scrubbing lp with discdoctor brush and vpi 16.5

Two things:
1. You might want to get a second wand for the 16.5 and use it to suck up the first (non-water) fluids. This keeps the wand clean for the final rinse. Alternatively you can use some other method (a clean cotten pad or scott toilet tissue) to mop up the fluid prior to using the distilled water and final vacuum. I only have on wand and use toilet tissue. If you do that, use enough tissue so it doesn't get completely soaked and disintegrate.

2. I always do two distilled water rinses. One often isn't sufficient.

I use disc doctor fluid so YMMV. I got the tips about scott toilet tissue and the second rinse from the disc doctor himself.

BTW I always do the brushing on the platter with the motor off. Leaving the motor off keeps the motor from overheating (it's off more than on during cleaning) and it's better to do back and forth motion than just brushing one direction. You just leave the platter stationary and move around the record, keeping the brush perpendicular to the groove at all times. It's pretty easy. I use a back and forth motion and work around the record 5 or 6 times. It's supposed to be similar to the agitation in a washing machine--you aren't so much scrubbing out the groove as agitating the fluid which does the work. It just takes a bit of time.

I get great results this way but I did have mixed results initially until I fine tuned the method.

I buy only new records. I use the Audio Intelligent 3 step solutions, and I have tried steam cleaning too. But some records, no matter how prestine they look, no matter how long and how many times I cleaned them, they're just plain noisy, and I'm specifically talking about surface noise that's very apparent between two tracks. I know these noise that I heard is not due to my TT setup because I do have some LPs that are absolutely quiet.

So the thing you need to determine is, are you sure the "mixed results" you're getting is not due to the inherent flaw in the pressing itself?

I also do exactly as cincy_bob does. This seems to work best. With all LPs, regardless if filthy, or new, dust=grime will begin to accumilate on the Arm Wand Velvet. Remove after a few LPs, brush clean with a soft toothbrush, rinse with Distilled water, shake excess water, and return to RCM.

With my 16.5 I added a cooling fan, so I can literally run the machine 24/7 without any heat build-up, but for those that don't, perhaps after a 1/2 dozen LPs, drain the recovery tank, get a glass of Kool Aid, or whatnot, take a break, and let the machine rest a few minutes before continuing.

I think all will agree, marathon cleaning sessions get sort of monotonous after so many. I can maybe do 15 at most, with the 3-step AVIS process, and then usually throw in the towel till next time. Mark
