Which fluid should I use

I use RR fluids exclusively after trying most all of the commercial brands and several home-brews. RR proved the very best and for most of the reasons Jfrech notes, especially in terms of it leaving NO sonic signature. I do use a separate brush for the deep cleaner and one each for the two passes I give with the wash. It may be overkill, but I rarely have to give a second wash to any of my LP's after employing two "rinse" cycles using my VPI 16.5.

Taters...I use the super deep clean first, then the wash. And yes, I use separate wands for vacuming and separate brushes for clean vs wash...

I really like the Record Research labs wash. This product is best in my opinion for ease of use and overall sonic performance. Seems to last longer on the record after many plays. Really love the way it cleans up the vinyl and brings out the best in the music. Have fun!
