Here comes an important duty – knowing how to clean a digital piano. Essential elements in a digital piano are its keys. Both the black and white piano keys bring forth the charm of this musical instrument. Cleaning it, however, depends on its frequency of use.

Therefore, it is highly expected for a teaching institution that uses pianos to clean them regularly. This can be narrowed down to collecting fingerprints and maintaining the machine for future use.

However, if you don’t use the piano that often, then you won’t need to clean it often. So, the frequency of usage determines the frequency of cleaning.

However, this doesn’t mean you neglect your piano if you don’t use it that much. There are ways intended to maintain and ensure the keyboard always looks good any time you want to use it.

Check out the tips on how to clean a digital piano.

Before we get into it, you can use a cheap piano cleaner instead of other chemicals. 

How to Clean Digital Piano Contacts

Contacts are fully required to enable note command. Whenever a key is struck, it is responsible for registering its purpose to the PC. In other words, contacts can be termed as the key sensors. At times these contacts are affected by debris, which negatively alters their functionality.

When this happens, a piano player will find it difficult for the keyboard to register specific keynotes. Contacts cleaning may require professional help, but it is also not impossible to undertake the task on your own. With the right steps and tools, your contact keys will be good to go.

To clean the contacts, you will need to unscrew the piano to fetch the keyboard. After that, you need a cleaning solution and some cotton swabs.

The cleaning solution should at least have an alcohol content of about 91%. You can easily acquire these things from the store. Note that they are mandatory to help you clean the piano effectively.

Here are the steps:

  • Damp a cotton swab in the solution and gently wipe the black circuit contacts.
  • Do the same on the black button contacts located on the underside of the rubber strips.
  • Brush off any remaining debris gently, but make sure not to scrub off the rubber contacts as they are much vulnerable to tear.
  • Once finished, you may reinstall your contacts on to your PC. This procedure has to be done with special attention. Make sure to install the rubber strips in the same manner you found them.

How to Clean Sticky Digital Piano Keys

How to clean a digital piano

Keys get stuck due to various reasons. Some of them include percolated dust within the cracks and swelling, which is mostly the case with wooden keys. There are different ways to unstick your piano keys.

But, this will depend on the material from which they are made. For percolated dust within the cracks of the keys, you only require an easy procedure to get your keys unstuck.

Just have with you a soft cloth, a bowl with some warm water and mix with 1-2 drops of liquid soap. Slightly damp one end of the cloth inside the solution and softly wipe between the cracks. Use the other dry end of the cloth to eliminate any remaining moisture after cleaning.

If perhaps the keys of the piano are made up of wooden material, it is likely enough that they are getting stuck as a result of swelling. Swelling happens when wooden keys are exposed to humid climates or receive spills.

Avoid taking any drinks around your piano. For humidity, a dehumidifier is an excellent device to keep next to such wooden key pianos.

You may also need to unscrew your board and fix the sticky issue. However, if you find it deeply complicated, it is highly recommended that you seek professional help.

Disinfecting your piano keys is crucial. This is highly recommended during the cold and flu seasons. If two or more people use the piano, you need to clean it regularly. As pointed out earlier, before cleaning a piano first get to know what materials the keys are made from.

This will go a long way to ensure that there is safety for the keys. Avoid using chemical solutions as they may damage the keys.

Use a light vinegar solution mixed with warm water. Damp a soft cloth (lint-free) and wipe the keys towards you. Don’t use a lot of liquid as it may find its way between the sides of the keys.

This method helps to remove any stains or fingerprints on the keys and maintain an infection-free keyboard. The reason we don’t recommend the use of popular spray disinfectants is that they mess up the texture of the keys.

The use of white vinegar mixed with warm water will get your piano keys clean from infections. For ivory keys, we advise you do this only occasionally.

How to Clean an Electric Piano Keyboard

Electric piano keyboards are mostly affected by moisture. When cleaning the electric piano keyboard, the procedure followed is similar to other digital pianos.

First, you need a cleaning solution. Mix a few drops of dishwashing liquid with a bit of warm water in a small container.

Start by cleaning the white keys. Use a clean, soft, dye-free cloth and damp it slightly in the solution. Gently rub on the keys individually for better results.

Using a different dry but soft cloth, rub it gently again on the white keys for drying. For the black keys, take another clean and soft cloth. Dip it in the solution but ensure that it is only slightly wet. It should not be full of moisture as this could find its way in between the sides.

Clean the black keys one by one and also don’t forget to clean the sides. Follow the same steps for drying the black keys. You may also find a cleaning spray for your keys, and it would work just as fine.
