The UV flashlight I bought for the fluorescent minerals in our rock collection came in handy in an unexpected way.

Got some turmeric stains on my shirt last night while making Indian food.

Sunlight has long been used to get out turmeric stains (the UV in sunlight does the trick). After a pre-soak in OxiClean, the stain turned bright purple due to the pH change. After 10 minutes in front of the UV flashlight, the stain was gone. #laundry #cleaning #cooking #turmeric

@adam this is good info to know. I'm gonna try to file that away somewhere in my brain for later use. It's gotta be shortwave UV, I assume?

@Mutedog I have a 390 nm and a 365 nm flashlight each. Both seem to work, but I feel like the 365 is doing a bit better job. So all longer wavelength UVA thankfully.
