Grand Piano Upkeep

Grand piano maintenance is vital for sustaining the value and sound quality of your instrument. A piano that is in great condition can be played for many years, making the investment worthwhile. In this guide, we will share our top tips on grand piano upkeep, so that you can lengthen your instrument’s lifespan, maintain its sound quality and reduce the need for repairs.

Cleaning Your Grand Piano

Keeping your grand piano clean is a fundamental part of preserving both its appearance and its musical performance. Natural oils and dirt from the player’s hands are easily transferred to the keys during use, and over time, this build-up can interfere with their responsiveness. While it is not possible to totally prevent this, regularly washing your hands before playing can significantly reduce the chance of it happening.

Dusting Your Grand Piano

The first stage of effective grand piano cleaning is regular dust removal. If left to accumulate, dust can trap moisture and settle inside the piano’s internal components. This can then contribute to mechanical or functional issues over time. When dusting your grand piano, it is important to use a soft, non-abrasive tool such as a lint-free microfibre cloth or a feather duster to protect the finish from any scratches. Weekly dusting is recommended to prevent build-up and help preserve the instrument’s condition.

Wiping Your Grand Piano

Setting aside time each month for a light, yet thorough, clean is an important part of caring for a grand piano. Using specialist piano cleaning products is highly recommended, as they are formulated without alcohol or harsh chemicals that could damage the instrument’s finish or delicate internal components.

After diluting the gentle cleaning solution with water, use a soft, clean cloth to carefully wipe the piano keys. Always clean in a vertical motion to prevent moisture from seeping between the keys. You should also make sure the cloth is only slightly damp, rather than wet. Any excess liquid should be wrung out before the cloth comes into contact with the keys.

Once the keys have been cleaned, follow up with a separate dry cloth and gently wipe them again. This final step removes any remaining moisture and helps protect the keys from liquid damage.

Storing Your Grand Piano

How and where you store your grand piano plays a significant role in protecting its sound quality and overall lifespan. Environmental factors such as humidity, moisture, temperature fluctuations and direct sunlight can all negatively affect the instrument’s structure, finish and internal components. To minimise the risk of damage, a grand piano should be placed in a carefully chosen location and supported by appropriate protective measures designed specifically for acoustic instruments.

Finding a Location For Your Grand Piano

When selecting the best location for your grand piano, it is essential to avoid placing it near windows or heat sources. Prolonged exposure to sunlight and heat can negatively impact both the instrument’s appearance and its internal components.

Direct sunlight can damage the piano’s finish, causing the wood to crack, dry or fade. These issues are particularly noticeable on mahogany, coloured finishes, and polished or stained surfaces. Excessive heat can also weaken the glue joints, potentially leading to structural problems over time.

To maintain your piano’s stability, aim to keep the room at a stable temperature of around 20℃. This helps prevent exposure to harmful dryness or moisture, preserving the piano’s performance and its lifespan.

Covering Your Grand Piano

Using a grand piano cover is an effective way to protect your instrument from dust, pet hair and other debris that could interfere with its delicate mechanisms. Covers also help safeguard the piano’s finish from scratches and everyday wear.

Before purchasing a cover, it is important to measure your grand piano carefully. Ensuring the correct size helps prevent gaps where dust particles could enter, providing maximum protection for both the keys and internal components.

Maintaining The Sound Quality of a Grand Piano

Looking after the sound quality of your grand piano is just as important as caring for its appearance. Multiple factors can alter your piano’s performance over time, such as tuning stability, wear to the action and even playing habits. By providing regular attention to these elements, you can ensure your grand piano will maintain its sound quality for years to come.

Tuning Your Grand Piano

Over time, grand pianos can fall out of tune due to the extreme tension that their strings are under. This is particularly common in the first year after a grand piano has been purchased, as the strings stretch so much.

During tuning, the tension of the piano’s strings is adjusted using a tuning hammer. This can be a complicated process, as pianos typically have over 200 strings and each one needs to be isolated in order to be tuned correctly.

It is recommended to have your grand piano tuned by a professional once or twice a year to maintain decent sound quality and instrument health. At Rimmers, we offer our own grand piano tuning service, carried out by our highly experienced technician.

Servicing Your Grand Piano

Grand piano servicing can be a very time-consuming task, often requiring a full-day visit from a professional. During a service, a piano technician will carry out various exercises, such as adjusting the internal action (regulation), lubricating moving parts and reshaping hammers (voicing).

These exercises help ensure your piano can achieve an even volume and tone quality, as well as prevent the action from feeling heavy and unresponsive.

Your grand piano should be serviced by a professional every 3-5 years. If you would like to book a grand piano service, please get in touch with the Rimmers team.

Frequently Asked Questions About Grand Pianos

How often should you clean a grand piano?

Grand pianos should typically receive a weekly dust, as well as a monthly light clean and a deep clean every 3-6 months. Sticking to this schedule will prevent any dust and debris from building up, reducing the risk of your grand piano being damaged. High-use grand pianos may require more frequent cleaning.

How long does a grand piano typically last?

The average lifespan of a grand piano can vary depending on the grade of the model. For example, consumer-grade pianos typically last between 30-50 years, whereas high-grade models can last from 50 to over 100 years. These figures also depend on how well the piano has been maintained and how often it is played.

Although the structural components typically last for these time-frames, some functions may need replacing after 40-60 years, such as the strings, hammers and felt.

How often should a grand piano be seen by a professional?

Generally speaking, a grand piano should be seen by a professional every 6-12 months for tuning and every 3-5 years for a full service. However, these timeframes can differ depending on the piano’s usage, age and environment it is stored in. It is also important to note that a grand piano in its first year of use should be seen more frequently to adjust to ‘bedding in’.
