I used Torumat for years in my VPI to no detriment. I do not chide them for saying to use none but their own because you never know what some crazy glop will do, and then the buyer goes crying back to them. When I used up my Torumat, I switched to only reverse osmosis purified water in the machine, to do an initial two way clean. Then I stop the platter and use Disc Doctor on their brush, followed by a VPI one way rinse and a top off with Last prservative with platter spinning. I tried several problem records I could not clean with Torumat with Disc Doctor with great results. That made me switch.
