Or if this part comes in plain gold
(I'm not sure where this topic should go so move it if it needs to be)
I am pretty sure @Likus would know.
I believe nail polish remover would work, tho not entirely sure on that.
No, nail polish removal is a gamble. Depending on the brand you may end up with a grainy texture, as it's likely the piece will begin to melt with even the slightest application. Your best bet is brasso.
I pour some brasso onto a paper plate. Then I apply brasso to the printed area with q-tips by rubbing it around in a circular motion until the print comes off.
Brasso is highly popular and effective. Nail polish is possible, although you may want to use a fine grit sandpaper to smooth the de-printed area out.
I just use a regular eraser. Doesn't hurt the piece in anyway, and is very easy to use.
A friend of mine found that a less-abrasive toothpaste and brush can do the trick, alongside an eraser. Takes time and close care, but it works.
