@terry9,
I just changed to brand new distilled water. The closest I can measure, I’m using 256 oz. in my tank when it’s filled properly. I put in 2 oz. Versa-Clean, & just slightly over 1 tsp. of Photo-Flo. The first lp I’m cleaning is a brand new Procol Harum "A Salty Dog" MFSL. My settings are..40 minutes / 45 degeees C / RPM = 1 revolution every 7 minutes.. This is a much lower ratio than you suggest...closer to 100:1. I do steam first with the Audio Intelligent down with dirty concentrate. At this ratio, great rinsing is still needed.
I forget,, do you use Photo-Flo in your mixture? For right now, my heroic rinsing is another steam of the lp after a US cleaning. That’s pretty "heroic"!
