Wet-clean your sensor, or just blow it off?

While others speak highly of using a rocket blower to get dust off their sensors, I've had nothing but mixed to bad results with anything but wet cleaning. Here's one recent experience: http://esfotoclix.com/blog1/?p=669 ~~~ eNo http://esfotoclix.com I have found it is always best to blow out the chamber first, then brush with a chamber brush, and blow again before exposing the sensor. A few puffs with the "rocket" and most loose dust will be gone. Agreed there is no escaping wet cleaning for persistent spots and chamber lube spots. The only word of warning is to be sure of the type of sensor. Most CCDs will do fine with a swap and Eclpse fluid. However if you have a tin oxide CMOS sensor DO NOT USE standard Eclipse methanol, use Eclipse E2 fluid. http://www.photosol.com/ -- Regards, Savageduck |

A few puffs with the "rocket" and most loose dust will be gone. How about using some sort of small vacuum cleaner in conjunction with the blower? It seems to me no matter how you blow out the chamber, whether the mirror is up or down, you're likely to be mostly just moving the dust around unless you're using something to draw it out while it's circulating. I don't have any such device in mind, but there must be something out there. |

I don't have any such device in mind, but there must be something out there. There are small brush/vacuum devices, operated on double AA cells small enough with enough draw to pull disturbed dust out of the chamber as you blow with compressed gas. These devices are found in computer stores, and may be ordered on line from TigerDirect and similar. They're sold as keyboard vacuums. Low cost. Not big draw, but enough for this application. |

I don't have any such device in mind, but there must be something out there. Using a chamber brush, by first blowing through the bristles puts a charge on the brush and it picks up most of the loose dust in the chamber. That minimizes dust in the chamber to land onto the low pass filter. Then I expose the sensor & low pass filter and check to see if that will blow clean before resorting to a wet clean. -- Regards, Savageduck |
