I rarely find it necessary to clean LPs. Usually a dust brush right at the time of play is sufficient.
FWIW I also don't experience a lot in the way of surface noise. The phono equalizer (preamp) can exacerbate surface noise if the preamp is unstable. My preamp employs passive EQ, which helps a preamp be more stable, and even though bandwidth is unaffected, surface noise is obviously reduced.
So its rare that I have to clean an LP.
