vpi record cleaning machine fluid

I used it full strength; I don't think that bottle was meant to be diluted, only for squirting the fluid on the record.  You just refill it when it's empty.

I was a VPI dealer for many years.  The bottle that comes with the unit is NOT concentrated.  They also, at the time, sold a much larger bottle of non-concentrated fluid, (like a half gallon or gallon), but it became to much money to ship, so VPI went to a concentrate.

While the VPI fluid is okay, IMHO, the Audio Intelligent #6 fluid is better.  I also like the L'Art Du Son concentrate.

YMMV...
