The World's Best Record Cleaning Machine?

Getting a review sample of this unique ultrasonic record cleaning machine took years because apparently the small German manufacturer could not keep up with demand. I’ve heard from a few sources that reliability was not high during those early days but that now that’s been sorted out as has manufacturing capacity.

This compact cleaner can be thought of as a very high tech automatic version of the $80 Spin-Clean Record Washer I reviewed last year. That hand-operated machine uses a fluid vat that cleans many records before the fluid needs replacing as does this one. Like the Spin-Clean, the record sits vertically in the vat and both sides get cleaned simultaneously, but before the manufacturer and importer of this $3895 machine have heart attacks, rest assured those are the only similarities!

This device is fully automatic and unlike any other record cleaning machine I know of, it uses ultrasonics and a process called “cavitation” to clean records much like an ultrasonic jewelry cleaner does likewise for jewelry. If you’ve ever seen a tarnished ornate piece of silver go into such a machine and then come out gleaming, even in the tiniest nooks and crannies, you know how well it works.

Here, you slip a record into a slot lined with soft lips that widen on one side into a vat. Push the “start” button and the record shifts slightly and begins slowly rotating (sometimes it requires a nudge). Fluid stored in a chamber below begins to fill the vat while 4 bi-directional microfiber drums adjust their proximity to the record and then begin rotating, spreading the fluid on the record.

Meanwhile the ultrasonic condenser fires up, producing compression waves the amplitude of which is sufficient to break the liquid’s surface tension causing it to tear apart and leave behind millions of microscopic vacuum bubbles that compress or implode creating tiny liquid jets small enough to clean inside the smallest LP record grooves—think of the jewelry model.

This micro-agitation process displaces any contaminants on the record surface. The fluid is then drained through a filter and the rotation slows almost to a stop as a pair of powerful fans dries the record completely. Remove the record and its clean and dry and ready for play. The entire process, monitored by front panel LEDs, takes six minutes to complete.

The designer, Reiner Gläss contends that both surface suction (Nitty Gritty, VPI, Clearaudio) and point suction (Keith Monks, Loricraft) designs rely upon brushes to loosen dirt and contaminants buried in the record grooves and that brushes simply can’t do the job. Worse, he contends, they often press the dirt further into the grooves. Surface suction vacuuming, he contends, often smears dirt across the record surface while the rubbing friction builds up static electricity. Point suction is somewhat less prone to static build up but is limited to one side at a time cleaning and still relies upon brushing to loosen particles embedded in the grooves.

So how well does the Audio Desk Systeme work? It’s the most effective, easy to use record cleaning machine I’ve ever tried. I bought the review sample. I cleaned already vacuum cleaned records that were still noisy and the noise went away. Two examples: my original UK pressing of “Let It Be” and my most treasured classical album, an original Reiner/CSO “Also Sprach Zarathustra” (LSC 1806). Remarkably, the latter looked clean when I bought it but was hopelessly noisy. Repeated cleanings over decades using more sophisticated fluids and machines have made it quieter but finally, with the Audio Desk, it’s just about completely silent. The machine is too.

The six minute cycle is not an issue because it’s all automatic. I went on a record cleaning spree, managing a record 120 records in two weeks. Not having to stand there and clean and then turn over and clean again made all the difference. You have to remove the record carefully and lift vertically to avoid rubbing against the rollers or you’ll end up with wet spots. That only happened a few times.

Downsides? You are limited to the Audio Desk’s fluid, which is an alcohol free, biodegradable concentrate said to have excellent anti-static properties (verified). You add a small bottle of it ($14.75 per, or $75 for a six pack) to a gallon of distilled (or much better yet reverse osmosis purified water like Aquafina or from your own reverse osmosis system) and that’s good for at least fifty records until you have to start topping up the fluid (a flashing LED tells you when that’s necessary). So you mix up a second batch and add as necessary.

The $99.95 microfiber cleaning barrels need replacing every 500-1000 LPs depending upon how dirty they were to begin with, and you should drain and change the fluid and rinse out the filter every 100 to 200 records. I’m out of space now so I can’t answer the other obvious questions from skeptics other than to say that really dirty, crusty used records should be pre-cleaned. I use Premiér! from Microcare or an Orbitrac and I still keep Enzymatic fluid around to deal with moldy records. I’ve never had so much fun cleaning records!

Since the above review was written back in March of 2012 for publication in the June Stereophile, I have l have cleaned many hundreds of records and have not experienced any problems except as described above and then only occasionally.

I have also cleaned many previously noisy records and most of them came out quiet. Amazing. Yes, it's expensive but if you can afford it, you will not regret your purchase. At this point, it is in my experience, the world's best record cleaning machine.

