Ultrasonic cleaning

I use a Degritter with AI's ultrasonic record cleaning solution

I use a generic ultrasonic machine (Amazon special) but use the Degritter brand cleaning solution. I had reached out to them and they told me their solution could be used in any ultrasonic device. I also use a Discwasher just before playback, with Mobile Fidelity One cleaning solution, since I ran out of D4 years ago. 

I use plain distilled water with no additives in my DeGritter.... 

I've had such a good experience with Neil Antin's mixtures to produce a Cleaning Solution, it is more than worthwhile familiarising oneself with this option. 

I also use a generic ultrasonic cleaner from Amazon 

I use distilled water and a capfull of Spin Clean Record Washing fluid. 

I heat the water to 30C for the cleaning.  

For what it's worth I precede this with a dry cleaning to remove as much dust out of the grooves and I follow it by a traditionally Spin Clean to get anything stuck in the grooves. Overall I can take a filthy antique store record and nearly fully restore the original sound.
