Hi All,

Watch out for the CANNED AIR/Dry Air containers,
I warn you do not use them to remove dust from your CCD !

I had some dust on my CCD, and used one specified for cameras,
Lo and behold, one squirt and the CCD looked like it was shot with a shotgun.....

The chemical compound used in the cans tend to freeze up as soon as they leave the nozzle and the ICY bits then stick to the object, especially a S2-CCD :)

The only issue is the ice leaves residue and don`t come off.
The only way to clean the CCD then is the SWAB method. I opted to take the S2 to a service centre who cleaned many CCDs.

I`ll keep that can away from any internals.

Advice: Get the more powerfull hand held, squeeze type blower, the type that looks like a football with a snout.... you know what I mean, and pump the dust away by hand.

You have been warned.
Ben

Hi there

Did the exact same thing back in March of this year... then went straight to Fuji to get the CCD cleaned. I agree - NEVER used canned air to clean your CCD. You are just asking for trouble!

Phew... Phew and PHEW again,

Got my camera back from the 'cleaners' and the damage wasn`t permanent. The guys could luckely clean the CCD satisfactory, $66 later :(

There are still the odd micron spot of dust, PS will have to do its cloning trick if need be. Their reason being the clean room isn`t very clean, eh.. non existent to be exact ;)

Hope no one has to go through the '..wait for the news, cleaning the CCD..' session.

yep, ... i just did it as well ....:mad:
leaves a nasty frozen like pattern on the CCD, ... i did it from quite a distance cause i thought the ice cold from the can couldn't be to good for the CCD but didn't think that PURE AIR (as it says on the can) could leave any residue ...

glad to hear that it goes away with swabs, .. which i'm off to try now ...:D

happy to report that i successfully cleaned my CCD ...

bought some swabs for 85 euro :mad: (now that i've seen them close up, i recommend u make them urself, their not exactly hi-tech equipment)

and some pure ETHANOL from the local pharmacy for 1 euro 59 :p

wasted 2 swabs to get the streaks completely away

now everything is CLEEEAAAN and i can kiss my healing brush in photoshop goodbye ...:D
