do record cleaning fluids soften the treble?

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.

Rrm,
I felt that the sound did change and a little softening did occur. One day after playing a record it slipped and I grabbed so it would not hit the floor. I put finger prints all over it so I had to clean it. I had started doing a final rinse after cleaning my records but had not done it to this record because I had cleaned it a while ago. After a cleaning and a rinse I played it again, I found it had better all around sound, better hi's, bass was faster with more impact and the record had much better micro dynamics. I will now reclean the rest as I play them so I can do a final rinse on all records. I clean all record regardless, you can never tell how a record is handled by the manufacturer or dealer

Cleaning new and old lps is a must and a double rinse is the answer for clear noise free playback. What i find very interesting is if you dont include a small amount of a release agent to your rinse water you will leave behind residue.

Dave: Now,now,where then would that leave the others here who favor cleaning more as a matter of routine? Just kidding of course. There's plenty of room in this fascinating pastime for those taking the other road to optimal listening pleasure.
