I looked up the video instructions for the Kirmuss record restorer. All I can say is, if you’ve got a lot of time on your hands this machine is for you. There are at least 10 steps in the process, every one of them time consuming. Undoubtedly the results are better, but is the improvement so much better as to spend half a day cleaning a few records worth it?
I’ll stick with the Humminguru.
