What is the best way to clean Vinyl?

I tried a few things before I purchased Ultrasonic.  You may think your records are clean but run 3-4 batches through the ultrasonic and look at the dirty water and clumps of dirt on the bottom.  Ultrasonic is not fun and easy in any way.  Mine cleans 9 records at a time and if you are cleaning a lot it takes a lot of time and space.  But it is worth it.  

Ultrasonic seems to be the best. I use a wet vacuum system, which I think are most popular because they work well and a less trouble. I use a German made Nellie after 20 years with a much more budget oriented VPI.

Here's a how-to video that may be of some help.

I prefer ultrasonic. I really like the one-button convenience of the Klaudio, and there's also the AudioDesk. They're pricey, though.

I've used many different ones over the years and admit the Kirmuss did a great job but based on how many steps it took and the time, after a few weeks it just sat unused. Git a Keith Monks unit and it's quick, quiet and does a good job as well, I now clean records daily.
