Anti-fog and anti-scratch face shields
Plastic face shields are a great way to protect your face and eyes from potentially virus-laden droplets. However, they often tend to fog up, especially in cold and humid environments. This can be frustrating and even dangerous, as it impairs your vision. Fogging occurs when warm breath hits a cool surface, creating condensation.
To prevent fogging, you can purchase face shields with built-in anti-fog technology. These shields are made from anti-fog, scratch-resistant plastic or polycarbonate, which naturally helps prevent fogging. You can also test your existing shield by wearing it in a warm, humid environment and seeing if it fogs up. If it does, there are several DIY solutions you can try to prevent fogging. One option is to use a specialised anti-fog cleaning agent or spray specifically designed for plastic visors or PPE face shields. Apply it to both sides of the visor and follow the instructions carefully. Some products need to be buffed, while others just need to be dried.
Another DIY solution is to use a home remedy such as liquid dish soap, toothpaste, or wax. To use liquid dish soap, apply a small drop to a soft cloth and wipe it on the inside of the lens or face shield. Let it dry, then buff it off until you have clear vision. Alternatively, you can dilute the soap with water in a spray bottle and spray it on. For toothpaste, make sure to use an old-school variety that does not contain bleaching agents, flavour crystals, or rubbing compounds. Apply a thin layer to the inside of the lens, then gently rinse it off with water and dry it with a soft cloth. Finally, for the wax method, smear wax on the entire surface of the lens, then buff it out with a clean cloth. This will leave a thin film that prevents fog from forming.
If you are looking for a more permanent solution, you can consider purchasing an anti-fog and anti-scratch shield replacement. For example, the Uvex by Honeywell S8555 Bionic Shield Replacement Lens is a clear polycarbonate lens with anti-fog and anti-scratch coatings. Alternatively, you can look into anti-scratch coatings such as the WeeTect Anti Scratch Coating (WASC), which can be applied to safety glasses, acrylic sheets, and other plastic surfaces through spraying or dipping technology.

Face shield maintenance
Face shields are made from a variety of plastic materials, including polycarbonate and polyethylene terephthalate (also known as PET or polyester). They are designed to protect your mouth and nose and keep potentially virus-laden droplets out of your eyes.
To maintain your face shield, it is important to regularly clean and disinfect it to ensure safety and reuse. Here are some steps to properly maintain your face shield:
Cleaning
- Submerge the face shield in warm water to dislodge particulate matter.
- Add a mild liquid dish soap, like Dawn, to reduce surface tension and allow the soapy water to evenly disperse.
- Use a soft cloth or sponge to gently clean the shield.
- Rinse the shield in clear water.
- Dry with a soft cotton towel or a microfiber cloth.
Disinfecting
- Wear clean gloves to prevent germs or debris from transferring onto the shield.
- Rinse the shield with lukewarm water to remove surface dirt and dust.
- Wipe the outside with an EPA-approved disinfectant and let it sit for a few moments to kill germs.
Storage
- Store the face shield in a dry, dust-free area to prevent the accumulation of dirt and dust.
- Avoid exposure to extreme heat or harsh chemicals, as this can damage the shield.
Inspection and Replacement
- Regularly inspect your face shield for any cracks, warps, or significant damage that could impact its protection.
- Small cracks or defects, even if barely noticeable, can weaken the shield and compromise its safety.
- Avoid repairing cracks with glue or duct tape, as these methods will not restore structural integrity.
- Replace the face shield as soon as you notice any damage.
- Ensure the face shield still fits properly; it should cover your chin, reach your ears, and eliminate gaps between the headgear and your forehead.
Additional Tips
- Avoid using household glass cleaners, such as sprays with ammonia, as these can create a hazy surface.
- Do not use paper towels to wipe or dry the shield, as they can cause microscopic scratches.
- If you are worried about a specific cleaner or disinfectant damaging your face shield, test a small amount of the product in an inconspicuous area first.
By following these maintenance steps, you can keep your DIY plastic face shield clean, clear, and in good condition for prolonged use.

Face shield alternatives
Face shields are an effective way to protect against the spread of droplet-borne viruses like COVID-19. They are also easy to clean and more comfortable to wear than face masks.
If you are unable to get your hands on a face shield, there are several alternatives you can make yourself.
One option is to use a cover binder, which is much thicker than transparency film. You will also need an elastic band, scissors or a knife, and a stapler. Cut an 11" foam strip, the same width as the transparent film. Cut the elastic band to size – depending on your head size, you may need between 11" and 14". Wrap the elastic band around the transparent film so that it curves, and staple it together.
Another option is to use weather stripping, which is a one-sided adhesive, to attach the transparency film to the headband. This is a soft and comfortable option that can be worn for hours without causing soreness.
You can also make a cloth face mask at home using a variety of common fabrics. These masks are easy to carry and can be placed over the mouth and nose when interacting with others. While they are less effective than face shields, they do offer some protection.
It is important to note that face shields should fit snugly on the forehead area to prevent slippage and provide maximum protection. They should also be cleaned regularly to prevent fogging and ensure clear visibility.

Face shield protection
Face shields are an essential tool to protect yourself and others. They are typically made from clear plastic and are splash-proof, providing an extra layer of protection from respiratory droplets. Face shields are easy to clean and can be used in conjunction with a face mask for added protection. They are particularly useful for those in close contact with people who may be sick, such as healthcare workers or those caring for a COVID-19 patient at home.
There are various types of face shields available, including those with adjustable sizes to fit both adults and children. Some shields also offer anti-fog and UV protection, which can be useful in certain environments. When choosing a face shield, it is important to consider the material and ensure it is made from high-quality plastic that is scratch-resistant and provides a clear range of vision.
If you are unable to purchase a face shield, you can make your own using clear plastic or acetate, a surgical mask, and a cutter. Simply fold the clear plastic in half and cut a slanted line near the edge. Unfold the plastic and insert the surgical mask garters into the holes. You can also add protective eyewear by cutting two additional slanted lines and inserting the eyewear.
It is important to note that while face shields provide additional protection, they are open at the bottom and may not provide complete protection from respiratory droplets that enter from below. Therefore, it is recommended to wear a face mask in addition to the shield for maximum protection. Additionally, proper ventilation and a correct fit are crucial in reducing fogging on the shield, which can obstruct your vision.
