Using Ultra Sonic Cleaner to Clean and Clear Crystals??

[Aion]

I think I may have read that incese and sage smoke can also cleanse crystals.

Yeah those can work well too, although it would depend on the kind of incense. Some will just 'colour' the energy rather than cleanse. Sage is the classic 'smudge' plant, but something like Palo Santo would work well too. I have found, personally, that cleansing with smoke is harder to smooth out heavy distortions but works for well for any light or outer layer work.
