What should I clean the inside of my PC with?
Compressed air.
Have you stored your computer with a open case near a construction site? Why is there gravel in your computer? You should at least turn it upside down and let gravity get rid of 90% first.

Is it better to use cans or some sort of device?

Well I use cans cause I don't have a separate machine not to mention if you're negligent you might turn the air compressor too high and cause damage.
I tried not using an air can before and actually took my heat sink out to wash it without realizing that my CPU was still attached to it when I was washing it. Since then I just play it safe and use a can of air.

The fire will get the dust out of all the hard to reach places, and the kerosene will not only clean everything but since it evaporates at a low temperature it will cool your rig and therefore make it better.

Just drink plenty of water and blow on each component individually.
