Splish, Splash: How to Clean Your Sharpening Stone with Water


Sharpening stones are the unsung heroes of the kitchen, keeping our knives at their sharpest. However, these useful tools require their own care and maintenance to ensure they continue to perform optimally. Cleaning a sharpening stone is an important part of this maintenance, and water often plays a significant role in the process. But is water enough? Let’s explore how you can effectively use water to clean your sharpening stone.

Why Clean Your Sharpening Stone?

A sharpening stone removes tiny fragments of metal from the blade, which then mix with the sharpening debris to create a slurry on the stone's surface. This slurry actually aids the sharpening process by acting as an additional abrasive.

However, if left unattended, this slurry can clog the stone's surface, reducing its effectiveness. Dried-on slurry can also create uneven spots on the stone, leading to inconsistent sharpening. Regular cleaning prevents this build-up, keeping your stone in top condition and ensuring it provides a sharp, even edge every time.

Cleaning with Water: The Basics

Water is a simple and readily available tool for cleaning most types of sharpening stones. It is effective at loosening and washing away the metal particles and sharpening debris that form the slurry.

After each sharpening session, rinse your stone under running water. Use a soft brush, like a toothbrush, to gently scrub the surface and dislodge any particles that are stuck in the pores of the stone. Be careful not to scrub too hard, as you don't want to wear down the stone unnecessarily.

Once you've scrubbed the stone, rinse it again to wash away any loosened debris. Then, wipe the stone with a clean, dry cloth and leave it to air-dry completely before storing it. Make sure to store your stone in a dry place to prevent any potential for mold or mildew growth.

Remember, water is usually sufficient for cleaning oil stones and water stones. However, if you're using a diamond or ceramic stone, you should follow the manufacturer's cleaning instructions, as these types of stones can sometimes require specific care.

Dealing with Persistent Debris

Sometimes, simply cleaning your stone with water isn't enough to remove all the debris, particularly if the stone hasn't been cleaned in a while. In these cases, you may need to use a cleaning agent.

A mild dish soap can help to break down stubborn grime. Add a few drops of the soap to the wet stone, then scrub gently with your brush. Once you've cleaned the stone, rinse it thoroughly to ensure no soap residue remains, as this could affect the stone's sharpening ability.

For particularly stubborn debris, a specialized stone cleaner can be used. These cleaners are designed to deeply penetrate the stone's pores and remove any lodged particles. However, they should be used sparingly and only as needed, as overuse can potentially damage the stone.

Maintaining Your Sharpening Stone

In addition to regular cleaning, your sharpening stone may also require periodic flattening. Over time, the stone's surface can become dished or uneven due to repeated use. This unevenness can lead to inconsistent sharpening results.

To flatten your stone, you can use a lapping plate or a flattening stone. These tools are designed to wear down the high points on your stone's surface, returning it to a flat and even condition.

It's also important to remember to properly soak your water stone before each use. This soaking process helps to prevent the stone from clogging up as quickly during sharpening and makes the stone more effective.


Keeping your sharpening stone clean is just as important as keeping your knives sharp. Regular cleaning with water helps to ensure your stone continues to perform at its best, providing a sharp, even edge every time.

After each sharpening session, take a few minutes to rinse your stone under running water, scrub away any remaining debris, and then leave it to air-dry completely. For stubborn debris, a mild dish soap or specialized stone cleaner can be used.

Remember, taking care of your sharpening stone not only prolongs its lifespan but also ensures your knives are always at their sharpest. After all, a well-maintained sharpening stone is the key to a well-maintained knife. Happy sharpening!
