As title, iv got a manual air squezzy thing to blow air onto the cameras sensor, but 2 dots are just NOT moving, very annoying, I dare not touch it as it would probably ruin it, any ideas on how i can shift those last 2 specs?
 
Just did a quick search of the forum for 'clean' & 'sensor' and found these results:

I've probably broken the forum record for most links in a post but I remembered that cleaning sensors were a bit of a worry for quite a few people recently so I knew there would be plenty to look at for hints and tips.
 
Be careful a lot of sites don't recomend you try and clean the sensor as there a good chance of you trashing your camera. It may be worth spending a few quid to get the pros to do it.
 
It's not easy to "trash" the sensor if you use the copperhill method, I've been using it since i bought my first dslr the 300D and the same swipe has met the sensors fof many dslrs since then and not a single problem at all. Follow the guide and all will be 100% fine and do make sur eyou use pecpads and eclipse fluid, not isopropyl alcohol like some twits on another board or 2!!!

You need to apply minor pressure when swiping the sensor though to get rid of stubborn dust, do not be afraid but don't apply heavy pressure either, just enough so the swipes head bends a small amount and then swipe from edge to edge in a U-turn style way as described in the copperhil guide.

Blowers/dusters/brushes etc are pretty useless for anything but minor/soft dust on the sensor, they just move the dust around, not remove it completely so the same dust settles again afterwards and holding the lens chamber upside down to let dust fall to the ground? dust floats in *** air...gravity has little affect on it... :D
 
Looks like the copperhill stuff is US only now, anyone know where I can it delivered to UK?
 
*they* sell cameras, OcUK sell cameras. Competitor.

They wouldn't clean it anyway. Canon would, at a hefty fee - most likely taking their merry time about it, and in no way guaranteed to come back any better.

DIY.
 
I wouldn't send it off to Canon in all honesty. I've heard some pretty poor things about their sensor cleaning ability. Cameras seem to come back with more dust on than they went with.

I use the copperhill SensorSwipe, Pec Pads & Eclipse cleaning fluid. You'd have to be pretty brutal/clumsy to wreck the sensor by cleaning it this way.
 
Here's one trick I use for astronomical CCD cameras - which are prone to collect dust as the optical system is often 'open' all the way to the chip face (using Newt reflectors anyway). Buy a small puffer brush and unscrew the brush from the rubber squeezy bit. Attach a length of silicone tube to the brush and insert the other end in your vacuum cleaner hose (use a wadded duster to get some sort of seal). Now the thing sucks instead of blows, the brush will dislodge the dust and it'll get sucked into the brush head, effectively removing it from the camera instead of just moving it around. Doesn't work for sticky stuff of course, but your best protection there is not to get it on in the first place! Astro cameras setup near trees have a problem with airborn tree-sap droplets - a real problem this time of year - and the resinous specks are a right pain to remove. Only recourse there is a solvent approach.
 
it took me plenty of attempts the first time I cleaned my 20d using the copperhill method ,and there was still a few very small specs left , now I`m getting pretty good at it and last time I cleaned it I had zero specs showing at f22, even after i done an auto levels in CS2 :)
 
Is the same method recommended for cleaning the mirrors?

As my 350D has speck or 2 when looking through the viewfinder but they do not appear on photos at all. So don't appear to be on the sensor.
 
Your all pussies, Get the job done properly.. :p

My 350D has the same - I'd be interested in the answer too.
 
the mirror doesnt affect the light the sensor captures, nor does the focus pane

when you take a shot the mirror flips up as the shutter opens

so any dust on the mirror or focus panel will not affect your photos :)

Yes but it winds me up when I'm taking pictures & see it the view finder :D

I clean my mirror by the same method, only if it has stubborn dust on it, but i`m very very careful,usually i just used a rocket blower as the mirror is pretty delicate as its a moving part
the focus pane is awkward to reach though so i dont normally bother with it
