There are two points of view here:
1) If you have a few small dust spots, be tolerant and simply use your 'spot removal' tool in your editor.
2) If you've sneezed intot he mirror box, (or changed a lens whilst on a beach in a storm) a wet clean will be required.
For (1) an 'Arctic Butterfly' is best. Almost non-contact, it removes dust using static electricity. But not cheap to buy.
For (2) and only for extreme cases, unless you are very confident, get it done professionally. It's all too easy to scratch the cover glass on a sensor, which will require eternal work in your editor thereafter.
I would avoid anything which requires 'wiping' the sensor. There are plenty of enticing products out there, but they offer no guarantees, either to remove the dust or not to scratch the sensor.
