How to Cleanse Your Crystals: 7 Methods, Honest Pros and Cons

If you have ever bought a crystal and then wondered what to do with it next, you are not alone. The most common question we get at the shop, after where it came from and how much, is how do I cleanse it. There is a lot of advice on the internet about this. Some of it is great. Some of it will ruin your stones. This is our honest guide.

We are James and Deborah, and we have run Crystal Empire Gems in Grass Valley, California since 2015. We work with stones every day. We have learned which methods are safe for which crystals through real-life trial, including a few stones we wish we had treated better. Here are seven cleansing methods, what each is good for, and what to avoid.

First, what does cleansing even mean?

There are two ways to think about cleansing. The geological way: physical dust, oil from hands, and grime build up on a stone over time. It needs occasional cleaning. The traditional way: people across many cultures have described stones as picking up something during use and wanting a reset before the next round. We do not ask you to pick one view. Both are valid. The methods below work for both reasons.

How often should you cleanse? There is no rule. Some people do it monthly. Some do it after every use. A good practical rule is: cleanse a new stone when you bring it home, and cleanse any stone that you have been carrying through a long or heavy stretch of life. Beyond that, follow your gut.

Method 1: Running water

Hold the stone under cool running water for thirty seconds to a minute. Tap water is fine. Some people prefer a stream or a creek. Pat the stone dry.

Good for: clear quartz, smoky quartz, amethyst, citrine, rose quartz, carnelian, tigers eye, agate, jasper, hematite (if dried quickly), most quartz family stones.

Avoid for: selenite, malachite, pyrite, halite, calcite, fluorite (long soaks), turquoise, lapis lazuli, and any stone you are unsure about. Some of these are water-soluble. Some are porous and will lose their polish. When in doubt, skip water.

Method 2: Moonlight

Set your stones on a windowsill overnight under the moon. The full moon is the traditional favorite, but any moonlit night works. This is the safest method we know. It works for every stone. Some people also do this as a charging step rather than a cleansing step. Both are fine. You can do both at once.

Good for: every crystal. Even the fragile ones. Glass and stone do not mind the moon.

Avoid: leaving them on a windowsill into the next afternoon. Most stones that fade in sun (amethyst, rose quartz, citrine, fluorite, kunzite) will lose color if you forget them there for days. Bring them in by morning.

Method 3: Sunlight

A short morning sunbath, fifteen to thirty minutes, is fine for many stones. Some people swear by it. We use it occasionally, but we always set a timer.

Good for: clear quartz, smoky quartz, carnelian, citrine (briefly), tigers eye, jasper, agate.

Avoid for: amethyst, rose quartz, fluorite, kunzite, opal, celestite. These fade. Long sun is the single fastest way to ruin a beautiful purple amethyst geode.

Method 4: Smoke (sage, palo santo, cedar, mugwort)

Pass your stone through the smoke of a smoldering bundle of dried herbs. Sage is the most common. Cedar, mugwort, sweetgrass, and palo santo are also used. Hold the stone in the smoke for thirty seconds or so.

Good for: every crystal. Smoke is gentle, dry, and works for any mineral.

Worth knowing: some traditions around white sage and palo santo have been overharvested or come from cultures where these herbs are sacred. We carry sage we trust the source of, and we are upfront about origins. If this matters to you, ask. Cedar from your own region or homegrown rosemary works just as well.

Method 5: Selenite or kyanite contact

This is our most-used method in the shop. Place your stones on a flat slab of selenite, or set them near a piece of kyanite. Many people believe these two stones do not need cleansing themselves and can clear other stones by contact. We are not going to claim to know why this works for so many people. We just know our customers come back and say it does.

Good for: every crystal. The stone is just sitting on another stone. There is no water, no smoke, no heat.

Avoid: getting your selenite slab wet. Wipe it with a dry cloth only.

Method 6: Sound

A tuning fork, a singing bowl, or a Tibetan bell. Hold the stone near the sound source and ring or strike the instrument. People describe the vibration as moving through the stone.

Good for: every crystal. This is one of the gentlest methods.

Worth knowing: we host sound healing events on the fourth Sunday of every month at the shop, and a lot of people bring their crystals along. If you have never heard a big quartz bowl in a small room, it is worth experiencing once.

Method 7: Earth

Bury the stone in soil overnight or for a few days. Outdoor garden soil works. A pot of houseplant soil works.

Good for: most hardy stones, especially ones that feel heavy or that you have been carrying through a difficult stretch.

Avoid for: anything porous, anything water-soluble that might meet damp soil, and any stone you are afraid you will lose. Mark the spot.

Stones to be careful with

Here is a short list to memorize, because almost every honest care guide will include it. Avoid water on: selenite, malachite, pyrite, halite, hematite (long soaks rust it), turquoise, lapis lazuli, calcite, kyanite, angelite, and any soft mineral under Mohs 5. Avoid long sun on: amethyst, rose quartz, citrine, fluorite, kunzite, opal, celestite. We have a full guide on how to store your crystal collection that covers the longer list.

What we actually do at the shop

For most stones, we use selenite contact and an occasional sage smoke. For new specimens, we rinse the safe ones, smoke the others, and let everything sit on a selenite slab overnight before they go into the case. It is a calm, low-effort routine. You do not need to do more than this at home.

If you forget to cleanse a stone for a while, nothing bad happens. We have stones in our personal collection we have not formally cleansed in years. They are fine. The practice is mostly for you, not for the stone. Think of it less as maintenance and more as a small ritual that creates a pause in your day. The pause is half the point.

One last thing worth saying out loud. None of these methods are magic. They are practices. The shift you feel after cleansing a stone is real, but it is real in the way a tidied desk feels different than a cluttered one. The stone has not changed at the atomic level. You have. That is enough.

We will help you figure out which method suits your space and routine. If you are far away, this guide is most of what we would tell you in person anyway.

Quick FAQ

How often should I cleanse my crystals?

There is no rule. Cleanse new stones when you bring them home, and any stone you have been working with through a heavy stretch. Beyond that, do what feels right.

Can I cleanse all my stones at once?

Yes. Moonlight, smoke, sound, and selenite contact all work in bulk.

Do tumbled stones need cleansing too?

Same advice as raw. The shape does not change the practice.

Is salt water safe?

We do not recommend it. Salt damages many stones over time. There are safer methods.
