I'd be a bit suspicious about all those LAST products too.
@mijostyn I must disagree with you in your blanket condemnation of ultrasonic cleaning. If used wisely, it certainly improves on a vacuum RCM, and by wisely I mean addressing the issue you raise about air-drying. For example, I remove as gross contamination as possible with a Loricraft point-source vacuum machine, mostly to avoid contamination of the solution in the Degritter which follows it. Then I do a distilled water rinse on the Loricraft and dry the record on that same machine. I have experimented with changing the order of the machines and with all sorts of solutions, and I think I have it right now. It doesn't make very much difference whether I use a detergent based solution or an enzymatic one: either gets removed by the final rinse and so residue contamination is not an issue. And the final vacuum drying reduces static from air-drying, so that is dealt with (I admit I still use a Furutech Destat III and a blower brush before each play to be sure.) A record treated like this will usually be silent and can be played a dozen times before needing a repeat clean.
I do agree in one respect though, if the Degritter breaks down (as they seem to eventually do) I shall likely continue with the Loricraft alone. It seems to do all the heavy lifting as about 80% of records will be silent when cleaned on it without the Degritter, as I discovered by using it for twelve years before I added the Degritter. That has made a record with surface noise quite the rarity now, the exceptions are usually older records that have had a hard life with previous owners or with me before I learned that cleaning was so important.
