Dirty sensor begone

I've just wet cleaned my K-7 sensor. No amount of blowing would get this little bugger off. This is the second time I have done it, did it a few years ago on my *istDs.

I'm posting this as it really is easy and I encourage all but the most timid or shakey to do it rather than getting a shop to do it. The cost of the gear for me was about the same as one professional clean, but now I've used it twice I've already saved my self the cost of one clean!

I used a bottle of "Sensor Clean" (tm) and a Visible Dust swab (from pack of 12), and followed the instructions - easy as.

Just do it.

IMO. you can't beat a wet clean!

I've been doing it for years and its worked great(never let me down).
I honestly don't understand why so many companies and people spend so much time and effort trying to clean with alternate methods only to find it either doesn't work or makes things worst in the end tbh.

PS. I use 17mm sensor swabs + solution to clean my mirrors also.

Yes, wet clean works. I use items from Photographic solutions on the K10d/K7.

Pentax has its own sensor cleaning kit, the O-ICK1, it's that good that LEICA is using it in their own factory to clean sensors while assembling them in the body. As it is designed for Pentax sensors, so why using something else?

I used this product in the past though it would not remove a small stain on my sensor. However the biggest problem I had with it was the price and the lack of re-usability. ie. a bottle of Eclipse sensor cleaner can be used for many applications(25 times or more), so all that's needed are more swabs which are relatively cheap.

Having said that, my kit didn't remove a small spot on my sensor. It wasn't dust or debris. but more of a faint blemish that would appear in bright regions of my images. A first wipe reduced it, and a second pass eliminated it.

Yep, I'd say that's the one, though my bottle is white, but a few years old now.

The O-ICK1 kit can be used for a long time, as long as there is one of these sticky papers left. I have mine for about two years now and I still have half of the lot not used, tough I am changing them every time. I am shooting exclusively with primes, thus switching lenses all the time, carefully...

I've used that recently as well. I did have to use two different Visible Dust products to get my K-x sensor clean, though. Some work better on oily gunk and some work better on water-based stains. I don't know what happened on my Spanish trip. I wouldn't even say that the stains in Spain were mainly on the plain.

I have their survival kit. Used it once so far with good results after a very dusty and dirty camping trip. Their stuff looks like it's the least expensive that has good reviews as far as I can tell.

This topic and my ridiculously dirty sensor tempted me to try some testing. Quite by coincidence the visible dust wet cleaning stuff was the only one I could get today. Here are the results. I'd say that visible dust wet cleaning is the clear winner.





Taken before cleaning. Same part of the sensor, but different focus points on the piece of paper (ie I swivelled the tripod around a bit to verify dist spots, and these are crops of the same few 100 pixels in one corner)





This is after using an "arctic butterfly". This splendidly named device is a very fine brush + battery power rotater. You let it do its thing for 30 seconds to build up charge then stroke it over the sensor to remove the goop. The charge + brush theoretically pick up the dust and make the sensor clean. Works, but not 100%.





This is using the visible dust wet cleaning stuff. I'd say we're almost there, and it's better than a dry clean.

According to the manufacturer the butterfly is supposed to get goop, but the liquid cleaner gets water based stains and there's another liquid "smear away" for oil based stuff.

My limited experience was that I needed both the smear and the water based cleaning to get it "perfect."

Same for me but I have to say that since I use the K-7 I never used it anymore. And for the K-x I get sometimes a spot or two easily removable with a small rocket blower. And I of course change lenses all the time.

BTW do you have any reference about Leica using this kit?
