Black obsidian mirror

[Vovin]

Hi guys,
Sorry for my stupid question, but…
How can I clean the surface of the black obsidian mirror?

Thanks

With facial tissues and a little water, maybe finished off with spit.

Tears of a first born virgin, collected under a blood moon…Or anything you clean a regular mirror with
