Fluids....

Audio intelligent #6...when using RCM...otherwise, for a quickie it’s the old discwasher d4...the original, not the new junk....red bottle. Also, Vinyl Revival for a quick manual scrub down.

Keith Monks discOvery with the KM RCM works for me.
If good enough for the Library of Congress, BBC, etc. …
When I apply the fluid with a brush I can see the whitish decavitation. And then the arm and nozzle suck up the dirty fluid one grove at a time. I understand that Better-Records also uses the KM RCM as well (wt the Walker).

I think most products designed to clean or home made formulas used in record cleaning machines all work well within reasonable expectations. 
The caveat here is not the effectiveness of your choice of cleaning solution..... but the effectiveness of the rinse and its ability to remove both the cleaning fluids and the crud loosened when soaked with those fluids plus no recontamination. 
I've owned a Loricraft for decades....with out a doubt the rinse cycles are the most critical for the greatest result.....wash....rinse, rinse,rinse.

A VPI 16.5 and this.

Don’t make it difficult.
