Best ultrasonic lp cleaner in 2020 and what surfactant best?

Don't necessarily take me literally about 2 drops but a small amount on that order of magnitude is what I personally use.  Others may do differently and they are not necessarily "wrong".  I use a higher concentration of isopropyl alcohol, maybe 20%; I have forgotten. 2% of alcohol would do almost nothing, IMO.  It would evaporate away rapidly, first of all.

I picked up the Degritter back in August and couldn't be happier.  This is impressive.   Records seriously sound better and you really can turn a dollar record from a garage sale into a keeper.  Highly recommended.  

Hi,what cleaning systems have you used previously?Were you able to find a discount?thanks

The detergent that comes with the degritter is excellent. I have used Kodak Photoflow with my DIY ultrasonic tank but the degriiter's detergent  solution really wets the lp very well. 

How does one degas and what does it do?
Thanks
