We have been using a Christie 2K projector for 6 years, and the recflection
bowl accumulates more and more dust, the air polution in Beijing makes the
situation worse. I want to clean the bowl, although I was told that even
the most careful cleaning damages the bowl more or less, I think the dusts
block more light being reflecting to the screen. Does anyone ever do the
cleaning? Should use alcohol or pure water for cleaning? Thanks.
