So goes the urban legend, but my experience is that, mostly, condition remains as it was, and sometimes improves. I now have a permanent TT set up for the job, which I use for records with poor surface noise. Where there is generally a very worthwhile improvement. Sometimes that improvement is permanent, but typically not. Very seldom worse. However, personally, I don't use it for records in good condition, it's pointless. But when I have, have not noted degradation, and Flavio81 (AFAIK) still uses it extensively, as per this thread.
Although it's pretty simple, it's a useful thing to know how to do, but I could imagine it not going well just because it's messy, and process matters. Perhaps hence the urband legend?
I don't know why the hifi press didn't take to it, perhaps it's an embarassing leveller beyond their control, outside the comfort zone, who knows ? The line about muck in the grooves and high temperatures/pressures doesn't cut it though, plainly nonsense. And besides, there is an upside ! And now perhaps with an explanation as to why.
It's not as if dry play is exactly noise free sometimes. And, on occasion, there is nothing to lose and much to gain. These days, I use just distilled water and a tiny amount of surfactant, BTW, and still rinse off and leave to dry afterwards. It's worth it though, when it's necessary.
