What Do You Need to Clean Dust from a PC?

  • Soft brush: Look for a paintbrush style or something similar, preferably with soft, non-metal hairs. This will be your go-to tool for moderately sweeping away dust from the corners and cracks of your PC components without scraping them.
  • Microfiber cloths: These are the superheroes of cleaning cloths. Microfiber is gentle on surfaces and won’t leave behind fluff or scratches. They’re perfect for spreading down hard surfaces and catching dust the brush released but didn’t remove.
  • Isopropyl alcohol is excellent for cleaning more challenging spots or any sticky remainder. Make sure it’s at least 70% isopropyl for actual cleaning. Always apply it to a cloth or gauze first, never directly onto your PC components.
  • Cotton swabs: These little guys are perfect for detailed cleaning, especially in tight spaces where a cloth’s strength does not reach. Dip them in isopropyl alcohol for an added cleaning boost — just make sure they’re not soaked wet.
  • Handheld vacuum (optional): If you have a vacuum, it can help pull up dust. Just be sure it’s set to a low-force power to avoid damaging any PC parts. An attachment with a soft brush end is especially near here.

Each tool is precise in your cleaning quest, confirming you can tackle dust without needing compressed air.
