As Colin says, KR is a colourful guy and half the time he says totally contradicts himself across his various postings. He is entertaining to read, but the one things that irks many readers is that he has trouble differentiating between facts and (his) opinion.

Clean sensors is a must. If left unclean, it may eventually ruin all our efforts to get that clear/focus shot.
------------------------
btw, Ken Rockwell's website is an ok source of info. Just like Thom Hogan, DPReview and others.
Perhaps , those who know KR is giving fictional info can post corrections for the benefit of all. -

25th April 2013, 12:13 PMColin SouthernRe: Clean Sensor: How important is it?It's a great theory, but in practice, if the sensor is so badly covered that it's attenuating all the light then under-exposure is the last of your worries. I've had sensors with hundreds of spots - I've had a sensor so bad that Canon had to use a $2,000,000 piece of kit to actually REMOVE the sensor to clean it properly ... and still exposures weren't even slightly affected.Quote:

About the worst thing with sensor spots is that international recording artists use the shots on their websites when the raw shots were only released for initial selections (even though I've subsequently provided fully retouched versions!) ...

After about 10,000 shutter presses on my D800, I had some pretty nasty crud on my sensor. It wasn't dust because the built-in sensor cleaner couldn't take care of it, and my Giottos blower couldn't either.
I don't want to advertise here, but I bought a Copper Hill cleaning system, and it worked like a charm.
I hope I don't have to clean my sensor often, but I'm no longer scared to do it. -

What usually does the trick is identifying the spots with the illuminated loupe - dislodge them with the sensor pen - and then remove them with either the blower or arctic butterfly or sensor stamp.
The other thing is that if one tries for perfection every time them they'll probably be chasing their tail for a long time.
