Static is one thing that the vacuum cleaner sorts right out, due to the water.
I'd never noticed the brush making a difference. There is an argument about technique where you move the brush towards the centre post on the deck until it touches it which is supposed to make it pick up the remaining debris due to earthing the brush. There's a video out there somewhere.
For static a lot of people like the anti-static guns. There's also the spin clean which is a manual liquid based cleaner.
I like to think that they are good for destatifying (what's the right word?) new records.
