How to Cleanse Crystals: 7 Methods That Work (and 3 to Avoid)

Why Crystals Need Cleansing

Whether or not you buy into energy work, there are two practical reasons to cleanse crystals. First, they pick up dust, skin oils and handling residue. Second — and this is the part that matters to most people — a stone you’ve just bought or used through a difficult period is easier to work with again once it’s been reset. Cleansing is a way of starting the relationship over.

Seven Safe Methods

1. Moonlight

The gentlest and most popular method. Place your crystals on a windowsill overnight, ideally around the full moon. It works for every stone, including the fragile ones, and costs nothing.

2. Smudging

Pass the stone through the smoke of white sage, palo santo or a herbal smudge stick for 20–30 seconds. This is the fastest method and the most satisfying — you can feel the ritual doing something. Our smudging guide covers how to do it safely.

3. Running water

Hold under a stream for a minute. Only for hard, non-porous stones (see the avoid list below). Use cold or lukewarm water, never hot.

4. Salt

Bury the stone in a bowl of sea salt or Himalayan salt overnight. Effective and traditional — but never for porous or metallic stones. Discard the salt afterwards; don’t reuse it.

5. Brown rice

An odd-sounding but genuinely useful method: bury the crystal in a bowl of dry rice overnight. The rice absorbs residue, then you throw the rice away. Popular for black stones that seem to “hold on” to things.

6. Earth

Bury in soil or a plant pot for a day or two. Slow but thorough, and it reconnects the stone to where it came from. Rinse lightly afterwards.

7. Sound

A singing bowl, tuning fork or bell — the vibration does the work and it’s safe for every stone. Good for people who work with several crystals at once.

Three Methods to Avoid

Water on soft or porous stones: selenite, halite, calcite, angelite and others dissolve or crack. Selenite in particular should never be wet.
Salt on porous or metallic stones: hematite, pyrite, magnetite and anything with metal inclusions will corrode.
Direct sunlight for long periods: amethyst, rose quartz and celestite fade. A short sunbath is fine; a week on a windowsill is not.

If you’re not sure what a stone can take, use moonlight, smudging or sound — those three are safe for everything.

How Often Should You Cleanse?

Situation	Suggested frequency
Newly bought crystals	Once, before use
Everyday carry stone	Weekly
After a difficult or emotional period	Immediately, then weekly
Display pieces you don’t handle	Monthly, mostly dusting
Crystals used in group work or by others	After each use

Cleansing vs Charging

They’re separate steps. Cleansing removes what the stone has picked up; charging restores its “fresh” state and sets its purpose. A simple sequence: cleanse first, then hold the stone, state its purpose out loud in one sentence, and leave it in moonlight or sunlight for a few hours.

If you’re working with the chakra system, cleansing becomes more important — stones moved between positions pick up a lot of handling. Our seven chakras guide sets out the full system.

That’s genuinely all you need. Everything beyond this is preference. For choosing stones in the first place, our crystal healing beginner’s guide covers the basics, and if you’re buying crystals as presents, the crystal gifts guide is a good starting point.
