Overview

• Phone swabs consistently detect hundreds of bacterial and viral species, underscoring contamination risks from everyday handling.
• Apple and Samsung warn that bleach, hydrogen peroxide, vinegar, aerosol sprays, window cleaners and alcohol concentrations above 70% can corrode materials and strip protective layers.
• Users should never spray cleaning solutions directly onto devices, submerge them in liquids or use paper towels and tissues to prevent moisture intrusion and surface damage.
• Tech experts recommend using 70% isopropyl alcohol wipes, soft microfiber cloths and anti-static brushes made of nylon or natural fibers to clean screens, ports and speaker grills gently.
• A weekly cleaning regimen under normal conditions and more frequent wipe-downs after visits to hospitals, gyms or public transport maintains hygiene without over-wiping.
