I have a huge sheet of protective glass on top of wood desk with a computer set up on top of that. Dust has collected between desk top and glass. How can I get the dust out without disassembling and removing all the computer stuff?
This depends on how thick the glass is. If the pane is thick enough, you can lift one end a bit and slide some shims underneath, then repeat on the other side until you have a gap big enough to clean between.
But the glass needs to be really thick for this to work. As an example: I have some glass shelves in my cupboard. These are 80x30 cm and 6 mm thick, and are specified for a maximum allowable weight of 10 kg. A desktop computer with monitor is easily twice that, and the pane of glass is much larger. As a first approach, double the size = half the carrying capacity, so if your desk is 150 x 80, you'd need a glass pane several cm thick to carry your computer. This is unlikely, so you'll have to remove the computer before lifting the glass.
Normally the weight of the computer isn't an issue: the entire area of the glass is supported by the desk. But if you lift the glass, it's supported only by the edges.
Here is what I do,
take a piece of cloth,
take a spoon, the cloth covers the back of the spoon,
insert the back of the spoon as you are cleaning the space between the glass top and the desk.
IN CASE THE AREA OF THE GLASS AND THE DESK IS TOO BIG:
- with the back of the spoon with very long (not big in area) cloth, use the back of the spoon in such a way that it comes off the other end, then slide it gently with the right hand and then with the left hand (in a harmonic motion) until you get the whole under glass top cleansed.
