Use a white washcloth to avoid colour transfer
To whiten piano keys made of plastic, you can use a white washcloth to avoid colour transfer. First, mix a couple of drops of mild soap and warm water. Dip a white washcloth into this mixture and wring out any excess liquid. Then, gently wipe down the piano keys from top to bottom, being careful not to get any liquid into the piano.
You can also use a white washcloth with other cleaning solutions. For example, you can mix equal parts vinegar and water, dip your washcloth into the solution, and gently wipe down the keys. Be sure to use filtered water and white vinegar, and to wipe down each key individually. Another option is to mix mayonnaise, yogurt, and white toothpaste, and apply this paste to the keys with a white washcloth.
If you are cleaning ivory keys, it is important to avoid using any liquids, chemicals, or soaps. Instead, you can use a white washcloth with a very fine steel wool pad to scrub one key at a time. You can also use a white washcloth to wipe down the keys after applying lemon juice or white toothpaste to stains. Remember to immediately dry the keys after using these methods.
No matter what cleaning method you use, it is important to avoid colour transfer onto the keys. Using a white washcloth can help ensure that you do not accidentally dye the keys a different colour.

Mix dish soap with water and wipe gently
It is important to determine whether your piano keys are made of ivory or plastic before attempting to clean or whiten them. While ivory keys are more susceptible to damage from liquids, chemicals, and soaps, plastic keys are more durable and can withstand gentle cleaning solutions.
If you have plastic piano keys, one effective method to whiten them is to mix dish soap with water and wipe the keys gently. Here's a step-by-step guide to help you through the process:
Prepare the Cleaning Solution
Mix a small amount of mild dish soap with lukewarm water. The exact proportions may vary, but it's important to ensure that the mixture is mostly water, with just a few drops of soap. The goal is to create a gentle solution that effectively cleans the keys without causing any damage.
Soak a White Washcloth
Take a clean, white washcloth and soak it in the prepared cleaning solution. Make sure to wring out the excess liquid from the cloth. You want the cloth to be damp, but not dripping wet, to avoid getting excess water into the keys, which can cause damage to the piano's mechanics.
Wipe the Piano Keys Gently
Using the damp washcloth, gently wipe down each piano key from top to bottom. Avoid wiping side to side, as this can cause the water to seep into the sides of the keys. Take your time and work on one key at a time, ensuring that you don't apply too much pressure. This gentle motion will help remove dirt, dust, and fingerprints, restoring the whiteness of the keys.
Dry the Keys
After cleaning the keys, it's important to dry them thoroughly. Use a clean, soft, absorbent cloth, such as a microfiber cloth, to wipe down the keys and remove any remaining moisture. Make sure the keys are completely dry before closing the piano's key cover. Proper drying ensures that the piano keys stay in good condition and helps prevent the growth of mould or mildew.
Precautions and Tips:
- Always test the cleaning solution on a small, inconspicuous area of the piano first to ensure it doesn't cause any discolouration or damage.
- Avoid using harsh chemicals, such as bleach or ammonia, as they can damage the keys and affect their appearance.
- Never allow excess liquid to seep between the keys or into the keybed, as it can cause swelling and affect the functionality of the keys.
- For more aggressive stains or fingerprints, you can also try using a solution of filtered water and white vinegar, but always test it first on a small area.

