Cleaning pcb?

[SamyBoy13]

Hi there guys is it safe to clean mobo and gpu pcb as fine particles of dust have set over them and pcb looks grey-ish. I tried compressed air but dust is still there that looks grey. Any ideas?

I just found some isopropyl alcohol wipes. Would they be safe to use as it doesn't say how much isopropyl alcohol is there eg 97% etc in them. Should I assume it's 100%? They make my hands really dry even if I touch them for few seconds.

Okay thank you all guys will try brush first Can it be any brush or does it have to be antistatic free eg natural ?
