Wet Cleaning records makes things worse?

Hi guys,

I've been working my way through the record collection I inherited from my Dad - lots of fun and the records are pristine.  I usually only need to dust them with a brush and then lightly wipe them off with a microfibre to get the remnants and this seems to work well for 19 out of 20 records. 

However, when I come across a record that is particularly dusty I'll wipe it down with Pfan-Stat on a microfibre cloth.  It looks clean but when i play it, a little dust ball will build up on the needle rather quickly.  Then i need to clean the needle after each song.  It seems to only happen when I clean with Pfan-Stat.

Am I doing something wrong? Is the Pfan-Stat just loosening the dust and i need to fully remove it some other way? Is there an inexpensive way to deep clean the records even though they 'look' clean?  Would there be a benefit to this?

Thanks!!!