Everyone should have one of these and it's just not FAIR that it's so expensive!

I'm looking for opinions for Loricraft vs AudioDesk.  I have been very close to buying the Loricraft 4DL.  I was actually just waiting for one to come into stock. 

Now that I have read this review, I'm wondering whether I should look into this one. 

You have/had a Loricraft right?  You prefer it to the Loricraft?  I don't think I will be able to use an AudioDesk to test it out so I'm stuck with information from reviewers and users.

Yes, I have the same question. I was about to pull the trigger on PRC-4 Deluxe.

Mickey, I think you have both. I currently am upgrading from a VPI 17F. I like the VPI, but its a constant battle to keep the brushes clean, the vaccuum tube clean, and to remove the static post vaccuum. 

So what's the verdict? PRC or AudioDesk? 

Should I keep tthe VPI around to do pre-cleaning of really dirty used records? 

LOVE this site. Keep the content coming. 

thanks in advance.

A tip for the VPI. Forget the brushes.

Use cotton cosmetic remover pads clipped to nailbrushes with only the center row of bristles, all other bristles rows removed.

Wipe the dust off the record first with a damp rag, then do the wash with your solvent of choice.

Use separate squeezy plastic bottles with nozzles. Forget the VPIs fluid dispenser. Squirt the fluid onto the pad while holding the pad to the records surface.

The cotton pad needs to soak up the fluid too to get a good coating on the record. Wash the record, the cotton pad will gently scrub the record while getting the fluid into the noods and crannies.

Vacuum the record.

The do a rinse with triple distilled water, again using a separate cotton pad.

Doing it this way keeps the vacuum tube pretty clean, just rub off any dust when it dries.

Static is generally not a problem, at least is not for me.

Sometimes I will use multiple washes with multiple pads, the Audio Intelligent
1. Enzyme
2. Super Cleaner
3. Triple distilled water
routine, all using separate pads gets virtually any record clean.

I think Loricraft, VPI, Nitty Gritty etc are misnomers in calling them "cleaning machines". The actual cleaning comes from the fluid and brushes the user wipes over the record. A Loricraft just vacuums away the fluid.

The AudioDesk actually cleans the record with the ultrasonics and brushes.

Mikey can you ask the manufacturer how many transducers the AudioDesk has? Some DIY'ers have been using ultrasonic cleaners for a while and those that have experimented with various models have concluded the machines with more transducers (ie 6 or 8) clean better than ones with fewer. Thanks!

In reading his last sentence of the review, it appears he prefers this to any other record cleaning machine on earth.


Perhpas I'll be able to afford one soon, with all the money I'll be saving in health care.

The Loricraft is a very nice machine. It's quiet and avoids the lips issues of rubbing that can cause static electricity and of having dirty lips spreading stuff on's also very quiet and cleans all record sizes...but the Audio Desk is i a different league because of how it works...

tubeular's picture

I just got an Audio Desk about a month ago, I like everything about it that you do, but I'm finding that on a number of records there is an increase of popping and ticking in the lead-in and, worse, sometimes the outermost playing grooves, though nothing further in than around 1/4".  These pops sometimes do but sometimes don't go away on re-cleaning.  Have you encountered this?  Trying to figure out whether I'm having some problem with the roller mechanism that turns the record or something on the roller brushes that is depositing something on the outer parts of the record, need to be more careful about wiping any drops of residue when taking out a record or to avoid leaving a record in the machine for very long after the cleaning cycle is finished, but none of these things seems to clearly be the problem.  Also writing to Audio Desk to see what they say about this.  Thanks.

I have too the same machine and we had found that previously records threated with gruve glyde or sort of similar records threatment tends to damage the rubber rollers and contaminate them. Replace those rubbers rollers with new ones and clean with a steamer inside before putting new parts inside

what about cleaning non-12" discs? does this machine have a way to clean garage sale 7" and thrift store 10"?





homersoddishe's picture

It only cleans 12" discs.  So, I guess if you get this cleaner, keep your old one too.

Hmmmm, Finally a record cleaner that eliminates most of the fuss, one side at a time cleaning, recontamination, and includes ultrasonics. Expensive, yes but, so are record collections, cartridges, and listening time. Thanks for another informative review Mikey!

Happy Listener! ;^)>

How cool that the record in the machine has your picture on the label.

Gotta love it.

Michael - thanks for a very informative review.  A fascinating machine, but I'm a little skeptical on a couple of points.  

