Homebrew PCBs

Hi guys,

I have some Ferric Chloride I did not store properly. I thought it was 
in an airtight container, but obviously not as the powder has changed 
colors in areas.  I am assuming this is because the powder took on 
some moisture.

I believe it will still be okay to use, but before I mix up the batch, 
I figure I would ask first if there are any problems using it?

Thanks

Chris
