Tip: Turning Mounting Hardware Black
Sometimes when installing a control pot rotary switch etc.
It would be nice to have the hardware black to match the panel or knob.
A simple solution that I found is to use some cold gun bluing
solution typically used for touchup on to turn the hardware black.
I normally will clean the hardware well and sometimes even
lightly sand it to get through any plating to the base metal.
(cleaning it well again after any sanding)
Put a little of the solution at the bottom of a paper cup.
Warm the hardware (a cigarette lighter is an easy way) and
drop it into the solution swirling it around until it turns black.
When done rinse well with water and lightly oil to prevent rusting
I typically buff it with a tissue or paper towel. to remove the excess
oil and the excess film of black on the hardware.

Birchwood Casey makes "Aluminum Black". Much easier than using RIT die and anodizing.
