No, the O-ICK1 is good for multiple, multiple applications.

The correct way to use it is simply touch (don't push or rub) the sensor, then quick wipe on the release paper. Repeat, repeat, repeat, repeat, repeat, and if you space your touches correctly, you're done!.

but it's too expensive and I have only 20.

Also I don't want to spend money for 50dollar of only 1use of cleaner

I just cleaned my K-7 for the first time with a rocket blower. it worked very well and got rid on dozens of dust spots.....

You've had some good advice here rlatjsrud, don't cheap-out on the solution or you'll be out much more than 20 bucks...

Hi

Firstly please realise the sensor, while it is a delicate piece of engineering, is more robust than you would think. The fear of doing damage to it only makes your hands shaky, so take a deep breath, relax and get to work in the knowledge that it actually takes some doing and some extraordinary stupidity to ruin the little blighter.

I am not a great fan of the famous blower as, in my experience, the blower will not always shift the crap and if it does the dirt will just be blown in to a new location inside the chamber. Turbulence created by the mirror slap and pump action from expending tele lens tubes will than make it re-appear back on to the sensor one day.

I have been using the PENTAX O-ICK1 "orange lolly" (as I like to call it) for many years with nothing but total success. And I use it when ever I discover dirt on the sensor. I check regularly and the reason simply is this; You never know what the particle that is stuck on your sensor actually consist of. It could be anything, from a piece of Salami, (just kidding) a sweaty piece of skin flake a particle of a ferrous nature (which could rust with humidity) to just an ordinary bit of dust. The point is, since you do not know what it is, it is better to remove it quickly before it has a chance to "weld" itself to the sensor surface over time in which case a wet cleaning method will be the only way to get rid of it. For the last 4 years I never had to do this. So please, in my opinion, don't ignore or live with it and let the dust linger. I go so far to say that every wet clean is the result of an unknown speck of crap that got stuck to the sensor because it was given time and therefore a chance to "ferment" through humidity and condensation.

When using the "orange lolly" follow this way:
Make sure the surface of the lolly which will make contact with the sensor is clean by dabbing the supplied paper. To make sure you don't dab the same spot of paper again next time, overlay a grid of little squares roughly the size of the lolly head by scoring the paper lightly with a Stanly knife. (You can't use a pen for this) and then tick off the used one with anything sharp. This way you always know which part of the paper was used and you don't wast paper either.

When applying the lolly press down firmly with A LOT OF GENTLE FEELING (I think you know what I mean). You will feel a very slight vibration and a little hum coming through the shaft of the stick. This is normal and I think it comes from the SR system.

Now when it comes to lift the lolly off, slowly tilt the shaft to one side and then lift off, don't lift the thing off by moving it up straight as it will make it harder to disconnect. Do not drag the lolly head across the sensor surface either. Now dab the next unused paper square and repeat the process until you feel happy all trouble spots of the sensor are covered. Check for dust and if necessary repeat the process. (Sometimes you need to go over several times).

That's it you are done. There is really nothing to it. (Oh, one more thing, shine a bright desk lamp into the opening so you can see what you are doing.) After you have done this several times you will wonder why you were so scared of it before.

Greetings

Blowers will do more damage that good.

Let me explain. Air has moisture in it. Air compressors have have water drain valves on them.

Now to prove it. That's where I"m going a little bit of trouble. I dont have any clue on how to show you.

This Is how you do it.
Take a VERY clean piece of glass ( test type glass for microscopes) take you blower and blow the glass a like its the sensor in your camera. Place glass in microscope and look at all the water spots. When the water dry's you will have water stains.

How did I learn this.

I bought a rocket blower the sensor on my camera was clean But I blew the sensor anyways then these spots appear and they weren't leaving.

Then I take both my cameras to the local camera clinic. I only blew out one camera with the rocket. With out saying a word about a blower the man behind the counter tells me what I did.

The shop has micro scope hooked up to a monitor.

Agreed, get it professionally cleaned every no and then if you're after serious clean.

I think his point was that he could have done it himself at home with the same tools and that a rocket blower is counterproductive.

Sorry, utter nonsense. They only use the same tools and method available to you. It amuses me to no end every time I read these scaremongering comments by people who profit enormously by selling you cheap cleaning implements at 2000% inflated prices.

They have you believe the sensor is as fragile as a soap bubble, well it is not.

Just use your common sense when you approach this cleaning task, respect the fine piece of engineering the sensor is, follow the instructions and you will be fine. I started to clean my cameras sensors starting with the K-10D right through to the K-5, must have done this a 100 times and more and never, repeat never, hat anything go wrong!

If you use the right tools it is actually not easy to kill the sensor.

There is only one caveat: If you have two left hands, full of thumbs and have the shakes, then perhaps it would be better to let someone else do the job.

After my experience of getting my camera sensor "professionally cleaned", I'll never let a camera shop near my sensor ever again. Giving your camera over to someone else to clean is a classic case of YMMV.

YMMV
You are right ! Unless the people employed by camera shops are recruited from outer space where the quality of people and skills may be superior I see no reason to have someone else do it for me.

If you can eat with a knife and fork without poking out your eyes you can do a sensor clean. It's dead easy

Pardon my ignorance, what is YMMV ?

"Your Mileage May Vary"

Derives from the caveat given with estimated fuel mileage for new cars in the US. Originally CYA lawyer-talk, it is used on the Internet as an indication that individual results may vary.

sorry to hear that...
my K-x needed cleaning this spring, there was a lot of pollen stuck on it..I was lucky coz I found a guy doing wet cleaning for 12 euro in one hour...he is an older person and experienced camera tech living in the city I work in
major camera e-shop offers the same service for 27 euro...pure robbery and you even have to get to the capital to give them the camera
but I`ll hopefully get the Pentax O-ICK1 set to carry everywhere
