"The topic of properly cleaning vinyl has been discussed for decades with a consensus adopted that dictates that all LPs should be subjected to a high quality vacuum machine with a variety of recommended fluids. This review has now also been posted here. I purchased and reviewed the DeGritter ultra sonic cleaning machine. More recently, in 2020, a Part Four became necessary. Paul has promised future updates on his article when necessary. Paul's article was originally posted in Positive Feedback. Meanwhile, Part Three is an article from Rush Paul, who has more experience with ultra sonic cleaning than anyone I know of at this time. I will also provide more US cleaning protocol details, and even include some pictures and relevant links. I will then discuss my own sonic results, as well as the specifics of the actual models and machines that were used. I will first go over my personal record cleaning history. In Part One (below), an associate, with the most US experience, will discuss ultra sonic cleaning in general, along with some observations of the actual results.
I decided it would be best to make this a three part report for now. First my associates, and then I, used the Ultra Sonic method and we can now report the results. In contrast, we have had decades of experience using "traditional" record cleaning machines, which first apply cleaning fluids to the vinyl and then vacuum dry the record, all at once or groove by groove. Until 2016, neither I nor any of my associates have had any direct experience with Ultra Sonic Record Cleaning (US).
