@robjordan  Rob, Yes, the Dehypon is ok to use as wetting agent in this mix. As far as the crystalline citric acid, this is where I stop.  I am not getting into the formulating of products.  The DWV + some drops of a nonionic surfactant wetting...

@robjordan, Rob,  The Ecover Zero Non Bio is a good product.  I was able to locate this SDS Ecover-Laundry-Liquid-Zero-Non-Bio-Laundry-Liquid-COSSH-Sheet.pdf and it mostly supports what their site is listing for ingredients.   Essentially as a ...

@wavez,   One step, of course, its called a $3000 Degritter or maybe a $6000 Clearaudio Double Matrix Pro Sonic.  Convenience is expensive.  There is the ~$500 (w/shipping) Humminguru, but to get good results with it you need multiple steps. As...

Best phono stage for Lyra Etna SL cartridge?
@chungjh,Having missed your other post - https://forum.audiogon.com/discussions/vta-adjustment-on-technics-1200g, disregard my comment regarding tweaking of the VTA. 
Best phono stage for Lyra Etna SL cartridge?

@rauliruegas,Please do not bring me back into this conversation.  But, for the record, this is what I said about the SAT:"However, from my perspective as someone with an engineering background, this table is not breaking any new state of the art. ... 
Heat
Very simply, the operating temperature of electrical equipment is X deg F above whatever is the ambient w/o forced cooling such as a fan.  If X deg F is say 25F, and the ambient temperature is 75F, the internal operating temp is then 25F + 75F = 1...
