Power or powder? If when rubbing the ceiling material you see stuff coming out, I would guess the foam backing is failing. Meaning, you best choice is likely a complete tear off and replace.
Oops, sorry...yes, I meant "powder". But it doesn't really seem like the foam backing is failing as it's still very solid...it's more like they tried to sprinkle on some kind of agent to clean it with and then didn't vacuum it out or something.
Slightly different topic (since you mentioned it), the wife would like to take it off and do something different but that seems like a HUGE job...I have no idea what's under it or what I would replace it with...
