Salt is an excellent purifier which is why it is often used to create lamps (such as himalayan salt lamps) to help cleanse spaces and draw out unwanted energies and has been used as a protective and cleansing element for hundreds of years. The best salts to use is either sea salt or himalayan salt, do not use table salt as it contains aluminium and can be damaging.

 

In order to use dry salt to cleanse your crystal, fill a vessel (do not use metal or plastic) with salt - a shallow bowl or glass will do and put your crystals in it partially burying them. Simply leave them there for a few hours or overnight to give the salt time to work its magic.

As with all the methods mentioned please ensure that you do some research into your crystals to ensure that they are not damaged, contact with salt can be potentially damaging to some stones.
