Timbuktu87 :
what do you guys use to clean the interior if your desktops? I have lots of dust inside and not sure how to clean it, use tissue?
Compressed air is well and good, but if you want the good stuff, do you have anyone nearby with some tools?
My father has a proper air compressor and those are beast for getting dust and stuff out. The one thing you may wish to do is hold the fans in place when using it though - but keep in mind not to make the blast too strong or it'll move the fans irregardless of your efforts!
But yea, they're really helpful. It's also nice because then you're blowing dust and dirt out into a place that's already dusty and dirty, over clean living space where you might be encouraged if you have dustbuster.
