Thank you Leica repairing Dust-Aid damage

I just got my M9 back from Solms (two weeks turnaround door to door, including wait for a spare part) The cleaning damage by Dust-Aid meant a new sensor... Thanks to Passport Warranty it did not cost me anything, but I will not be using the system any more.




I used the stamping tool according to the instructions. It did work reasonably well. However, there are "Sellotape" strips to remove the particles from the cleaning stamp. The adhesive adhered to the cleaning pad and thus got transferred to the sensor. The sensor got scratched by the subsequent extensive wet cleaning to get the gunk off again -that stuff really clung to the sensor! -, probably because the adhesive contained one or two hard particles that had just been lifted off the sensor, but got stuck on again by the rests of the cleaning adhesive. Furthermore I got the impression - but have no proof- that one corner of the IR filter had some movement to the sensor itself by the pull of the pad.



I have switched now to the vacuum cleaner by Green Clean and their wet and dry pads and I have the impression that system works as advertised.

Glad to hear Leica fixed the sensor without charge. So far, all my sensor dust issues on my M9 have been cleaned by a rocket blower.

Glad you got it fixed free Jaap, now you have me worried as I also use Dust-Aid too. When you did the wet clean was that also with Dust-Aid swabs out of interest?

Maybe I should have used their fluid fist. But I started off using Eclipse2 and sensor Swabs. Working under the microscope, I found that E2 used in the amounts needed left a white residue so I switched to the DA fluid which dried much cleaner. I got nearly everything off, and finished the last rests with the green-clean wet-and-dry swabs. Only after cleaning did I find the drag marks on the sensor. I blame hard grains reapplied to the sensor by the adhesive, but it might have been the E2 residue (very unlikely, but I cannot be sure)
