Restoring Brilliance: A Comprehensive Guide to Cleaning Ivory

Ivory, with its smooth texture and creamy hue, has been treasured for centuries, used in everything from decorative objects to musical instruments. However, this beautiful material is also delicate and prone to discoloration and staining over time. Whether you’ve inherited a cherished ivory piece or discovered one in an antique shop, knowing how to properly clean it is crucial to preserving its beauty and value. This guide provides a comprehensive, step-by-step approach to cleaning ivory safely and effectively, ensuring you can enjoy its splendor for years to come. Before we begin, a crucial point: the sale of new ivory is restricted in many countries due to ethical concerns regarding elephant poaching. This guide pertains to the cleaning and preservation of *antique* or *vintage* ivory pieces that predate these bans.

Understanding Ivory: A Delicate Material

Before attempting to clean your ivory piece, it’s essential to understand its composition and characteristics. Ivory is primarily made of dentin, a hard, dense tissue found in the tusks and teeth of certain animals, most commonly elephants. It’s porous and relatively soft compared to other materials like stone or metal, making it susceptible to damage from harsh chemicals, abrasive cleaners, and extreme temperatures. Common issues that require cleaning include:

• Discoloration: Yellowing or browning due to age, exposure to light, or environmental factors.
• Stains: From spills, inks, or contact with other materials.
• Dirt and Grime: Accumulated dust and fingerprints.
• Surface Residue: From previous cleaning attempts or handling.

Attempting to clean ivory without understanding these factors can lead to irreversible damage, such as scratching, cracking, or further discoloration. Therefore, caution and patience are paramount throughout the entire cleaning process.

Gathering Your Supplies: Gentle is Key

The key to successful ivory cleaning is using gentle, non-abrasive materials and avoiding harsh chemicals. Here’s a list of the supplies you’ll need:

• Soft Cloths: Microfiber cloths or lint-free cotton cloths are ideal for cleaning and polishing. Avoid using paper towels, which can scratch the surface.
• Lukewarm Water: Use distilled or filtered water to avoid mineral deposits.
• Mild Dish Soap: Choose a gentle, pH-neutral dish soap without any added dyes or fragrances.
• Cotton Swabs (Q-Tips): For cleaning crevices and intricate areas.
• Soft-Bristled Brush: A soft toothbrush or artist’s brush is useful for removing dust and grime.
• Distilled White Vinegar (Optional): For tougher stains (use sparingly and cautiously).
• Baking Soda (Optional): As a mild abrasive cleaner (use sparingly and cautiously).
• Mineral Oil or Renaissance Wax (Optional): For polishing and protection (after cleaning).
• Clean Bowl or Basin: To hold the cleaning solution.
• Protective Gloves: To prevent oil and dirt transfer from your hands.
• Magnifying Glass (Optional): For close inspection of the cleaning process.

Step-by-Step Cleaning Instructions

Before you begin, it is crucial to test any cleaning solution on a small, inconspicuous area of the ivory piece. This is often on the back or bottom of the piece. If the test area shows no adverse reaction like discoloration or damage, proceed with the whole piece with caution.

Step 1: Initial Inspection and Preparation

• Examine the Ivory: Before you start, carefully examine the ivory piece for any cracks, chips, or loose parts. Note any areas of concern that may require extra care.
• Dust Removal: Gently remove loose dust and debris with a soft-bristled brush or a dry microfiber cloth. Brush in the direction of the grain, if visible, to prevent scratching.
• Set Up Your Workspace: Prepare a clean and well-lit workspace. Cover your surface with a soft towel to avoid scratching the ivory.
• Put on Gloves: Wear protective gloves to prevent the transfer of oil from your hands to the ivory.

Step 2: Gentle Cleaning with Soapy Water

• Prepare the Solution: In your bowl or basin, mix a small amount of mild dish soap with lukewarm distilled water. The solution should be very dilute; just a drop or two of soap is usually sufficient.
• Dampen a Cloth: Lightly dampen a soft cloth with the soapy water. Do not soak the cloth; it should be just slightly moist.
• Gently Wipe the Ivory: Using the damp cloth, carefully wipe the surface of the ivory. Use gentle, circular motions. Avoid applying too much pressure.
• Clean Crevices: For hard-to-reach areas, use a damp cotton swab. Gently roll the swab along the grooves and crevices to remove dirt.
• Rinse the Ivory: Once you have finished cleaning, rinse a clean, soft cloth with plain, lukewarm distilled water and use it to wipe the ivory, removing all traces of soap.
• Dry the Ivory: Use a clean, dry soft cloth to gently blot the ivory completely dry. Avoid rubbing, as this can cause scratching. Allow the ivory to air dry completely in a well-ventilated area away from direct sunlight. Ensure that moisture is completely removed as the porous nature of ivory makes it susceptible to damage from trapped water.

