If you’ve started collecting crystals, you’ve almost certainly run into the advice to “cleanse” them — and probably a dozen conflicting opinions on how. Some methods are genuinely lovely and safe. A few, done to the wrong stone, will ruin it. After cloudy quartz, a pitted piece of selenite, and one very sad, rust-streaked stone learned the hard way, I’ve gotten cautious about which method goes with which crystal — and that’s what I want to save you from.
This guide covers eight reliable ways to cleanse your crystals, when to use each, and — just as importantly — the stones you should never expose to water, salt, or strong sun. By the end you’ll be able to keep your whole collection fresh without damaging a thing.
A quick frame before we start: cleansing crystals is a traditional and spiritual practice, not a scientifically proven process. The idea is to reset a stone’s energy and reconnect you to your intention for it. Think of it as part meaningful ritual, part good housekeeping — both of which have real value, whatever your beliefs.
Why Cleanse Crystals at All?
In crystal tradition, stones are said to absorb the energy around them as you handle and use them, gradually feeling “heavy,” dull, or less effective. Cleansing is how you clear that accumulated energy and return the crystal to a neutral, receptive state — usually followed by charging, where you re-energize it with fresh intention. (Those are two different steps; this guide covers cleansing, and you’ll find the next step in our how to charge crystals guide.)
Even setting belief aside, the habit is worthwhile. Cleansing makes you handle each stone, keeps your collection physically clean, and gives you a recurring moment to reconnect with why you chose each piece in the first place.
How Often Should You Cleanse Crystals?
There’s no rule, but useful prompts to cleanse include: when you first bring a stone home, after heavy use, after a stone has been handled by others, following an emotionally intense period, or simply whenever it feels right to you. Stones used daily (a pocket carry, a worn bracelet) benefit from more frequent cleansing than display pieces. Once you’ve done it a few times, you’ll develop your own rhythm.
A Crucial Safety Note First
Before the methods, commit this to memory: not every crystal can handle every cleansing method. Soft and water-sensitive stones can dissolve, pit, or rust; some fade in sunlight. As a rough guide, be especially careful with these:
| Avoid this method | With stones like |
|---|---|
| Water / saltwater | Selenite, satin spar, malachite, pyrite, hematite, lepidolite, halite, calcite, angelite, fluorite, turquoise |
| Salt (can scratch/dry out) | Soft stones generally, opal, turquoise, selenite |
| Direct sunlight (can fade) | Amethyst, rose quartz, citrine, fluorite, celestite, aquamarine, smoky quartz |
A simple safeguard: if you’re unsure how hard or stable a stone is, check our gemstone hardness chart, and when in doubt, use one of the no-contact methods below (sound, smoke, moonlight, or selenite) — they’re safe for virtually everything.
The 8 Methods
1. Moonlight
The gentlest, most popular, and one of the safest methods. Set your crystals on a windowsill or outside overnight, ideally under a full moon, and bring them in by morning. It works for almost every stone (no water, no fading risk from gentle moonlight) and doubles as a charging method in many traditions. If you only learn one technique, make it this one.
2. Sound
Sound cleansing uses vibration to reset a stone — a tuning fork, singing bowl, bell, or even your own voice. Place your crystals near the source and let the sound wash over them for a minute or two. It’s completely contact-free, which makes it ideal for delicate, soft, or water-sensitive stones, and it’s perfect for cleansing many crystals at once.
3. Selenite
Selenite is prized for its traditional ability to cleanse other crystals without needing cleansing itself. Simply rest your stones on a selenite plate or beside a selenite wand for a few hours. It’s contact-safe and effortless — one of the most practical tools a beginner can own. Just remember selenite itself must stay dry. (More in our selenite guide.)
4. Smoke (Smudging)
Passing a crystal through cleansing smoke — herbs like rosemary, lavender, cedar, or palo santo — is a long-standing practice across many cultures. Light the bundle, let it smolder, and draw each stone through the smoke for a few seconds. It’s safe for every crystal and pleasantly grounding. (If you use white sage, please source it ethically and respectfully, as it holds deep significance in Indigenous traditions.)
5. Running Water
Holding a stone under cool running water is a classic method — but only for hard, water-safe stones like clear quartz, amethyst, and most quartz-family crystals. Run it for under a minute, picture the water carrying away anything stagnant, and pat it dry. Never use this on the water-sensitive stones in the table above. Natural running water (a stream) is traditional; tap water is perfectly fine.
6. Earth (Burial)
Returning a stone to the earth is a deeply grounding cleanse, especially after heavy or draining use. Bury the crystal in soil (a garden or a plant pot works) for anywhere from a day to a week, marking the spot well. Skip this for soft or water-sensitive stones, since soil holds moisture, and only bury stones you don’t mind getting dirty.
7. Brown Rice
A lesser-known but gentle option: nestle a stone in a bowl of dry brown rice for several hours or overnight. The rice is said to draw out heavy energy, and because it’s dry, it suits many stones that can’t tolerate water. Discard the rice afterward rather than eating it — in tradition it has absorbed what you cleansed away.
8. Breath and Intention
The simplest method needs nothing but you. Hold the crystal, set a clear intention to clear it, and exhale a focused breath across it (some people visualize white light instead). It’s instant, free, safe for every stone, and a reminder that in this practice your own intention is the active ingredient as much as any tool.
After Cleansing: Charge Your Crystals
Cleansing clears a stone; charging refills it with purpose. Many methods overlap (moonlight cleanses and charges), but it’s worth understanding as its own step — setting a fresh intention is where a lot of the meaning lives. Walk through it in our how to charge crystals guide.

Frequently Asked Questions
Which crystals should not be cleansed in water?
Avoid water for selenite, satin spar, malachite, pyrite, hematite, lepidolite, calcite, angelite, halite, and turquoise, among others — they can dissolve, pit, or rust. Use a dry, no-contact method like sound, smoke, moonlight, or selenite instead.
How often should I cleanse my crystals?
Whenever a stone feels dull or heavy, after heavy use, after others have handled it, and always when you first bring it home. Daily-use stones benefit from more frequent cleansing than display pieces; beyond that, follow your own intuition.
Can I cleanse crystals in sunlight?
You can, but some stones fade in strong sun — amethyst, rose quartz, citrine, fluorite, and aquamarine among them. Brief morning light is gentler than harsh midday sun. When in doubt, choose moonlight instead.
Do I really need to cleanse my crystals?
There’s no scientific requirement, and nothing bad happens if you don’t. But as a ritual it keeps you connected to your stones and your intentions, and it keeps them physically clean — both genuinely worthwhile, whatever your beliefs.
Where to Go From Here
You now have eight safe ways to keep your crystals fresh — and, just as valuable, you know which stones to keep away from water, salt, and harsh sun. My advice for beginners: start with moonlight and selenite. Between those two you can cleanse almost any stone you’ll ever own, safely and with zero risk.
