- Identifying dirty piano keys is the first step in cleaning them.
- Different materials require different cleaning methods.
Identifying Dirty Piano Keys
Cleaning ivory piano keys is an essential part of maintaining the instrument’s appearance and longevity. However, before cleaning the keys, one must first identify the dirt and stains on them.
Dirty keys can be identified by their appearance. Ivory keys can turn yellow over time due to exposure to sunlight or cigarette smoke. Dust and grime can accumulate on the keys, making them look dull and dirty. Stains can also be present on the keys, caused by spilled liquids or oils from the player’s fingers.
To identify dirty keys, one must inspect each key closely. A bright light source can be used to illuminate the keys, making it easier to spot stains and discoloration. If the keys appear yellow or discolored, they need cleaning.
Another way to identify dirty keys is by running a finger over the surface. If the keys feel sticky or oily, they need cleaning. Dirt and grime can accumulate on the surface, making it difficult to play the instrument.
It is essential to identify the type of dirt or stain on the keys before cleaning them. Different cleaning methods are required for different types of stains. For example, yellowing keys require a different cleaning method than keys with stains caused by spilled liquids.
Preparation Before Cleaning
Before cleaning ivory piano keys, it is important to prepare the necessary materials. The following items are recommended for cleaning ivory piano keys:
- A soft cloth: A lint-free cloth, such as a microfiber cloth, is recommended to avoid leaving lint or fibers on the keys.
- A brush: A soft-bristled brush, such as a toothbrush, can be used to gently remove dirt and debris from the keys.
- Water: Warm water is recommended for cleaning ivory piano keys.
- Mild soap: A small amount of mild soap, such as dish soap or dishwashing liquid, can be added to the water to help remove dirt and grime.
- Diluted vinegar: If the keys are particularly dirty or stained, a solution of diluted vinegar (one part vinegar to two parts water) can be used to help remove stains.
To begin, it is important to remove any excess dust or debris from the keys. This can be done by gently wiping the keys with a dry cloth. It is important to wipe towards oneself to prevent dust from collecting in the gaps between the keys.
Once the keys have been wiped down, a damp cloth can be used to remove surface layer dirt and marks. The cloth should be slightly dampened with warm water and any excess water should be squeezed out to avoid damaging the ivory. It is important to avoid drenching the keys in water, as this can cause the ivory to swell and make the keys harder to play properly.
If the keys are particularly dirty or stained, a small amount of mild soap can be added to the water to help remove dirt and grime. It is important to rinse the keys thoroughly with clean water after cleaning to avoid leaving any soap residue on the keys.
For tough stains, a solution of diluted vinegar can be used to help remove stains. The solution should be applied to a soft cloth and the keys should be wiped down gently. It is important to avoid using too much vinegar, as this can cause damage to the ivory.

Understanding the Material of Piano Keys
Piano keys are the interface between the player and the instrument. They are the primary means of communicating musical ideas and emotions. The material used to make piano keys has evolved over time, from ivory to plastic and synthetic ivory. In this section, we will explore the characteristics of different materials used to make piano keys.
Ivory Keys
Ivory is a natural material that comes from the tusks of elephants. Ivory keys were commonly used on pianos until the 1950s. Ivory is a porous material that can absorb moisture and oils from the player’s fingers. This can cause the keys to discolor and become brittle over time. Ivory keys are also prone to cracking and chipping.
Plastic Keys
Plastic keys are made from a variety of materials, including acrylic, polycarbonate, and ABS. Plastic keys are non-porous and do not absorb moisture or oils. They are more durable than ivory keys and are less prone to cracking and chipping. Plastic keys can be colored to match the aesthetic of the piano.
Synthetic Ivory Keys
Synthetic ivory is a composite material that is designed to mimic the look and feel of natural ivory. Synthetic ivory is made from a combination of plastic and other materials. It is non-porous and more durable than natural ivory. Synthetic ivory keys can be colored to match the aesthetic of the piano.
White and Black Keys
Piano keys are divided into white and black keys. White keys are typically made of ivory, plastic, or synthetic ivory. Black keys are typically made of ebony or plastic. Ebony is a dense and durable wood that is resistant to wear and tear.
How do I Know if my Piano Keys are Ivory?
To identify if your piano keys are ivory, look for a fine line on the tops indicating two-piece construction, feel for a cool grainy texture, and check for yellowing over time. Real ivory may also exhibit cross-hatching patterns known as Schreger lines under magnification.
It can often be difficult to tell whether your piano keys are made of ivory, but there are a few tell-tale signs you can look for to make an educated guess.
Look for the Fine Line (Key Join)
Ivory keys are often made in two or three pieces. The most common is a two-piece construction where the thin front half is attached to the wider back half. If you look closely at the tops of the keys, you might be able to see a very fine line (or join) across the key. This indicates that the key might be made of ivory. Plastic keys are usually molded in one piece and won’t have this line.
Texture and Feel
Ivory has a distinct texture. If you run your fingernail across the key, you might feel slight undulations or a fine grain pattern, similar to what you’d feel on an animal tooth.
Ivory keys tend to feel cool to the touch, even in a warm room.
Appearance
Ivory is not perfectly white. Over time, it tends to yellow, especially if it has been exposed to sunlight or cigarette smoke. If your keys have a slightly yellow or off-white appearance, they might be ivory.
Ivory keys may also show some crazing (fine cracks) on the surface, especially on older pianos.
Schreger Lines
Under magnification, you can sometimes see cross-hatching patterns known as Schreger lines in real ivory. These are not present in plastic.
Hot Needle Test (not recommended)
This is a more invasive test, and it’s not recommended unless you’re sure you want to risk marking your key. The idea is to heat a needle and then touch it to an inconspicuous part of the key (like the back or side). Ivory will resist the hot needle and not melt easily. Plastic, however, will melt or create a small indent.
Check for a Stamp or Manufacturer’s Mark
Some newer pianos with plastic keys might have a stamp or mark indicating the materials used. This can often be found on the side of the key when it’s removed from the piano.
