UV-C light disinfection is proven science, but it’s not foolproof. Our Portable UV Light Disinfection Wand is lab tested to kill 99.9% of germs. It will only achieve those results when it is used properly. In this blog, we’ll go over some tips to use UV-C wands safely and effectively.
We’ll start with general instructions that apply to all UV-C wands. Next, I will include some specific tips for our Portable UV Light Disinfection Wand.
UV-C Wand General Use Guidelines
- Safety first! Read our Guide to UV-C Light Safety.
- Wipe down the object you will disinfect with a soft cloth to remove dirt and grime that can block UV-C rays and limit effectiveness.
- Place the object down on a surface. Never hold an object while you disinfect it!
- Hold the wand facing down to prevent accidental exposure to your eyes and turn it on with the light pointing away from you.
- Verify that it is working by shining it face down to see the light reflected on a surface. It’s not a “bright” light, and that’s okay. We cannot see UV-C light! It is not in our visible spectrum. The faint blue or purple light that you see is added by the manufacturer to let you know it is turned on and to prevent accidental exposure to your eyes and skin.
- Hold the light very close to the object you are sanitizing, just a few centimeters away. The radiation delivered is more diffuse the farther you hold it away, so it would take much longer to disinfect from several inches away.
- The effective area is about the size of the wand light, and the goal is to expose the effective area to a surface for 10 seconds to thoroughly disinfect.
- For small objects, like keys or a remote control, hold it stationary over the object for at least 10 seconds. Don’t forget to flip it over and do the other side.
- For larger objects, take 5 slow sweeps over a segment as wide as the wand light. A laptop keyboard, for example, is about twice the size of the wand. Take 5 slow passes across the top half and 5 slow passes across the bottom half.
Portable UV Light Disinfection Wand Tips
To be honest, when I first received my portable wand, I thought it was broken! Susan patiently taught me how to use it, and I want to pass those tips along to you.
- The wand has two modes of operation: battery and USB power.
- The USB cable does not charge the wand. It must be plugged into a USB port with power to turn on.
- Expect about 3 hours of operation on 4 AAA batteries.
- Hold the power button for three seconds to turn on. A bright blue light next to the power button lets you know it’s on.
- This wand has a safety feature that turns off the UV-C light when it is tilted up. Don’t think it isn’t working because it flickers when you try to look at it. It’s supposed to do that, and you’re not supposed to look at it. Verify operation by shining the faint blue light on a surface beneath it.
