K-3 has Dust Alert but K-30 doesn't. It's a great feature.
Originally posted by Adam The general procedure is: in-camera SR -> blower -> static brush -> swabbing -> professional cleaning.
The idea with the brushes is that you give them an electrostatic charge with compressed air first, so that they pick up the dust with minimal touching of the sensor. Of course you need high quality brushes like these:

I use one of the equivalent sticky wands:
DSLR Camera Sensor Cleaning | Dust-Aid (Nothing to do with Bob Geldof.
) Their starter kit includes swabs for wet cleaning too.
I'd echo the warnings about keeping wet cleaning as a last resort. I scratched a sensor once, even though I was really trying to be careful.
One more tip. A loupe with LED lights really helps you see what you are doing. I've got a cheap one, and it's handy, but the best ones are those that have a cutout in the side to accommodate the brush or swab, like the one in this kit:
