It’s been a while since I looked hear. Glad to see the continuation of this thread!
Here’s my current method. As you all may have noticed, I go in steps so I can evaluate things better.
(1) Use Audio Intelligent (Down With Dirty) mixed at 1&1/2 oz per 16 oz of distilled water...spread onto a lp. Then steam off. Both sides.
(2) The US bath.... Eight oz. of Versa-Clean, 1 & 1/2 tsp. of Photo-flo, to the 2 gallons of distilled water in my 6 quart tank. (40Hz)
(3) 45 minute bath at 45C
(4) Rinse at my sink with the sprayer with hot tap water. Then a final once over with a bottle of distilled water
(5) Vacuum on my 16.5 after the lp is dried manually.
Right now, I don’t think I need a 40:1 tank solution as I do the pre-steam method above. Time will tell.
