Cleaning mica frame

#1

Post by Arrowman1 »

Ideas to clean the globe frame for a 220 slant?
Anyone put these in the ultrasonic?
The mica is pretty nice but has a couple spots where it is separated a little so a soak may not be ideal.
I don't mind the tedious job of cleaning it by hand just interested in something more thorough.
Thanks

I would not recommend putting mica in an ultrasonic cleaner. You are likely to end up with lots of little piece of mica.

If it is still nice i would leave it alone.

evaporust or citric acid soak. I had good luck with both and probably better luck with the evaporust. Rinse well and dry fast so it doesnt flash rust. I usually hit the whole thing carefully with a low flame of my torch to dry. water between the mica with boil off and can pop but so far hasnt been a problem.

Just what is on the frame that needs cleaning, grease, rust, or other? Mica is a layered material so delamination might need to be considered in what is done.

The frame has surface rust.
Delamination is what I'm worried about, and water or cleaner between the layers.
The lantern cleaned up nice..makes it hard to leave the globe as is,but that's probably the right thing to do.

Evaporust overnight then into a 200° oven for an hour or so. I've had no flash rust occur after that and no discoloration of the mica.
