The most stringent protocol I've seen is to store the gold melt in a glass
container (with glass lid) and handle it only with clean tweezers. I've
seen others store in glass, though. Never seen one cleaned, other than
ebeaming the hell out of it before opening the shutter.

If your melt fell in a pool of dirty water (or whatever), I would suggest
putting it in a vacuum oven first, followed by an oxygen plasma ash, then
the aforementioned ebeam cooking.

But, really: hands off is the way to go.

Subject: [mems-talk] Gold melt cleaning/storage protocol?

Hello all,

What is correct protocol for cleaning a gold melt (for ebeam) when not in
use?

Some of the suggestions that I have heard are:
(a) Immerse the melt in IPA when not in use
(b) No need to immerse it, but clean it using a fabwipe & IPA before use
(c) Hands off the melt. No need to clean it.

All comments & suggestions are welcome.
