Understanding Disinfection vs. Cleaning
Before diving into specific methods, it's crucial to understand the difference between cleaning and disinfecting—terms often used interchangeably but with distinct meanings.
"Cleaning physically removes germs, dirt, and impurities from surfaces using soap and water," explains Dr. Elizabeth Scott, Professor of Microbiology at Simmons University and Co-Director of the Center for Hygiene and Health. "Disinfecting, on the other hand, actually kills germs on surfaces using chemicals. For optimal protection, cleaning should always precede disinfection."
With this fundamental understanding, let's explore how to safely disinfect various categories of personal items you interact with daily.
Safe Disinfection Methods for Electronics (Smartphones, Tablets, and Laptops)
The Contamination Reality
Your smartphone likely harbors more bacteria than a toilet seat—up to 10 times more according to some studies. Considering that the average person touches their phone 2,617 times daily (according to research firm Dscout), proper disinfection becomes non-negotiable.
Safe Disinfection Methods
1. Alcohol-Based Wipes (70% isopropyl alcohol)
- Power down your device
- Gently wipe non-porous surfaces
- Avoid ports and openings
- Allow to air dry completely before using
2. UV Sanitizers
- Place device in a UV sanitizer box
- Follow manufacturer instructions for timing (typically 3-10 minutes)
- Ensure all surfaces receive UV exposure
3. Hydrogen Peroxide Wipes
- Use only electronics-safe wipes
- Wipe gently without saturating surfaces
- Pay special attention to button areas and screen edges
What to Avoid:
- Bleach-based products (can damage screens and coatings)
- Aerosol sprays (can penetrate openings)
- Abrasive cloths (can scratch screens)
- Excessive moisture (can damage internal components)
Dr. Charles Gerba, Professor of Microbiology at the University of Arizona, whose research on household germ transmission has earned him the nickname "Dr. Germ," emphasizes the importance of regular electronic disinfection: "Phones are particular concerns because they're constantly shuttling between our hands, faces, and various surfaces. Disinfecting them at least once daily should be as routine as washing your hands."
