How to Maintain Your Upright Piano: By Professional Technicians

Upright pianos are wonderful instruments that can bring joy for decades, but they need regular care and maintenance to stay in top playing condition. Professional technicians have shared their insights on the best ways to care for your piano, ensuring it remains in optimal shape for years to come. Whether you’re a beginner or a seasoned pianist, here’s how to maintain your upright piano to keep it in tip-top shape.

  1. Regular Tuning: Why It’s Essential

Upright pianos are made from natural materials like wood and metal, which can expand and contract due to changes in humidity and temperature. This leads to your piano going out of tune. Most professional technicians recommend tuning your piano at least twice a year to maintain its sound quality.

Why Tuning Matters:

  • Keeps strings from getting overly stretched or too loose
  • Ensures consistent sound quality and pitch
  • Prevents long-term damage to the piano’s internal components

Professional Tip:

Tuning should be done by a qualified piano technician who can ensure the strings are properly balanced. Don’t try to do this yourself unless you have the right training and tools.

  1. Maintain Proper Humidity Levels

Pianos are sensitive to humidity. Too much moisture can cause the wood to swell, while too little can cause it to dry out and crack. Ideally, your piano should be kept in a room where the humidity level is between 40-50%. To maintain this, consider using a piano-specific humidifier or dehumidifier.

Effects of Improper Humidity:

  • Swelling or shrinking of wooden parts
  • Misalignment of action components
  • Rusting of the metal strings or other hardware

Professional Tip:  If you live in a very dry or very humid climate, invest in a Piano Life Saver System, which helps regulate humidity within the piano itself.

  1. Clean the Piano Exterior Regularly

Dust and dirt can accumulate on your piano’s exterior, affecting its appearance and potentially causing damage to the finish. Regular cleaning will not only keep your piano looking its best but also extend its longevity.

Cleaning Tips:

  • Use a soft, dry cloth to wipe the surface of the piano. Avoid using abrasive materials that could scratch the finish.
  • For fingerprints and smudges, lightly dampen a cloth with water (no harsh chemicals!) and gently wipe the surface.
  • Polish the keys with a damp cloth, making sure to dry them immediately afterward. Be cautious with older ivory keys, as they can be more sensitive to moisture.

Professional Tip: Avoid household cleaners or polishes, as these can damage the piano’s finish. Stick to piano-safe products recommended by technicians.

  1. Protect Your Piano from Extreme Temperatures

Just like humidity, temperature can impact your piano’s wooden components. Extreme heat can cause the wood to dry out and crack, while cold can lead to stiffness and improper functioning. Always position your piano in a stable environment away from heat sources like radiators, fireplaces, or direct sunlight.

How to Protect Your Piano from Temperature Fluctuations:

  • Keep your piano away from windows and exterior doors where drafts or direct sunlight can affect its temperature.
  • Avoid placing it near heating vents or fireplaces, which can cause uneven heat distribution.
  • If possible, maintain a consistent room temperature throughout the year.
  1. Key and Action Maintenance

The action mechanism in your upright piano consists of thousands of moving parts that work together to produce sound. Over time, these parts can become misaligned, sluggish, or noisy. Regular maintenance, such as regulating the action, adjusting the keys, and checking the hammers, is essential to keep your piano in optimal playing condition.

Signs of Action Issues:

  • Sticking or sluggish keys
  • Uneven or inconsistent key response
  • Noisy or clunky hammer action

Professional Tip: Get your action checked by a technician at least once a year. They’ll regulate the hammers, dampers, and other moving parts to ensure smooth and even playing.

  1. Keep the Interior Clean

While cleaning the outside is essential, don’t neglect the inside of your piano. Dust and debris can accumulate in the soundboard and around the strings, potentially impacting sound quality over time. Most professionals recommend having your piano professionally cleaned every few years.

How to Clean Your Piano’s Interior:

  • Never attempt to vacuum the interior yourself unless you have specific training and tools. Pianos are delicate, and incorrect cleaning can cause damage.
  • Instead, have a professional technician carefully clean and inspect the interior during routine maintenance visits.

Professional Tip: If you notice buzzing or rattling sounds, it may be due to loose debris inside the piano. Call a technician to have it inspected and cleaned.

  1. Avoid Heavy Objects on the Piano

It may be tempting to place decorative objects like vases, picture frames, or even metronomes on top of your upright piano. However, heavy objects can cause vibrations that affect the sound quality, or even damage the piano in the event of a fall.

What to Avoid:

  • Large, heavy items that could cause the soundboard to vibrate
  • Liquids such as drinks or plants, which can spill and cause damage to the piano’s finish or inner components

Professional Tip: If you must place something on top of your piano, keep it lightweight and non-liquid. If possible, use a piano cover when not in use to prevent accidental spills.

  1. Have the Piano Inspected Annually

Even with proper care, a piano’s condition will change over time. An annual inspection by a professional piano technician can identify any issues early on before they become serious problems. This is also a good time to have the piano tuned, the action regulated, and the interior cleaned.

Benefits of an Annual Inspection:

  • Early detection of potential issues
  • Ensures the piano remains in top playing condition
  • Extends the life of your piano

Professional Tip: Ask your technician to provide a detailed report after each inspection so you can track the piano’s condition over the years.
