Hello guys 
my question is about cleaning graphic cards, I know the basics and I know how to clean my heatsinks and fans very well but I am looking for a safe-if-you-know-how way to clean the surface dust that you can see on graphic cards after some time
Is there such thing ?
I can provide pictures later if I am not clear about what I am reffering to
