Recharge: The best way to do that is to keep them in a place that gets moonlight, overnight. You can also put the crystal in salt for at least 15-20 minutes on normal nights. On full moon nights let it sit in salt overnight.

Cleansing: Once you receive your crystal, it is essential to do a cleansing and activating ritual to make this crystal YOURS! For that keep it immersed in simple salt for 5-10 minutes.
