Cleansing crystals is an important part of caring for your crystal collection. To cleanse your crystals, there are a few methods you can try. Smudging with sage or palo santo is a popular method for cleansing crystals. You can also use sound, either singing bowls or tuning forks, to clear the energy of your crystals. You can also simply rinse them in water or place them on a bed of salt or dry rice to cleanse them. However, it is important to avoid sunlight and moonlight when cleansing your crystals, as they can both cause damage to your crystals. With the right cleansing methods, you can keep your crystals in good condition for years to come.
