It's not just the vacuum - the crud gets sucked out once it's been loosened with the surfactant solution and then subsequently removed along with the rinse.

Oh, okay! I like that!

Follow Scott's advice, microscopically examine the intertrack grooves for physical damage.
There is always the option (discussed before) of using an ultrasonic cleaner with the above liquids i.e. distilled water, some alcohol for drying and a surfactant.

I like to use a fine nozzle on an air compressor with a low flow rate as well.
