Back on track here, hopefully, I can relate some LP cleaning experiences. I started way back when using a mild dishwashing soap solution and rinsing with tap water followed by towel wiping, then going to a Discwasher brush onto which a cleaning fluid was applied, then 25 years ago going to a Nitty Gritty vacuum cleaner. With this I tried various alcohol-based and non-alcohol-based cleaners, then enzymatic cleaners, the last of which seemed to work best when followed by a purified water rinse.
Recently, though, I went to a KL Audio ultrasonic cleaner and this has made a big difference in both surface noise and fidelity of the records I clean. The problem with the KL is its cost but there are some others seen here on the Gon that use a simple motorized spindle to spin the record through a relatively inexpensive benchtop ultrasonic cleaner like those seen in a laboratory. In many cases the use of my KL Audio cleaner has allowed me to buy somewhat lesser quality records and then resurrect them. If you have a large investment in LPs and a high-end system, I would highly recommend the purchase of such an ultrasonic cleaner.
