Oily metal has no effect on the function of the orgonite so there’s no need to clean it.
Of far more importance is the size and shape of the metal particles (see the blog topic on metal shavings).

Any kind of natural crystal material can be used (crystal beads included).

The insulated spiral-form metal shavings work as inductors to absorb any ambient electromagneic radiation in the area.
The crystal material works to change the accumulated EM radiation into heat via electrostriction which allows its discharge; thus ensuring continuous operation.

The exact means by which this turns the etheric atmosphere positive remains a mystery (as indeed does the nature of orgonie energy).

Happy gifting.
