Markd51, I'm sorry, I misunderstood what you were saying by 180 degrees.
Sonofjim, in my experience there are clear benefits of some cleaning methods over others. Years ago I tried steam cleaning to no get benefit. Perhaps I did it wrong. Before the three step Walker Prelude system, I had used Diskdoctor, VPI, Diskwasher, AudioNote, L'art do Son, and several others. When I got the Prelude, I played previously cleaned records and then cleaned them with the three steps. It was clearly audible on all of them, causing me to spend seven days to reclean everything previously cleaned. Then I got Step Four from Walker, not really expecting much. I was shocked at the additional improvement. Just yesterday I found a record that was previously cleaned with L'art du Son. I used only Step Four. Again I was shocked at the improvement. Just to check I did all four steps and relistened. It was much better. In my opinion there must be degrees of "clean."
