How to Cleanse & Charge Crystals:
First, you want to find the target of your cleansing and choose an appropriate method.
Always trust your intuition.
Hold an intention as you are cleansing while staying focused and grounded. Focus on your crystal and bring to mind the energy you would like to program your crystal with (keep it to one).
Follow up by filling the space with positive energy to avoid negative energies rushing back in.
Here's a useful video from Hibiscus Moon on how to use some of these methods:
Store your crystals in pouches, silk, wooden boxes or anything that will shield the crystals from external energy.
If you keep them out for display then you may need to cleanse or charge more often.
