There is a filter that seems to work well.
Also, it seems obvious that one would not put a record in the machine that was completely filthy. I don't. I don't want the cleaning solution contaminated with a lot of dirt and grease.
The whole point of the ultrasonic cleaner is to DEEP clean inside the grooves in a way that can't be done by any other method. Brushes have bristles that are too large to reach every crevice in every groove in a record.
If there is significant dust, I blow it off with compressed air, then spritz with distilled water and wipe with a paper towel. This happens with almost every record. If there are finger prints or other visible gunk, I use isopropyl alcohol on a paper towel to clean that stuff off. In fact, I ALWAYS wipe the lead-in groove and outer edge of the record with a paper towel wetted with isopropyl alcohol. There are almost always finger prints on the outer edge of any record that has been used.
For the same reason, if I owned a vacuum machine, I would not put a filthy record right on the platter. A lot of the dirt from the record would get stuck on the platter and contaminate the other side of the record. Of course, you should get that stuff off the record before it touches your cleaning machine.
But how many people think about what they are doing? How many users place their records in the cleaning machine remove the clean LP and then proceed to contaminate it by wiping it with a paper towel? Or with a cloth?
The only way to ensure that the LP is really clean is to air dry the record with filtered air. I know this is getting crazy but when we are talking about $4K cleaning machines, all bets are off. The LP has to be suspended from the center hole and filtered air blown on its surfaces to ensure you are not transferring any particles that you took the trouble and expense to remove with the ultrasonic bath.
I use a set of 8 different cleaning brushes plus a clean platter mat to keep the clean side of the LP from getting dirty again when I flip over a record to side B, during my vacuum cleaning ritual.
I have seen videos of people demonstrating the use of ultrasonic cleaning machine and then they take the newly cleaned, but wet, LP out of the tank and proceed to wipe it with a supposedly clean cloth. How long will that cloth stay clean? How do you know it is really clean?
I keep an older Nitty Gritty type machine handy to vacuum clean my cleaning brushes. The upwards facing vacuum slot is very handy to clean the cleaning brushes. I have also seen people use other smaller brushes to brush off cleaning brushes and I wondered exactly what they were accomplishing by that action.
Way back during the Discwasher days we received a small brush to brush off the Discwasher cleaning pad. All those years ago that seemed stupid to me. All you can hope to do is to move around and transfer new dirt to the clean pad of the Discwasher with that kind of action.
It seems to me that we have to use clean room type precautions in order to clean LPs. Any particles in the LP's grooves will likely be audible so extra care must be exercised to remove all dirt and make sure it doesn't get redeposited on the LP. That turns out to be a difficult thing to accomplish.
I will still wait until I read that they have addressed the cleaning fluid issue on ultrasonic machines. The one that you bought has been reviewed but I have not read that the filtration is sufficient to remove all particles. That would take a multistage filtration unit.
Maybe I am wrong (and that's a common occurrence) but the LP cleaning machines are only part of our cleaning regimen and we could use more Help. I watched a video of a custom machine, that someone built, that included a filtration unit plus a forced air drying step.
It was an impressive video where the LP was guided through the entire process without being touched by the user. That is a machine that I would buy. If the LP gets cleaned, the cleaning solution gets cleaned and the LP gets dried, all without reintroduction of any dirt, I feel the LP cleaning process is finally addressed.
