Ultrasonic record cleaners

@mijostyn

More thorough ultrasonic cleaning following many of the recommendations here did make my noisy records much quieter. . .(but these were mostly sealed records, without a scratch that played very noisily (tons of static-type noise (from what? maybe the plastic from the inner sleeve deteriorated onto the LP?). After noting significant improvement, I put a couple through an even longer cleaning process, and I’m curious to see if I can make them even quieter. . .

"Laboratory grade" means that it is standardized, and validated to perform as described.  Consumer products can otherwise make empty promises.

Based on my initial experience, the first clean is as good as the second clean, and the static-type noise is still present on those noisy LP's.  The first clean probably decreased the surface noise by 50-75%, and made them listenable, but unfortunately, the second clean didn't do any better. 

@cleeds , I did not say a dirty record, or a noisy record that is dirty. I said a noisy record of which there are many. I could have been more specific and said a noisy record that is not dirty. IMHO anybody whose records are so dirty that they are noisy should hang it up and stick with digital sources. 

As far as record cleaners are concerned I am of the opinion that vacuuming the record dry is a major advantage. Each cleaning should be done with fresh fluid. Reusing fluid, even if it is filtered is a bad idea as a filter will not remove substances that are dissolved in the fluid and may leave a film on the record. So, in the world of mijostyn any method that uses the same fluid over and over again is rubbish which tells you what I think about most ultrasonic cleaners. 

@lewm , Laboratory grade? I wonder what laboratory that would be. We had one in grade school where we dissected fetal pigs. Just another marketing term to make you think you are buying something special which usually means you are not. The real McCoy does not need to resort to such terms.

Um, isn’t that’s what rinsing is for?

’Laboratory grade’ is the kind of stuff sold by a laboratory supply company, which is certified to meet it’s specifications. It’s more expensive because consumer grade stuff could be a complete fraud and no-one would know the difference. Labs have the ability to test what they buy, and if it doesn’t meet spec, well, the MIC does have recourse. Think ’hospital grade’ power outlets, mil spec fasteners.
