The rainy season, with its high humidity, poses a real challenge for handmade crafts like mother-of-pearl inlay trays. Without proper care, the inlay surface can become discolored, lose its natural shine, or even develop mold. So how can you keep your trays clean, beautiful, and mold-free throughout this damp season? Here are some simple yet highly effective care tips.

1. Avoid Direct Sunlight
Many people mistakenly place mother-of-pearl trays under direct sunlight to prevent moisture buildup. However, this can seriously damage the tray. Strong midday sun and UV rays can cause the inlay to fade, crack, or warp. Prolonged exposure also deteriorates the outer varnish or lacquer, making the tray even more vulnerable to mold. Instead, store your tray in a well-ventilated area with gentle natural light, away from direct sun exposure.
2. Keep Away from High Humidity and Damp Environments
Humidity levels rise significantly during the rainy season, especially in enclosed, poorly ventilated spaces. Excess moisture can cause the adhesive used in inlay work to expand, leading to peeling or warping of the wooden base. To prevent this, store trays in dry, ventilated places. You can also use dehumidifiers or moisture-absorbing packets in display cabinets to maintain optimal air quality. Occasionally wipe the tray with a soft, dry cloth—especially useful during humid spells.

3. Avoid Harsh Cleaning Chemicals
Many commercial cleaners contain corrosive substances that strip the natural shine from mother-of-pearl. Worse, they can weaken the bond between the inlay and the tray’s surface, causing it to peel or crack. For cleaning, only use a soft, dry, or lightly damp cloth. If needed, opt for a gentle, acid-free wood cleaner that is colorless and safe for delicate surfaces.
4. Regular Cleaning to Maintain Shine
Routine cleaning is a simple yet effective way to keep your tray free from dust and moisture buildup. Wipe the surface gently with a soft cloth to prevent mold formation. Every 1–2 months, you can apply a small amount of colorless wood wax to restore the tray’s shine. This not only enhances the tray’s appearance but also adds a protective layer that increases its longevity.

5. Store Carefully When Not in Use
When not in use, store your tray properly to avoid moisture exposure or environmental damage. Wrap it in a soft cloth or newspaper, place it in a sealed box, and store it in a cool, dry area. Avoid locations with water leaks, near windows, or damp walls—these areas are prime breeding grounds for mold. If possible, check on your tray regularly to catch early signs of moisture damage.

6. Avoid Strong Impacts and Sharp Objects
Mother-of-pearl trays are handcrafted using natural materials, making them delicate and easily damaged by force. The inlay is thin and fragile, so any impact can dislodge parts of the design, ruining its aesthetic appeal. Handle with care and avoid contact with metal or hard objects. Also, refrain from placing heavy items on the tray to prevent warping or cracking.
