[Leica] IMG: this is VERY strange (OT)

[Jayanand Govindaraj]

Jim,

I have been cleaning sensors ever since I went digital, over 10 years now,
and its a piece of cake. So get over the mental block, and dive in!

I use either SensorKlear or Eyelead, whichever is available when I need
one. Both are extremely easy to use (apparently, the latter is what Leica
technicians use):

Cheers
Jayanand