Step 3: Addressing Stubborn Stains (Optional and Cautious)

If soapy water isn’t enough to remove stubborn stains, proceed with these steps very carefully and cautiously. These techniques involve mild abrasives or acidic cleaners and must be used sparingly. Test each method on a small, inconspicuous area first.

Using Distilled White Vinegar (Mild Acid)

• Dilute the Vinegar: Mix one part distilled white vinegar with ten parts distilled water. This significantly weakens the acidity of the vinegar, preventing damage to the ivory.
• Apply with a Cotton Swab: Dampen a cotton swab with the diluted vinegar solution.
• Gently Dab the Stain: Gently dab the stained area with the damp swab. Do not rub. Allow the vinegar solution to sit on the stain for no more than 10-15 seconds.
• Rinse Immediately: Immediately rinse the area with a cloth dampened with clean distilled water to remove all traces of vinegar.
• Dry Thoroughly: Blot the area completely dry with a clean, soft cloth.

Using Baking Soda (Mild Abrasive)

• Create a Paste: Mix a very small amount of baking soda with a few drops of distilled water to create a thin paste. The paste should be very watery and not thick or gritty.
• Apply Carefully: Using a clean cotton swab, gently apply the paste to the stained area.
• Gently Rub (If Necessary): If the stain requires it, gently rub the paste over the stain for just a few seconds, using a soft, circular motion. Avoid excessive pressure.
• Rinse Thoroughly: Immediately rinse the area with a cloth dampened with clean distilled water to remove all traces of baking soda.
• Dry Thoroughly: Blot the area completely dry with a clean, soft cloth.

Important Note: If neither of these methods successfully removes the stain, do not attempt more aggressive cleaning methods. It is best to consult a professional conservator experienced in handling ivory.

Step 4: Polishing and Protection (Optional)

After thoroughly cleaning and drying your ivory piece, you can consider polishing it for added shine and protection. This step is optional but recommended, especially for pieces that are frequently handled. There are two options:

Mineral Oil

• Apply a Small Amount: Apply a very small amount of high-quality, food-grade mineral oil to a soft cloth.
• Gently Polish: Gently rub the oiled cloth over the ivory surface using circular motions. Do not apply too much oil, as it can attract dust and debris.
• Remove Excess Oil: Use a clean, dry soft cloth to wipe off any excess oil.

Renaissance Wax

• Apply a Small Amount: Apply a very small amount of Renaissance Wax (a micro-crystalline wax) to a soft cloth.
• Gently Polish: Gently rub the waxed cloth over the ivory surface using circular motions. Apply a very thin layer only.
• Buff: Use a clean, dry soft cloth to buff the surface until a soft shine is achieved.

General Care and Maintenance of Ivory

Once your ivory is cleaned, it’s essential to implement good maintenance practices to keep it in pristine condition. Here are some tips:

• Avoid Direct Sunlight: Prolonged exposure to sunlight can cause ivory to yellow and crack. Store ivory pieces away from direct sunlight.
• Maintain Stable Temperature and Humidity: Extreme temperatures and humidity fluctuations can damage ivory. Keep ivory in a stable environment with moderate humidity.
• Handle with Care: Handle ivory with clean hands. Avoid touching it unnecessarily to prevent the transfer of oils and dirt.
• Store Properly: Store ivory pieces in a soft, padded case or container when not on display to prevent scratches and damage.
• Clean Regularly: Dust your ivory regularly with a soft brush or dry cloth to prevent dirt and grime buildup.
• Avoid Harsh Chemicals: Never use harsh cleaning agents, bleach, or abrasive cleaners on ivory.

When to Seek Professional Help

While this guide provides detailed instructions for cleaning ivory, there are certain situations where it is best to seek professional help. You should consult a professional conservator if:

• The ivory is severely stained or discolored.
• The ivory is cracked or chipped.
• The ivory is very old or fragile.
• You are unsure about any of the cleaning methods.
• Your attempts to clean the ivory make the situation worse.

A professional conservator has the knowledge and tools to safely clean and restore delicate ivory pieces without causing further damage. They can also advise you on the best practices for ongoing care and preservation.

Ethical Considerations and Ivory

Finally, it’s crucial to be aware of the ethical implications surrounding ivory. The current international trade of new ivory is largely banned to protect endangered elephant populations. This guide focuses on cleaning *antique* and *vintage* ivory objects that predate these bans. It is never appropriate to purchase or trade in newly harvested ivory. Supporting the conservation of endangered animals is vital for the health of our planet.
