How do you clean freshwater pearls?

Freshwater pearls, with their understated elegance and natural beauty, require careful maintenance to preserve their luster and charm. This guide will take you through the entire process of cleaning freshwater pearls, ensuring that they remain radiant for years to come. We will cover everything from understanding freshwater pearls to professional cleaning and storage advice.


Understanding Freshwater Pearls

Freshwater pearls are formed in mussels, predominantly found in lakes, rivers, and ponds. Unlike their saltwater counterparts, freshwater pearls are generally more abundant and come in a wider variety of shapes and sizes. They are composed mainly of nacre, the same substance that forms the inner shell of mollusks. This nacre gives pearls their unique iridescent quality.


Pearls are organic gems and are more delicate than many other gemstones. This delicacy means they require special care to prevent damage from scratches, chemicals, and extreme temperatures. Understanding the nature of freshwater pearls is the first step in ensuring their proper care and cleaning.

Cleaning Process

Cleaning freshwater pearls involves a series of careful steps to maintain their natural beauty. The process includes using a mild cleaning solution, gentle cleaning techniques, proper rinsing and drying, daily maintenance routines, and appropriate storage methods. Each step is crucial to ensure that the pearls are not only cleaned but also preserved.

Mild Cleaning Solution

The first rule of cleaning freshwater pearls is to use a mild cleaning solution. Harsh chemicals can damage the nacre and reduce the pearls’ luster. Here’s how to prepare a suitable cleaning solution:


Lukewarm water

Mild dish soap (free of ammonia and harsh chemicals)


Mix a few drops of mild dish soap into a bowl of lukewarm water. Ensure the water is not hot, as extreme temperatures can harm the pearls.

Important Notes:

Avoid using any cleaners that contain ammonia, bleach, or vinegar, as these can erode the nacre.

Do not use ultrasonic jewelry cleaners or steamers, as the vibrations and heat can damage the pearls.

Gentle Cleaning

Once you have prepared your mild cleaning solution, the next step is to clean the pearls gently. Here is a step-by-step guide:

Dipping the Cloth:

Dip a soft, lint-free cloth into the mild cleaning solution. Make sure the cloth is damp but not soaking wet.

Wiping the Pearls:

Gently wipe each pearl individually. Avoid rubbing too hard, as this can scratch the surface.

Cleaning the String:

If your pearls are strung, clean the string lightly as well. Be mindful not to stretch or damage the string, which can weaken over time.

Rinse the cloth in clean water and wipe the pearls again to remove any soap residue.

Rinsing and Drying

Proper rinsing and drying are critical to prevent water spots and potential damage. Follow these steps:


After wiping with the damp cloth, it is essential to ensure that no soap residue remains on the pearls. Rinse the pearls lightly with a separate damp cloth soaked in clean water.


Lay the pearls flat on a soft, dry towel. Gently pat them dry with another towel. Avoid using heat sources like hair dryers, as heat can cause the pearls to crack or the string to weaken.

Final Check:

Once dry, inspect the pearls for any remaining residue or dampness. Ensure they are completely dry before storing.

Daily Maintenance

Regular care and maintenance can significantly extend the life and luster of your freshwater pearls. Here are some daily maintenance tips:

Wear Often:

Pearls benefit from the natural oils in your skin, which can enhance their luster. Wearing them frequently can keep them looking their best.

Wipe After Use:

After wearing your pearls, wipe them down with a soft, dry cloth to remove any body oils, sweat, or cosmetics that may have accumulated.

Avoid Contact with Chemicals:

Pearls are sensitive to chemicals found in perfumes, hairsprays, and cosmetics. Apply these products before putting on your pearls and allow them to dry completely.

Last On, First Off:

Make pearls the last thing you put on when dressing and the first thing you take off. This minimizes their exposure to potential contaminants.

Storage Advice

Proper storage is essential to protect freshwater pearls from damage. Here are some storage tips:

Separate Storage:

Store pearls separately from other jewelry to prevent scratches. Use a soft pouch or a lined jewelry box with individual compartments.

Avoid Plastic:

Do not store pearls in plastic bags, as the chemicals in plastic can damage the nacre. Instead, use a soft cloth pouch or a jewelry box lined with felt or silk.

Moderate Humidity:

Pearls need a certain amount of moisture to maintain their luster. Store them in a slightly humid environment, but avoid excess humidity, which can weaken the string.

Avoid Direct Sunlight:

Keep pearls away from direct sunlight and extreme temperatures. Excessive heat can cause pearls to crack, and prolonged exposure to sunlight can fade their color.

Professional Cleaning

While regular at-home cleaning is sufficient for routine maintenance, professional cleaning is advisable for more thorough care, especially for valuable or antique pearls. Here’s what to consider:


Have your pearls professionally cleaned and restrung every 1-2 years, depending on how often you wear them.

Choosing a Professional:

Select a jeweler who specializes in pearls and understands their delicate nature. Not all jewelers have the expertise required to handle pearls properly.


During professional cleaning, have your pearls restrung if necessary. Ensure they are strung with knots between each pearl to prevent them from rubbing against each other and to reduce the risk of losing them if the string breaks.

What to Avoid

Understanding what to avoid is crucial in preserving the beauty and longevity of freshwater pearls. Here are some key points:

Harsh Chemicals:

Avoid exposing pearls to harsh chemicals like bleach, ammonia, and vinegar, which can damage the nacre.

Abrasive Materials:

Do not use abrasive cleaners or brushes on pearls. Even a mild abrasive can scratch their delicate surface.

Excessive Moisture:

Avoid submerging pearls in water for extended periods. While they can handle brief contact with water, prolonged exposure can weaken the string and dull the luster.

High Temperatures:

Keep pearls away from heat sources, including hair dryers, steamers, and direct sunlight. High temperatures can cause pearls to crack and the string to deteriorate.

Improper Storage:

Avoid storing pearls in dry, airtight containers for long periods. They need a bit of moisture to maintain their luster, and overly dry conditions can cause them to become brittle.


Freshwater pearls, with their unique charm and elegance, deserve meticulous care and attention. By understanding their delicate nature and following the proper cleaning process, you can ensure that your pearls remain beautiful and lustrous. Use a mild cleaning solution, clean them gently, rinse and dry them properly, and follow daily maintenance and storage advice. Avoid harsh chemicals, abrasives, excessive moisture, and high temperatures. For optimal care, seek professional cleaning periodically. With these steps, your freshwater pearls will continue to enchant and delight for generations to come.
