then you weren't using it right. only oily dirt sticks enough to require wet swabbing. i won't use a sensor pen because dry rubbing has a much higher probability of scratching than wet and if i am going to apply pressure, i want a completely fresh surface every time i go to clean. you won't know until it is too late whether the pen surface is grit free or not.
Herb....
Lets see (this wasn't the arctic brush it was visible dust brush btw). I looked at the sensor, it looked fine except for some stubborn dust, I blew the brush with canned air, and I brushed as directed, and the dust just got pushed around. I guess I must be stupid
The sensorKlear uses a fine dry carbon based lubricating and cleaning compound and soft surface. You don't press very hard to clean with it. It is just as likely to scratch the surface as a wet cleaning method if there is sharp debris on the sensor.
I always wipe the pen surface on fresh lens cleaning paper before using to assure there isn't any debris on the pen.
A brush bristle is "dry", not lubricated, and much harder than the lens pen. It is also capable of dragging along a sharp spec.

Absolutely not true. Just do a search here on FM. There have been several reports from experienced users who cracked their sensors, and they weren't really bearing down.
It is evidently safe as long as you are constantly, 100% vigilant about using the lightest pressure possible, but mistakes happen.
You will also find, if you read past threads, that the coating on some 5D HPF's was not done right at the factory. Not enough heat, evidently. It can thus be removed with certain cleaners. I believe (don't quote me) that E2 fluid is regarded as safe, even for these "defective" filters, but you probably want to be even gentler if you're cleaning a 5D.
a sensor pen requires pressure to work. a brush isn't supposed to. Visible Dust demonstrates their cleaning with fine silica dust on purpose. try that with a sensor pen.

Well I don't see how you use a brush without applying pressure -it wouldn't do anything. And with the sensorklear pen I just pass it lightly over the surface, I don't apply much pressure at all.

I use a rocket blower to begin with, then the Arctic Butterfly and then do a wet clean with Sensor Clean and the swabs if required. Been using Visible Dust brushes for years and the AB just takes the sensor brush to the next level. Works very well for me. Oh and I also have the Sensor Loupe which I find very useful as I can actually see the dust or smears and target the cleaning rather than clean, test, clean, test, until it is right.
Same here, normally a rocket blower followed by the Arctic Butterfly works fine 90% of the time. For tough stuck on dust, I use Eclipse and Sensor Swabs.
that is why the brush is prepared for cleaning in the specific way it is, to build up a static charge that attracts dust. the sensor pen can't clean without pressure while the brush can.

This is ridiculous, I am tired of this pointless back and forth. I don't care how you prepare the brush, you still BRUSH with it, which means pressure, and more than you think. I doubt any more pressure is applied with the pen, and it is a softer, lubricated surface.
you don't get it. you do NOT brush with it. i have use sensor pens in emergencies. they are my last resort field sensor cleaner because you have no choice but to rub with it.

Here are the instructions for using the arctic butterfly:
Rotate and gently rest bristles on far edge of sensor.
Do not apply too much pressure.
Lightly draw the bristles over the width of sensor.
and
Take the Arctic Butterfly® - 724 and gently brush across your sensor ONCE. Do not spin the brush while on sensor! Keep your fingers away from the power button on the device while cleaning the sensor to prevent accidental spinning.
If that isn't brushing I don't know what you call it. Even they call it brushing for goodness sake.
if you can't see how much additional force is required to have the sensor pen, you'll never get it. bristle force even at its highest is far less than the sensor pen. you brush a lens first before you rub with a lens pen. a sensor is the same except it's more sensitive.

Absolutely not true? If you're going to make such a bold statement, please post some references with photos of these cracked sensors as well as reports from the experienced users to back it up. I have seen people scratch the glass filter by using "experimental" cleaning methods, or by using bad technique, but I have not seen a cracked one.
I have a sensor that I pulled out of a digital SLR, and the glass on it is 2.5mm thick. If you were to crack this piece of glass, that amount of force would likely blow the sensor through the back of the camera. It would literally take a hammer and chisel to crack the glass filter.

Sorry, I think your the one not getting it Herb. I don't put lots of pressure with my sensorklear, nor do I with brushes. But brushes are springy and place lots of force on a small area resulting in lots of pressure. Catch a particle on a brush and it is just as likely to scratch a surface as with the lens pen moved across the sensor lightly. In your case you are using the lens pens as a last resort on hard to remove particles the brush couldn't, by your own admission, and hence are placing more pressure on it than you would normally - not the normal pressure you would place on the sensorklear to remove typical dust.
the sensor pen is also springy but with a much stiffer spring. that means that pressure on the sensor pen is much harder to control accurately than a brush.
i never use sensor pens to remove dust. they are for removing oily smears after the dust is gone when i am unable to use a wet cleaning. greater than 90% of the spots on my sensor are grease-free dust.
as i said before, Visible Dust demonstrates their brushes with a mixture of gunk that includes silica dust. the brush doesn't even have to touch the sensor to work. try that with a sensor pen.
The sensor pen is perfect.
Two XT's, XTi, 1D, 1DIIN, all cleaned perfectly with the pen for me.
I just pitch the pen after a dozen uses.
I have started using the Large rocket blower before and after the pen and it helps.
Blower on it's own though is a joke. Brushing alone, only slightly better.
that means you didn't use the brush right or you got greasy dirt and not dust on the sensor. that's the kind that Canon cameras throw off internally. blower first, brush next, and then sensor pen or wet clean after all dust is gone. the sensor pen or wet cleaning is absolutely required for anything other than loose dust.
