I'm the poster child for what not to do with sensor cleaning... On my first DSLR (Nikon D200) I inadvertently tripped the shutter closed while sensor swab was in the thick of it. A $300+ shutter repair was the result of my ignorance/stupidity.
I'm now way more attentive and actually follow instructions. Have cleaned all of my DSLR's over the past 8 years with no problems since above one. I use Visible Dust sensor swabs and solution, also very conscientious about using the Rocket blower as often as possible when doing lens changes.
I also just had a Nikon factory service on a sensor oil spotting issue which has definitely helped with much less time spent in Lightroom cloning out the nasties. When in the thick of it while shooting I change lenses frequently and sometimes in very dusty/windy conditions. Rarely will I try to avoid a lens change but on occasion will think twice if there is a lot of obvious dust in the air. Use my body to block wind, keep camera turned downwards and try to to the switch as rapidly as possible.
