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

I clean every record I buy (used or new) before first play. I clean the stylus before every play. I should probably clean the records more often, but mostly it is just one time. 

I use a Hunt brush before playing a record ..removes dust, but not peanut butter.   ....for that I use my Nitty Gritty, but it is usually not used much.

Once.
But I have a backlog of unwashed LPs, and if I want to hear one of those, I will play it regardless, if I can see no visual evidence of deposits on the surface.  

I wash new and used records  on a VPI 16.5 one time and one time only.  I give a record a quick sweep with a Hunt brush before play and clean the stylus with a brush, sometime ME and onzo zero dust after each side.

I seriously dislike cleaning records!  But it is my only form of playback so I have no choice.  My first Basis table ruined digital for me.  

I clean records thoroughly once then just use carbon fiver brush to remove dust after that normally.

I clean records manually which is a chore. If I had a nice automatic ultrasonic cleaner I would probably use it more often. Those things are a significant investment.
