Vacuuming the Fan's plastic housing + sieve?

[tom_curitiba]

I am cleaning my laptop from time to time with a vaccum cleaner. I read it can be bad but I am not sure it is the case.
I would like to have your opinion
Here is what I do:
I open the back cover, then take off the thin steel cap from the fan and there I take the dust off from the fan (holding it) and from the sieve with the vaccum cleaner.
I read that vaccum cleaner creates static electricity and it can be bad if done on the electronic components.
But in this case, I only vaccum locally where I can only see plastic parts and no electrical components (the plastic fan and its plastic housing + the sieve which is in metall but connects only to the outside).
Am I doing something wrong? or the fact that I only vaccum there locally on the plastic parts is ok?
Thanks.

I would suggest that vacuum is ok for the outside casing such as keyboard and ports. However, for the inside, its best to buy a can of compressed air and gently use it in short bursts to blow out dust.
