Ok, so those who know me know that I am not really much of a duster. In act, I dust the bare minimum and go with "if I can't see it, it is not going to bother me".
Can't do that here.
The country is so dry and dusty that if you leave your windows open (and we generally do, especially now that even if we wanted to use the air conditioner we can't because the compressor needs to be replaced) everything gets covered with this film of very fine dust.
And it builds up FAST.
I have had the piano for almost 2 weeks now. I used it earlier this week. Last night I noticed a heavy layer of dust on the bench that looked like a film of flour over the whole thing.
