Wet cleaning is the next step in sensor cleaning and becomes necessary when bits, such as pollen, are stuck on the sensor surface, that dry-
With the right tools and the right instruction there’s no need to be frightened of wet-
Yes, you need to take care and to make sure every other cleaning step has been carried out, before attempting wet-
By always exposing test images at each cleaning step, you will quickly learn whether the spots are loose particles, stuck bits or smears.
I recommend using Microfibre Swabs ahead of anything else. Reading the right side column, will help you understand why I recommend and use microfibre swabs and cloths in the workshop.
So how do you use the swab?
With the mirror up and shutter open in Sensor Cleaning Mode (refer to your camera instruction manual), you gain access to the sensor surface. To be totally correct, it is not actually the sensor itself that is cleaned, but rather the filter which covers it. But I will refer to it as the sensor.
The surface may be cleaned by wiping from side to side or from top to bottom. Normally side to side is the easiest, but on some cameras there’s more room to wipe from top to bottom.
You will find more recommendations in the guides supplied with the cleaning kits, and sometimes in the camera user manual.
Swab size vs sensor size:
Regardless of size all sensors can be cleaned with the 17mm Standard size swab. On larger sensors you simply wipe two or more times to cover the entire area.
However, if yours is a full frame camera (24mmx36mm) you would probably choose the 24mm swab since it covers the entire area in one sweep.
After much testing different types I settled on DUST-
It is fast evaporating, non-
Small bottles have been produced, especially for us, by Dust-
Some particles and smears require a slower acting, more penetrating liquid, in order to dissolve sticky matter.
To get what we wanted in the end meant mixing our own, and PRO-
Use the liquids is explained in the kit guides, but it is basically straight forward.
After removing a new swab from the foil packaging, you apply a few drops of Ultra-
We made a short movie showing how it is done.

The criteria for any optical cleaning tool is that it must be SAFE, contaminant free and effective. We tested all methods on that basis.
Tissue wrapped spatulas were low cost and did work, but there was too much handling and the risk of contamination high.
Cloth or sponge type swabs would not fully remove particles, but merely wipe the bits out to the side of the sensor, without removing them.
And the winner …
Having good experience with MicroFibre cloths we decided to make and test a microfibre hooded swab.
By using optical quality material, and, by having a dry swab, we could apply liquid of our choice and volume.
The result is the swabs we use today -
SafeWipe swabs are made using finely woven microfibre cloth. They are individually wrapped, easy to manoeuvre, and made in sizes for use with all sensors.
Since we introduced our swabs several other types, with various types of swab material, have come onto the market. They are all good, however, microfibres are, in my opinion, superior.
Using a new ultra clean swab and applying the fluid best suited for the job, means you get the best option for a good result.
