Did I damage my cartridge?

I had purchased a zerodust stylus cleaner. The first few times of use went ok. Now I seem to have a fuzz added that is bothering the hell out of me. I can only assume that maybe I applied too much pressure during a cleaning and could have possibly damaged something. I have tried to clean again and tried many different LP's with the same results. There is a fuzz to the music. My GOD what did I do???
Any Ideas?
