oily magnesium turnings


I have some Mg turnings and they are coated with an oily type substance. I tried to clean some with diethyl E, but that didn't seam to work all that great and when used didn't do too well. Could I use a hydrocarbon to wash them, then ether wash? Suggestions welcome and thank you.

Light petroleum distillate should be able to take the oily substance off (hopefully). Since it is fairly volatile it won't leave a slick coating on them after cleaning.

Ether didn't work well? Might try Acetone, or the cheapest of all common non-polar solvents...Gasoline! Seems like those turnings must be coated with something that is either too polar, is too non-polar, or is polymerized.

Next up, Methylene Chloride!

Ether dissolves most things, but a gummy drying-oil might resist it.

Cleaning Mg turnings


Greets,
Have you thought about trisodium phosphate?
We use it to clean metals that will see O2. They have to be really clean
Cheers

Hi Dwarvensilver
Please, comment on that cleaning.
Molten salt?
