So, I have recently embraced UVC sterilization methods.  I started with a UV bag from 59S.   The point was to sterilize things like masks, phones, keys, remotes, etc.  The bag appealed to me because I could put things in it, zip closed, and sterilize.  No need to worry about additional safety gear like gloves and uv goggles.  I really like it, and thought a wand would save me a fortune on Everclear PGA.  Anyone else using UVC on grocery packaging?


I'm wondering if anyone has figured out a way to test their equipment beyond a smell test.  Heh...  I'm thinking about putting a couple of apples side by side and using the uvc on one of them to compare how long they last, but that could take a long time to give results.

I have a small and a large UV wand.  I keep the small one in my car just in case I need one but really never used and do not know if they work or really how well they work.  Does anyone here have any experience I would love to know how and what to use this light on!!

Well, I tried something.  I wanted something very visible, so I tried it on yeast.  

I put water and honey heated to 115 degrees F into two little glass bottles.  Added yeast to both and let them do their thing.

Once they were both frothy, I used a UVC wand on one bottle.  There was a definite difference in loft on the test bottle.  It didn't crown as uniformly. Afterward, I put a spoon in and swished it once in each bottle.  The foam on the test bottle collapsed.  Not much changed about the control bottle.  So, fun with science today.

While it could not kill all of the yeast, that was not the point of the experiment.  On surfaces, I believe it is effective.  It just does not penetrate.

If it's dirty, clean it first, then use the UVC to sterilize. You should be good.  Move it s-l-o-w-l-y over surfaces, preferably about an inch away.

I wanted a way to sterilize the keys on my piano without chemicals.  I think I have found it.  Use it on your pillowcases, boxes, mail, money, grocery packaging, etc.

Edited to add:  Flumom, make sure you get UVC goggles to wear for home and your car.  Regular gloves should be okay, also.  You do not want these uv lights damaging your eyes or skin.  If it can damage the DNA/RNA of bacteria and viruses,  it can damage yours.
