–>We’ve talked about dirty sensors before- how to identify, preventative measures, and a few tips for cleaning. Since it’s so important and such a big concern, we thought it was worth mentioning again and adding to what we’ve already shared. This time, we have Bill Tomlinson, Manager at KEH’s Camera Repair Center, offering up his advice on the matter…
Dust and dirt are one of photographic equipments worst enemies. It has a tendency to get into places you would think impossible. When it settles on your lenses or sensor, it may show up as a dark spot or smudge on your images.
I have found many articles on the internet, that in my opinion, are detrimental to your equipment and I would not suggest following along with those tips. I have found articles that range from using a dry tissue, to believe it or not, using a pencil eraser. One of my biggest concerns with some of these suggestions is that not only can they damage your equipment and lead to costly repairs, but they could also cause your manufacture warranty on your equipment to be voided because of improper cleaning. I highly suggest you read your owners manual and follow the manufacturers suggestion on cleaning sensors over and above any hints you get from the internet. When in doubt, always defer to the manufacturer of your equipment!
If you do need to do a sensor clean yourself, first try the cameras sensor cleaning function (if it has it, which almost all newer digital cameras do). Do not use the bulb setting because the sensor is electrically charged in this setting and can attract more dust. I have seen many repairs come in our repair center where the shutter closed on the swab requiring a new shutter to be installed. First step in trying to solve this problem is to blow the equipment off by using a hand blower bulb, compressed air, or specialized compressed CO2 products. Many canned air products are liquid based and should not be used for the cleaning of dust and dirt from your equipment, so be sure to check your air first. The keyword in trying this done correctly is GENTLE, so gently try to blow the dirt and dust off of your equipment. If stubborn specks or spots will not blow off, there are several statically charged brushes available for purchase. This requires touching the sensor and using gentle swipes to dislodge the specks. If specks or smudges are still present, the use of a liquid cleaner with a sensor swab can be used. This requires a swab the size of your sensor. Move/sweep the swab gently from one side to the other of the sensor without lifting the swab off of the sensor.
If these hints for cleaning dust and dirt from your equipment do not work for you, or if doing it yourself is out of your comfort zone, then visit us here at KEH’s Camera Repair Center, and we will be glad to professionally clean it for a nominal charge.
