Method with a Candle: Light the candle and place the rhodochrosite in front of you. Imagine a white light from the flame surrounding the stone, cleansing it of negativity. Concentrate on your desire to wash and purify the stone.
Soil Method: To cleanse the Rhodochrosite, bury it in garden soil or a container for 24 hours.
Moonlight Method: Place the rhodochrosite in a safe place, such as a windowsill, on a full moon night and let the moonlight cleanse it overnight.
