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

Map- check out Rushton's thread on DIY US if you haven't-the price of entry isn't crazy, and you can arguably get better results, but it isn't about convenience. And in my estimation, you still need some sort of vacuum machine, to take advantage of different kinds of cleaning, which work synergistically.  

I also clean every new or used record before I play it the first time on my KL Audio and put it in a new sleeve with the date that I cleaned it. The next time I play the record I generally don't clean it again before or after, I probably should do it more often since it is so easy. I wish I could say I clean the stylus each time but I often don't unless I see junk on it.

I always run the stylus through a stylus brush before playing.  

I'm doing the same as Pops…. 16.5, right down to the Magic Eraser, Onzow, and dry brush. I use Audio Intelligent fluids. When lazy or the LP is pretty nice, I use the 1 step # 6. Sometimes I do the 2 step process, with # 15, and distilled water. When I use the #15, I use a designated VPI wand to vacuum the #15. Talk about coincidence, it was Basis that ruined digital for me. I could never go back. I play my Cd's in the car (-: 

Mapman, Okki Nokki machine is only $500, with Audio Intelligent three step fluids it gives excellent results.
I clean every 10-15 plays without thinking about it. Stylus is cleaned before playing each side. It’s annoying but there is no way around it.
Yes, some old records require multiple cleanings with prolonged soaking. New records are dirty as hell too.
