I think, there is no "best" fluid. A lot of users think, to remove some dirt out of the grooves, NASA science is neccessary. There are so many fluids out there and honestly, they do the job. Some use multi step fluids and think, that's it. But when you use other fluids 4x, you will get same results :-)
At the end of day, the secret is the removal out of the grooves. Point nozzle is unsurpassed, but it needs time. AIVS, L'Art du Son, VPI, Walker, MFSL...use what gives you the best feeling :-)
(With modern records which have damaged grooves, tics and pops, nothing really helps. That's the way it is)
