin Clean Record cleaner on all my records and heard very little change from the baseline static and pop that was on the albums.
The Ultrasonic cleaner took my 1977 original vinyl Cheap Trick album "In Color" and made it sound brand spanking new, seriously.
Getting to the dead wax is an issue with the 5L, so if I did it again 6L might be better for immersion. That being said, I took my original 1985 Dire Straits "Brothers In Arms" which is a long album and grooves close to the label, so after an Ultrasonic cleaning, the sound is great to the point the cleaner did not reach.
I recently bought The Beatles Mono Original 1964 "Help " which was used but had no scratches or obvious defects and after an Ultrasonic cleaning it had a very clean sound,
I am still using a static brush prior to play.
I recently changed my Technics 1200 MK2 from the Ortofon Super OM40 cart to a Ortofon Bronze cart, note less surface noise and the weight of the cart seems to pull better sound off the vinyl.
