Ultrasonic cleaning

I recently started using a HumminGuru with distilled water and it has been working great so far.

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.
