Hints from Heleouis says you a hair dryer blower to clean silk flowers (I don't have any but I'll read anything), Could that work?

hmm, many of the new hair dryers have the ION stuff- I don't know if that would be OK or not..
but an old one should be ok ..
I would start with a low setting first to see how it goes..

with computer off and unplugged ...

A couple places I read that it's best to keep the fans from spinning when you blow air inside the case.
I didn't know that and mine were going like crazy...

If your computer is real dusty unplug everything and take it outside.. on a dry day .. I should have done this too, I made a big dust cloud in the room...

Me Too! Some how we went to vaccums which is OK. Vaccums have issues as well.
Now I have a lot of ideas and I will proceed with caution.
When my son was three, he wanted to help me vaccum. The attachnent was on so I left it,
as he wasn't big enough to push the entire vacuum around. I went in the kitchen for no longer than 3 or 4 minutes. When I returned, I got a big surprise. He was sucking out all the water in the toilet bowl.
AHHHHHHHHHHHHGGGGGGGGGGGGG. D bug7
