can you help to get rid of this spot on my sensor?

Hi

I got a situation

I used the smear away to clean my sensor

i used this kit http://www.visibledust​.com/products3.php?pid​=414

i follow the instructions on the homepage and i watched the movie

well the fist time i used the kit , during the cleaning the swab with smear away lost a small piece of the circular cloth swab on the right side of the sensor

today i tried to clean again and get rid of the small piece of white swab , it's on the right side of the picture and it's very small

i'm sure it's a small piece of swab, i did notice when the swab lost it , and i checked with the loupe


today i used some swabs with smear away and i cleaned the sensor moving the swab from the left(including the small piece of swab cloth) to the right

but nothing i was not able to get rid of it

what could i do ?

i would appreciate it a lot

thanks

Often when you are doing a cleaning you knock small particles loose inside the mirror box that end up settling onto the sensor. A puff of air from a Rocket Blower will usually do the trick removing them, since they aren't adhered. But sometimes you just have to re-clean the sensor.

If you have gotten a fiber stuck on the edge and cannot get it out, I am at a loss other than possibly using a very fine-tipped tweezer and extract it. However, you would have to have very steady hands, because this would be more difficult than even playing the old "Operation" game.

Constantly wiping down the sensor cover trying to get this could possibly cause more issues later. At this point, perhaps sending it in for a cleaning might be the better choice?

It looks like that is some lubricant from somewhere inside the camera. I would suggest that you get a "wet" cleaning kit and instructions from Copperhill.

If it is a particle, then Dust-Aid should attach to it and lift it off. If grease from the camera chamber then wet clean with Eclipse(2) should do the trick.

My Dust-Aid supplier recommends a dry clean with D-A followed by a wet clean Eclipse.

the small black dot on the middle right side of the image

it's not grease

i used visible dust + smear away is the same of Copperhill


it's a small piece white of cloth

I was looking at several blobs around the whole image. Are you referring to the black dot at the center of the right edge of the image? If that's a piece of cloth, what I would use is a very thin and finely sharpened wooden rod (the type that might hold a cotton bud) and use it to retrieve the piece of cloth.

yes
i added a photo with a red arrow to let you get which is the piece of microfibre

but it's stuck -> http://masters.galleri​es.dpreview.com.s3.ama​zonaws.com …bZAbQ3RdJ6IK57a​EAdBaQQ%3d

There is also a big mark on the lower left.

Have you tried using a corner swab to remove the dot on the right.

I must be the only one scared to death of cleaning my own sensor...

(other than using a rocket blower)

If it wont unattach leave it...its no big deal...people only notice these things when they set narrow apertures and shoot against a white background!!! Check your next pictures taken normally and I bet you will find it hard to notice...I actually have large chunks of dust etc on my 5dMk2sensor from using the 100-400 dust pump but most disappear in shots that have lots of different colors and textures. Sky areas at narrow apertures are the only places I really notice this and if I do I clone it out...Its a lot quicker and easier than cleaning a sensor let me tell you...

A suggestion I got from a photography shop that does cleaning with regards to stuck dust was to use those "Q tips" (-> this stuff http://de.wikipedia.or​g/wiki/Wattest%C3%A4bc​hen ) or how you call them that you can get.

(Plastic stick with some cotton at the end) - make sure it's pure cotton any nothing "strange" on it, put some cleaning fluid (in my case Isopropanol) onto it, place on the dust and gently turn.

-> I did that very successfully on the old 400D which has a lot of stuck dust that didn't want to come off with a regular wet clean.

After applying this "spot cleaning" do a regular clean to get rid of any excess cleaning fluid.
That might help here if you have something that's stuck.

mantra,

I'm not quite understanding your predicament. If it is a piece of cloth fibre from the swab, it should not be stuck onto the sensor's surface unless you have a great deal of lubricant on it as well. You should be able to move it as Skip has suggested with a cotton swab, micro-fibre cloth or brush. If you can clearly see it, then you should be able to gently nudge it and even pick it right up.

The only other possibility is that it may be stuck under or to the framework/rim that surrounds the filter and if that is the case, then you will need to pry it out with tweezers of some kind. But this will require 100% precision to avoid marring the sensor. I would suggest using a brush to pry one end upwards and off of the sensor, then grab it with tweezers. If you are not comfortable or confident doing this, then by all means send it in to Canon to handle. But looking at your test shot again, the line on the right side of the sensor does not go far enough to be caught by the rim, so try the other suggestions first to nudge it loose.
