Do you clean your records before play, after play, or once (and then never again)?

I've thrown out my carbon fiber brushes. At best it simply pushes crap around the records (I believe anything a carbon brush would remove would not affect the play) and at worst, it's creating a static charge that attracts more crap to the record (yes, I know there are "anti-static" brushes, but I'm suspect).

I clean my stylus (primarily) with a Magic Eraser, but every now and then I'll dip it into some Fun-Tak (per the recommendation of the Sound Smith).

@ptss,

I think Last Record Preservative is the next step of awesomeness after an ultrasonic cleaning. 

I provided a fair bit of commentary (including a Q&A w/ Walter Davies @ LAST) on LAST Record Preservative in this thread...
