Introduction: Safety Depends on Cleanliness
Face shields are a critical line of defense against chemical splashes, airborne droplets, and flying debris. But to remain effective, they must be cleaned and disinfected properly—without compromising clarity or structural integrity.
In this guide, we’ll walk you through step-by-step instructions on how to clean and disinfect face shields safely and correctly in 2025, along with product recommendations and best practices for extending their usable life.
Why Cleaning Face Shields the Right Way Matters
Improper cleaning methods can scratch the shield, degrade anti-fog or anti-scratch coatings, or even weaken the material. A foggy or damaged shield can impair visibility and compromise safety.
Recommended Cleaning Frequency
- After every use in medical, lab, or food processing environments
- Daily or weekly in construction, manufacturing, or industrial settings
- Immediately if exposed to blood, chemicals, or contaminated surfaces
Step-by-Step: How to Clean and Disinfect Your Face Shield
Step 1: Inspect the Shield
Check for cracks, warping, scratches, or loose headgear. If any damage is found, replace the shield immediately.
Step 2: Rinse with Warm Water
Gently rinse the face shield under warm (not hot) running water to remove debris, dirt, or chemical residue.
Step 3: Use Mild Soap or Approved Cleaner
Apply a mild dish soap or an ANSI-compliant lens/surface cleaner using a microfiber cloth. Avoid harsh chemicals like ammonia or bleach unless manufacturer-approved.
Step 4: Disinfect
Use an EPA-registered disinfectant approved for PPE. Spray or wipe down the surface, ensuring full contact time as listed on the product label (usually 1–4 minutes).
Step 5: Rinse Again
After disinfecting, rinse thoroughly with clean water to remove any leftover disinfectant that could degrade the plastic over time.
Step 6: Air Dry or Pat Dry
Allow the shield to air dry or use a soft, lint-free towel. Avoid paper towels, which can cause micro-scratches.
Do’s and Don’ts for Cleaning Face Shields
Do:
- Use soft microfiber cloths or lens-safe wipes
- Use cleaners specifically labeled safe for polycarbonate or PETG plastics
- Follow manufacturer instructions and OSHA recommendations
Don’t:
- Use abrasive pads or sponges
- Use alcohol-based cleaners unless specified
- Soak in bleach or hydrogen peroxide for extended periods
- Expose to high heat (e.g., dishwashers or boiling water)
Can Face Shields Be Reused?
Yes—if properly cleaned and not visibly damaged. Most reusable face shields are designed for multiple uses with correct maintenance.
Disposable face shields, however, are intended for single use and should be discarded after contamination.
Storage Tips to Prevent Damage
- Store face shields in a clean, dry area away from sunlight
- Hang vertically or lay flat in a drawer with soft padding
- Avoid stacking multiple shields without separators

Frequently Asked Questions (FAQs)
1. Can I clean a face shield with alcohol wipes?
Only if the manufacturer allows it. Alcohol can degrade certain plastic materials and anti-fog coatings over time. Always check the label first.
2. Are dish soaps safe for cleaning face shields?
Mild, non-abrasive dish soaps are generally safe for polycarbonate and PETG shields. Avoid soaps with added fragrances or scrubbing beads.
3. How do I disinfect face shields without damaging anti-fog coatings?
Use PPE-safe disinfectants designed for coated plastics and avoid soaking or prolonged exposure. Rinse thoroughly after disinfection.
4. What’s the best way to dry a face shield?
Air drying is best. You can also use a soft, lint-free towel. Never use paper towels or heat sources like hair dryers or dishwashers.
5. How do I store a clean face shield?
Store in a dry, dust-free area. Use protective sleeves or vertical racks to prevent scratching and warping.
