2. Use a soft brush: Gently clean the vents by brushing off any visible dust or dirt.
3. Vacuum the vents: Use a vacuum with a narrow nozzle attachment to get rid of any loose debris inside the vents.
4. Use compressed air: Blow compressed air into the vents to remove any deep-set dust or particles.
5. Wipe with a microfiber cloth: Finally, wipe down the vent slats with a microfiber cloth to remove any remaining residue.
