do record cleaning fluids soften the treble?


Over many years of cleaning records with fluids containing a surfactant (not specified) I have come to the opinion that the process leads to a very slight softening of the treble. After cleaning the sound was more"cosy" and less extended in the treble. However I did not get this effect with the VPI fluid that came with my 16.5 machine. It made the sound somewhat drier. Anyone else noticed this /these effects? Any idea why???

Just for the simple fact that your stylus will last longer when tracking cleaned vinyl than uncleaned is cause enough for me to clean every record I play. That and every one I've cleaned has noticeably sounded better without question.

I've yet to hear a negative impact after a cleaning. Perhaps I've just lucked into a effective methodology.
Stanwal and Notec, just to be clear, I am not recommending that anybody play dirty records. If a record is dirty, it needs to be cleaned. Period. My comments are directed to records that are already clean (both visually and in listening) but haven't gone through a cleaning fluid/vacuum process. In my experience, a record that is already clean does not sound as good after the fluid/vacuum cleaning, so I don't do that type of cleaning routinely. I only do it where it is needed.

Also, I use a carbon fiber brush to wipe off the surface of each record before I play it, and I wipe the stylus with a dry brush before I play each record.
My position,experiences,impressions and approach to the issue of record cleaning mirror Salectric's to a tee.
I can understand a solution leaving behind things that fill the tiny grooves that represent the HF information. I'm not understanding how cleaning can soften bass. But then, that is not what I hear, and I prefer to clean all of my LPs. FWIW, YMMV, etc.
