Understanding Ivory Piano Keys
Before beginning the cleaning process, it’s important to know that ivory piano keys are organic and porous, made from the tusks of elephants, which makes them delicate. They can be damaged if not handled properly. Many pianos today do not have ivory keys due to the ban on ivory trading, but some older pianos still retain their original ivory keys.
Materials Needed
To clean ivory piano keys, you will need the following materials:
- Mild dishwashing soap
- Clean soft cloths (lint-free)
- Water
- White vinegar (optional for tough stains)
- Hydrogen peroxide (optional for whitening)
- Clear hand sanitizer (optional for disinfection)
- Protective gloves (optional for your hands)
Steps for Cleaning Ivory Piano Keys
Follow these steps to clean your ivory piano keys gently and safely:
Step 1: Prepare the Cleaning Solution
Mix a few drops of mild dishwashing soap with warm water in a small bowl. If you are dealing with tougher stains, you might consider adding a small amount of white vinegar to the solution. But be cautious, as vinegar is acidic and should only be used sparingly.
Step 2: Light Cleaning for Regular Maintenance
Moisten a soft cloth with the soap and water solution, making sure to wring it out thoroughly so it is damp, not wet. Too much moisture can seep into the ivory and cause damage.
Step 3: Wiping Down the Keys
Gently wipe the keys’ surface—key by key—from back to front to prevent moisture from seeping down the sides. Avoid using a side-to-side motion as this can transfer dirt from one key to another and allow liquid to drip between the keys.
Step 4: Removing Tough Stains
If there are stubborn stains, you can dip the cloth into a mixture of white vinegar and water (again, very sparingly), and carefully rub the affected key. Do not apply too much pressure as this could scratch the ivory.
Step 5: Disinfecting (Optional)
For disinfection, you can lightly apply clear hand sanitizer with a clean cloth if necessary, although the alcohol content may affect the ivory, so this should be done rarely and with caution.
Step 6: Whitening (Optional)
If the ivory keys have yellowed over time, applying a small amount of hydrogen peroxide with a cotton ball can help. But, this should be done infrequently and only if necessary, as it can dry out the ivory.
Step 7: Drying the Keys
Immediately after cleaning each key, use a different clean, dry soft cloth to completely dry the key. Do not let the keys air dry as this can cause the ivory to warp or crack due to moisture absorption.
Step 8: Final Touches
After all the keys have been cleaned and dried, close the piano lid to protect the keys from dust and sunlight, which can lead to further discoloration and damage to the ivory.
Preventative Care for Ivory Keys
Here are some tips for maintaining ivory piano keys and preventing the need for frequent heavy cleaning:
- Always wash your hands before playing the piano to prevent oils and dirt from transferring to the keys.
- Avoid eating or drinking around the piano.
- Keep the piano out of direct sunlight.
- Use a piano key cover when not in use to keep dust off the keys.
- Regularly air and lightly dust the keys with a soft duster.
Professional Care
If the keys are severely stained or if you are uncomfortable cleaning the keys yourself, consider contacting a professional piano technician. They have the expertise and the right materials for safely cleaning ivory keys without causing damage.
