Petaltone produces this amazing essence cleanses crystals, and also clears negative energies from buildings/persons. To cleanse crystals/minerals, just hold the bottle about 30cm / 12” above the crystals/minerals and give a couple of sprays and allow the mist to drift onto them. To clear buildings, spray around fairly liberally. Notice the difference!! Excellent for healers also, to clear the workspace in between clients. This stuff really works.
