Audio Desk Ultrasonic Record Cleaner Onwers?


Howdy,

Reaching out to other Audio Desk owners here. I am wondering how often do change the rollers, filter and the fluid. Do you go by the pamphlets  or play by ear (no pun intended). I waited for about 150 records before changing the fluid and filter and the fluid was SUPER nasty. I think I will do 100 records now but of course, it depends on how dirty the records are to begin with.

Also, the pamphlet says "not to leave the fluid in the machine for long", which is completely subjective. If you have to drain the system every week (which by the way, is no simple task for a single person) how long do you have to wait to put it back?

I am going with the 100 interval for changing the fluid and the rollers and the filter. I figure if they figure 150 is the normal interval, Then I am just assuming that the last third of the life of the rollers in the fluid would have fairly dirty water and rollers. In relation of the cost of the machine versus my record collection it’s a small investment change every hundred. As far as the draining I have to agree it wasn’t a very well thought out design, so I have discovered that three-quarter inch PVC pipe fittings work. I have a couple of the fittings but haven’t come up with a suitable valve yet.What I do in the meantime is turn on the machine and let it run one cycle without a record to keep things lubricated, wet and mixed up look for longer periods I drain it into canister. Otherwise I am very happy with the machine and convenience vs the VPI 16.5 I used for years.
How often you change the fluid will depend on how dirty the records are to begin with. My record collection is in already excellent condition, since I have used a vacuum cleaning machine since the 80's. Even so, I change the fluid every 50 records. I cannot imagine cleaning a record in dirty fluid, then allowing the machine to air dry all that crap back onto the record. I do not use the drying cycle for that reason; instead I shut the machine off once the cavitation is finished, then rinse the record in a Spin Clean, then dry with a vacuum machine. A lot of work but my method leaves zero residue on the record when finished. Yes, I'm crazy like that :-)
@theo : "In relation of the cost of the machine versus my record collection it’s a small investment change every hundred"

Agreed. I was testing the waters so to speak. Now that I know how dirty it gets with 150, I will do 100 and change fluid and inspect how the rollers and filters look.
@seasoned "I do not use the drying cycle for that reason; instead I shut the machine off once the cavitation is finished, then rinse the record in a Spin Clean, then dry with a vacuum machine"

Very interesting and it makes total sense to me. I will have to try your method for sure!
I have had an ADS Vinyl Cleaner for 5 years now and use it regularly.  I remove the filter and rinse it about every 25 lp's or so and change the fluid every 120-140 lp's.  The only time I ever get excessive "crud" in the machine is when I clean an LP that someone has used Last preservative on or some other graphite based product which comes off completely with the Ultrasonic.  I always use the forced air drying as you never have static buildup that way on the LP.

It doesn't make sense to me, at all.

We all know that the AD cleaner and the Spin Clean use fluid over & over that our records are exposed to in their respective cleaning methods. The Spin Clean fluid has an additive that (supposedly) makes the "crud" fall to the bottom.

The AD cleaner...It's great to clean the filter and change the fluid, but there is another problem... the crap that forms on the inside of the cabinet that can never be cleaned away completely.

Another reason for the DIY method.
I use an Audio Desk machine and love it for the simplicity. I suppose I change the water every 70 LPs or so, mainly because I go slow these days and by that time it feels about right to make a change. A few points: 

I agree that the machine appears to leave a residue and that you can get better sound by rinsing the LP afterward with pure water and a vacuum, or by using a VPI machine instead, for instance, with good fluid like the Audio Intelligent stuff I use. I don't like to admit it, but I do hear an improvement with the AI fluid over the Ultrasonic. But again, it's the simplicity that counts for me - if I had to do every LP on a vacuum machine I would never get around to cleaning my LPs. And having invested money in some decent carts... 

You can clean off the brown crud that accumulates on the brushes after extended use. I do it by removing the two rollers and rubbing them together while dunking them in distilled water. Each one cleans the other. They look great after this.  Might save you a round or two of purchasing new cleaning brushes. 

on the frequency of use: According to the rep in PA you should clean records every three weeks at least, if you keep the machine filled with fluid. Otherwise the water can degrade the water pump, a problem that's prevalent with the earlier, original model machines. I learned that the hard way when my old one had the dreaded water pump breakdown.

My Spin Clean rinse step does not use fluid or brush insert; just deionized water with a few drops of isopropyl.That is followed by a final rinse on the RCM using Reagent Grade water and vacuum.
I have had my AD cleaner now for a couple years and have cleaned hundreds of records. I do not have crud on the outside of the machine; still looks new.

I encourage ADS (or KLA) users to spend $15 on a TDS (total dissolved solids) meter and check the machine’s solution before and after each cleaning session. The solution on the record when the fan starts will evaporate, but whatever solids are in the water will dry on the record.

Don’t change solution based on a certain number of records - change it based on how dirty it is.

The solution gets dirty in a surprisingly short amount of time. The unit’s passive filter helps but only marginally so. Plus, the tank itself retains gunk (solids) record after record after record. All of the single slot desktop machines need active filtration with a fine-grained filter.

The ADS and KLA are okay - anything that encourages record cleaning is for the better - but as RCMs, they are second rate. I say this as an owner. I believe better alternatives are available for the same or lower cosr.
P.S. yiu can put the ADS rollers in a washing machine gentle cycle.  Rinse them thorougly afterwards and air dry.  Keep a spare set of rollers on hand for comparison.
