Okay, so I'm looking through my viewfinder to check it's all clear as usual and see a little dust which I always clean hassle free taking the lense off and cleaning from the inside.
No problem - I use my visibledust brush to get 99% of the dust off then when trying to get the last little piece out BOOM.. I see my brush wipe a nice long streak of grease along the viewfinder.
The brush must have brushed against a lubricated part so now my visible dust brush is has a small amount, but enough to smear :-\
Either way, I goofed and am wondering if anyone has done the same thing and if so what is the best way of getting the grease off 1: the brush 2: the inside of the viewfinder inside the camera body as it's a tough angle to work with and obviously I dont want to smear it any more.
It's not the end of the world, but like anyone I like a nice clear viewfinder to work with !
Any advice appreciated.

I think the camera is ruined for good and I could use it for a paper weight. I'll even pay shipping. :)

Maybe some alcohol on a lint free cloth.

No alcohol. It absorbs water too which acts as a lubricant. (I have a link somewhere about this) Any dust particles will etch your viewfinder when you go to brush them away. From everything I've read (because I did the same thing) you have two options:
a) live with it
b) send it in to get cleaned.

In my own experience however, I have a cleaning solution for my sensor which worked nicely for the mirror too. The difference is though that your sensor has a lot of scratch resistance whereas the mirror does not.

Also, when I took mine to a camera store to get the sensor cleaned (I didn't have my cleaning kit with me) they were able to clean my mirror with air. Which makes no sense at all since it was grease...

edit: trying to find a reference to the whole "water acts as a lubricant thing"
edit2: I thought I heard it on the "This Week in Photography" podcast (41 I believe) but I couldn't find the reference in the show notes.

Thanks, and appreciated.
This is neither the sensor or the mirror, it's the part on the inside of the viewfinder so basically if you take your lense off, it's tucked up in and looks like a small square of clear glass / plastic.
I've never had any problems before and am gutted I got grease on it !!
I have a compressed air blower. Thanks for the heads up about the alcoholic swabs - I was going to try them but I wont now.
It doesnt affect the photo's any as it's just in the viewfinder. The sensor and mirror are just fine.
I'll check the visibledust website, maybe they'll have something on their site for it.
Thanks both for your replies !

You could try going to an apple store and picking up some iClear. It's a liquid formula for screens and electronics that doesn't conduct electricity.

edit: I'm not exactly sure if it's what you need.

I made this same mistake while in the middle of a vacation in british columbia... Note to world: Don't ever, ever use a brush on the inside of the camera.

Maybe you'll have luck finding something online. I visited 4 camera shops in vancouver and the advice from all of them was the same - send it to canon. Which I did, and they cleaned it. They also replaced the shutter because they said it was worn (on a 1 yr old 30D at the time btw). While it sucked being w/o the camera for a couple weeks, they didn't charge me for any of the repair work.

That sounds a lot like the Focusing Screen, which you should be able to remove in that model, I know I can take mine out in my 40D... on that you can prob get away with some simple lens cleaner and gently wipe it until you get the grease off.

Dave, you're a star. It is indeed the focusing screen so I youtubed it and found this.
