Sea salt is another effective way to cleanse your crystal. Pour the sea salt in a dish and place your crystals on top of the salt, remember to wipe your crystal with a damp cloth after that.
Most people recommend sunlight cleansing as the sun is indispensable and has very strong energy. However, do not leave your crystals under the Sun for too long as it will “drain” your crystals instead. Some crystals, like Amethyst, Rose Quartz and Smoky Quartz will become faded when left under the sun for too long. It is recommended to place your crystals under the sun for not more than 2 or 3 hrs.

Last but not least, you can Reiki your crystals and remove any negative energies from them. Sit in a quite room. Focus on your crystals and start your Reiki session. It is also good to affirm that all negatives energies will be removed. After that, you can start using your crystals again.
Enjoy your Crystals!
