So you think a cotton ball is better suited to get down in the grooves

I forgot to say that even if the cotton strands don't get down into the
groove maybe they just swirl the fluid around enough to lift the
adhering dirt away, with the help of the glycerin wetting agent.

I'm also intrigued with the idea of playing the record wet. I have an
old but not excessively worn stylus I might try one day.
