How to clean the fan

My laptop is overheating and i can feel the heat through the case and so l eventually came to the conclusion that the fan is not working but because dust is trapped in the machine. And originally, i was planning on taking it to a computer store so they could clean the fan but I'm trying to save a dollar or two by doing it myself.. Does anyone know how to go about doing that, safely? Because i don't want to destroy my laptop. Thanks.

Unplug. Switch off. Let it cool down for tens minutes. If it is really dusty strip it down to Step 12.

If you are not confident to take it apart. Just use your vacuum cleaner on the rear & top vents. Preferably with a small brush attachment (if you have one)

I applied colgate on my CPU while I was cleaning my motherboard with spirit. After that my laptop could not switch on and the fan is not even turning around. What should I do? Can it be reversed