I understand the water + contaminants are drained through a filter, presumeably by gravity.  I would be concerned that this would leave a residue on the record, akin to a ring around a bathtub.  Also, the machine blow dries the record.  Not sure that would be as efficient as vacuum drying, and undrained contaminated water will be blown back onto the record.  Any thoughts?

My thoughts exactly. One cannot mechanically filter used surfactant (detergent) which means this is equivalent to dunking your silverware in dirty dish water, letting them air dry and then expecting them to look clean. I am a firm believer in the ultrasonic principle of cleaning but this product does seem to have some design weaknesses when it comes to drying the record and removing all traces of used cleaning fluid.

To correct the designer of this product, it is not the mechanical brushing action which removes (or claims to remove) the organic contaminants with traditional suction-type record cleaning machines but rather the surfactant properties of the cleaning fluid itself which is why the amount of contact time is important. The brush is simply there to distribute the cleaning fluid evenly over the LP surface.

Michael. I used my Audio Desk cleaner for the first time today.

First up a couple of A1 condition 1953 Maria Callas Seraphims, Lucia and Norma.

These discs are in great shape an have hardly been used.

First I played a side for my wife and we both noted how quiet and free of surface noise it was. The sound was somewhat thin and the soundstage quite receded. But overall pretty good for a 60 year old recording. My wife presupposed that she would likely hear no difference between it pre and post cleaning. I wasn't expecting too much as this was a pretty quiet record already.

6 minutes later while she was out of the room I qued up the cleaned disc and just 2 notes into the first side my jaw hit the floor. All I could think was...she's in the room!!! Now please note I am not a jaw dropper. I've hardly had a jaw dropping experience in audio. Was I hearing things? Was I over compensating for having spent so much on the machine? Anyway I stopped playing the album until my wife returned. I said nothing to her.

After a while I set it up for her to hear. Also thinking that after this amount of time she would probably not notice much of a difference and that maybe I had been exagerating in my initial reaction.

Litterally 2 notes into the track Vivienne looked at me with a face full of wonder and blurted...."She's in the room!" "Surely this is not the same album." "Before it was like she was in another room...and now she was right in front of us."

Night and day! Jaw dropping!

And the effect is just as great on new albums. You can't be prepared for how much of a veil gets lifted after a clean in this amazing machine. I'm still shaking my head.

I have NEVER heard such a sonic improvement offered by any piece of gear. I've owned an original KMAL for 30 years and I now must say it just doesn't hold a candle to the Audio Desk. Crazy good!

But Michael, how do you get an album out without smearing from the rollers?

Mr. Fremer, first thanks for such an informative and entertaining web site. I've been a fan of yours for many years.

I bought the Audio Desk unit this week (arrives next week -- hurray), and wanted to verify one point if you have a moment: When you say Aquafina as a possible water source, you mean the standard issue drinking water brand you buy in markets and gas stations, correct?


Warmest Regards,


mauidj's picture

Dennis... I am using Reverse Osmosis water from our local Water Store. They claim it has solids down to about 3-4 ppm so I recon it's as pure as you can get. (Aquafina averages 4 ppm). Costs just 50 cents per gallon. I pre mix one gallon with the fluid so I can top up whenever necessary.

Enjoy your new is a fantastic machine!

Thanks Ray, I appreciate the tip!

I'll be selling my Loricraft to buy the Audio Desk, if and when I do, but am concerned about the reliability issues I've read about elsewhere. One person I know had his machine fixed twice and advises "keep the Loricraft."

Anyone else with breakdown problems?



anthem68's picture

I, too, am almost ready to purchase this vinyl cleaning wonder. And I, too, have heard of reliability problems. However, I also heard that this was a problem several years ago, but recently the manufacturing process has had an overhaul and that all past issues have been resolved. Can anyone verify this? Have any current owners had any issues? It's a lot of money to spend on something that might eventually break down...

rlw3's picture

Before using the audio desk cleaner on really dirty discs would a simple rinse under the faucet be ok? how extensive does the pre clean have to be?

audiotom's picture

I looked at both machines
Both do a great job on getting down into the grooves and releasing the low level information and better resolving records

The KL Audio is a much more robust machine with a much more powerful motor, none of the operation issues, and doesn't require cleaner fluids or expensive rollers

I traded in my Hannl Mera EL for the Audio Desk, and I'll never look back! I've cleaned only 30 records so far, without any issues.
I just played the original UK mono Beatles For Sale after cleaning it with the AD, and I can honestly say that I hear details that I've never heard before (the percussion on "Words Of Love", to name one, has never sounded like this before). The soundstage is wider, vocals are better defined, the bass is tighter (heard some bass line variations in "Old Brown Shoe" on the Hey Jude album that I'd never noticed!), amazing!
