If you were where I live, you would need to clean your rigs daily. My country is the fifth most polluted countries in the world according to WHO (World Health Organization), and dust existence is beyond measure. I clean my rig at least twice a week, and just 6 hours after I clean it, it collects dust. If I leave it for a week, my components become literally unrecognisable with dust covering every inch of them.
It gets frustrating, so don't blame me for getting lazy sometimes
