I am currently servicing a Wittnauer A-11 8 day aircraft clock. The hands appear to have mildew on them?? Is this possible with radioactive hands, and if so, could I use a diluted bleach solution on say a qtip to remove the mildew??

I would say that the mildew on radium hands is possible.
That said, I would not introduce any chemical to clean these. It’s impossible to know what the reaction could be.
On the few radium hands that I’ve worked on, I only wiped them clean with rodico, and wore gloves and a mask.
These radioactive elements have half-lives of may years ( 100s-1000s).
I just don’t think that without a lab setup, that we are safe to really take on the restoration of them

Hi everybody – newbie here and trying to learn what I can about my new hobby
This article will_ probably_answer any questions on luminous dials. I found it a while ago. The article is quite long and very well written. One section, for example, is titled “Reactivating Radium Paint”
Here’s another I just found:
Interesting additional info:
On a slightly different note, the following is unbelievable that some people can be so callous:
THAT’S IT … I’m done

Welcome to the forms and thank you for your input !! This clock is back to it’s owner. I decided to leave the hands as they were. Thanks again and welcome.