Use diluted vinegar to disinfect
It is important to establish whether your piano keys are made of ivory or plastic before attempting to clean them. Ivory keys are more prone to damage and should be treated with caution. When cleaning ivory keys, avoid using any liquids, chemicals, or soaps, and instead, opt for a white cotton glove or a very fine steel wool pad to scrub one key at a time gently.
Plastic keys, on the other hand, are more flexible and less susceptible to damage, allowing for a wider range of cleaning options. If your plastic piano keys are yellowing, it may be due to oxidation, UV exposure, or the acid from fingers. To whiten them, you can try various methods, including using a white vinyl eraser, a damp washcloth with a few drops of dish soap, or a mixture of bicarbonate of soda and warm water.
If you are specifically interested in disinfecting your piano keys with diluted vinegar, here is a detailed guide:
Diluted vinegar can be used as a disinfectant on plastic piano keys. Vinegar has long been known for its cleaning and disinfecting properties, and it can be an effective and inexpensive option for keeping your piano keys clean. However, it is essential to use it correctly to avoid any potential damage to the keys.
Firstly, always use white vinegar, as other types may contain dyes or additives that could stain the keys. For dilution, mix one part vinegar with three parts filtered water. This dilution ratio ensures that the vinegar is effective at killing germs without being too strong, which could damage the keys.
Before applying the diluted vinegar to the keys, ensure that you use a clean, white washcloth. Coloured cloths may transfer their dye to the keys, causing unwanted discolouration. Dip the cloth into the diluted vinegar solution, ensuring that it is damp but not dripping wet. You do not want excess liquid seeping into the keys, as this could cause damage.
Gently wipe each key with the damp cloth, focusing on one key at a time. Start from the back of each key and move towards you, covering the entire surface. Be cautious not to get any liquid between the keys, as this could affect the piano's mechanics. After cleaning all the keys, go over them again with a damp cloth that does not contain vinegar to remove any residual vinegar solution. Finally, dry the keys thoroughly with a soft, dry cloth.
While diluted vinegar can be effective for disinfecting, it may not be suitable for removing stubborn stains or fingerprints. In such cases, other methods, like using a mild dish soap or toothpaste, might be more effective. Additionally, always ensure proper ventilation when using vinegar due to its strong odour.
By following these steps, you can safely and effectively disinfect your plastic piano keys with diluted vinegar, keeping your piano clean and germ-free. Remember to be gentle and cautious during the process, as the keys can be delicate.

Avoid liquid, chemicals, or soaps on ivory keys
If you have a piano with ivory keys, it is important to take extra care when cleaning them. Antique pianos, in particular, are often made of two parts of ivory, and rubbing them excessively may cause one of the halves to detach.
Ivory is a porous material that can become discoloured easily. To maintain their pristine finish, it is best to avoid using any liquids, chemicals, or soaps on ivory keys. A good rule of thumb is to use a slightly damp cloth to clean them. Start by dusting the keys with a soft duster or a paintbrush with extra-soft bristles, always dusting away from the piano to avoid dirt buildup within the piano's cracks. Then, wet a light-coloured cloth—white is ideal—with warm water and ring it out to ensure it is only slightly damp. You can then wipe down the keys with this cloth, focusing on one key at a time. Make sure to wipe from top to bottom and not side to side, as this can damage the keys.
If your ivory keys are stained or yellowed, you can try using a white vinyl eraser to gently erase the stains, focusing on one key at a time. Alternatively, you can apply a small amount of mild, fragrance-free, and chemical-free soap to the damp cloth before wiping down the keys. However, be very cautious with the amount of soap and water used, as you do not want the cloth to be dripping wet or drenched in soap. Excess water can damage the ivory and cause the keys to swell, making them harder to play.
If you are looking to whiten ivory keys, there are a few unconventional methods you can try. One option is to apply plain yogurt lightly to the keys, letting it sit for 30 minutes before wiping it away with a damp cloth. Another method is to use milk, which contains fatty acids and calcium that can clean and protect the ivory due to its similarity to dental bone. Apply a small amount of milk to a damp cloth and then wipe down each key from top to bottom. You can also try using non-coloured toothpaste, which can help brighten the keys.

Use a fine steel wool pad to scrub
If your piano keys are made of plastic, you can use a fine steel wool pad to scrub them gently and cautiously. It is important to work on one key at a time and to be as gentle as possible to avoid damaging the keys. This method is not recommended for ivory keys, as they are more delicate and can be damaged by harsh scrubbing.
When using a fine steel wool pad to scrub your plastic piano keys, it is important to move the pad in the same direction as the keys, rather than in a back-and-forth motion, to avoid scratching the surface. You should also avoid applying too much pressure, as this could damage the keys or push the steel wool into the crevices between the keys.
It is also recommended to wear gloves while scrubbing your piano keys with steel wool, to prevent the transfer of dirt and oils from your hands onto the keys. You can use a soft cloth, such as a microfiber cloth, to wipe down the keys before and after scrubbing to remove any loose dirt or dust.
If your piano keys have stubborn stains or discolouration, you may need to use a mild cleaning solution in addition to the steel wool. For example, you can mix a few drops of mild soap or dish soap with water and apply it to the keys with a soft cloth before scrubbing with the steel wool. Be sure to wipe away any excess liquid after cleaning, as too much moisture can damage the keys.
It is always important to test any cleaning method on a small, inconspicuous area of the piano first to ensure that it does not cause any damage. Additionally, regular maintenance and cleaning of your piano keys will help to prevent the build-up of dirt and discolouration, reducing the need for more intensive cleaning methods.
