How to test if UVC LED is working?

[Cyparagon]

Tell me, do those in the medical profession re-use and sanitize their masks with UVC lights in a toaster oven?

I don't know about the masks but for mold under your house a little bleach mixed with water sprayed on the mold will usually kill it.

Thanks. Are there any other chemicals like alcohol or something good for that? There's mold on stuff I might not want to risk bleach on.

Lysol, quantenary ammonia, hydrogen peroxide, peracetic acid, ethanol......

I had a friend who worked construction, and he said after bleach, they used a borax solution, as it would help prevent it from returning.
