Lubricating Key Bushings – Piano Tuning & Repair I HOWARD PIANO INDUSTRIES
1. Micro-Fine PTFE (Teflon) Powder
Micro-fine PTFE powder serves as a reliable dry lubricant for piano actions, forming a thin layer that minimizes friction while also repelling dust.
Why It Works for Piano Action Parts
This powder shines when applied to areas like key bushings, where it enhances smoothness without causing the felt to swell. It’s also highly effective for metal-to-metal contact points, such as hammer flange screws, bridle wire connections, and damper lever pivots. For parts like repetition mechanisms and jack springs – where traditional oils can attract dust – PTFE powder offers a cleaner, more efficient alternative. Its performance is further enhanced by the ability to apply it with precision.
Precision in Application
One standout feature of PTFE powder is how precisely it can be applied. Using a small brush, you can target delicate components like felt hammers and dampers. This level of control is essential since excess lubricant in these areas could lead to issues.
Durable Performance
PTFE powder holds up well in both humid and dry conditions, maintaining its lubricating properties over long periods. This durability helps reduce the need for frequent maintenance.
Things to Watch Out For
While PTFE powder has many advantages, it demands careful handling. Over-applying it can backfire, leading to increased friction or a gritty texture in the action. It’s also crucial to apply it only to clean surfaces to avoid trapping dirt or debris. Finally, while it’s excellent for reducing friction, it’s most effective as part of a regular maintenance routine – not as a fix for components that are already severely worn.
2. Silicone-Based Sprays (e.g., KEL Pure Silicone)
Silicone-based sprays offer a wet lubricant solution that effectively penetrates moving parts while delivering long-lasting protection. These sprays create a thin, slippery film that reduces friction without the mess typically associated with conventional oils. Their precise application makes them ideal for critical action parts in pianos.
Effectiveness for Piano Action Parts
Silicone sprays are particularly effective for metal pivot points, where smooth movement is crucial. They excel in lubricating hammer flanges, wippen assemblies, and damper lever mechanisms. Thanks to the spray format, the lubricant can reach tight spaces and enclosed pivot mechanisms that powdered lubricants might miss.
Another advantage is silicone’s molecular structure, which forms a durable barrier during continuous motion. Unlike petroleum-based oils, silicone maintains its viscosity even with temperature fluctuations, ensuring consistent performance – whether your piano is in a cool basement or a warm living room.
Application Ease and Precision
The spray delivery system makes applying silicone-based lubricants relatively simple, but precision is key. Using an extension tube helps direct the spray exactly where it’s needed, which is critical when working near felt components that must remain free of lubricant.
You can adjust the amount applied by controlling your distance from the target area and the spray duration. A light mist from about 6–8 inches away usually provides enough coverage without oversaturating the area. Silicone’s quick drying time allows for immediate inspection, and you can easily apply more if necessary.
Longevity and Stability
Silicone-based lubricants are known for their durability, staying effective longer than traditional oils. They resist being washed away by moisture in the air and hold up well under mechanical stress, which means maintenance intervals can be extended.
Additionally, silicone is chemically inert, meaning it won’t react with metal components or cause corrosion. This makes it especially valuable for older pianos, where metal parts may already show signs of wear.
Potential Risks or Drawbacks
The main risk with silicone-based sprays is overspray. If the lubricant accidentally contacts felt bushings, hammer felt, or damper felt, it can cause these materials to swell or become sticky. Such contamination often requires professional cleaning or even replacement of the affected components.
Silicone also tends to attract and hold dust more readily than dry lubricants. Some formulations may leave a slightly tacky residue, which could increase friction if applied too heavily or if dust accumulates on the treated surfaces. The spray format itself can make precise application challenging, and masking sensitive areas may be necessary to avoid unintended damage.
3. Protek CLP and Similar Multi-Purpose Lubricants
Multi-purpose lubricants like Protek CLP combine three essential functions – cleaning, lubrication, and protection – into one product. They serve as a versatile alternative to dry lubricants and silicone sprays, particularly when dealing with older components that may be grimy or worn.
Effectiveness for Piano Action Parts
These lubricants shine in situations involving metal-to-metal contact, especially when both cleaning and lubrication are needed. They’re particularly helpful for older pianos where dirt, old grease, or oxidation may have built up around pivot points. By cleaning and lubricating simultaneously, they reduce friction and help prevent corrosion. Additionally, their protective additives create a barrier against future rust or wear.
That said, multi-purpose lubricants aren’t as specialized as products designed exclusively for piano mechanisms. While they work well for most action parts, they may not provide the same precision or long-term performance as dedicated piano lubricants.
Application Ease and Precision
The liquid consistency of most multi-purpose lubricants makes them easy to apply with precision tools like needle-tip applicators or small brushes. This allows for controlled application, minimizing the chances of over-lubrication. Their cleaning properties also enable direct use on dirty surfaces without requiring extensive pre-cleaning.
Once applied, these lubricants deliver reliable performance and maintain their stability over time.
Longevity and Stability
Compared to basic oils, multi-purpose lubricants offer better longevity. The corrosion inhibitors they contain provide extended protection between maintenance sessions, and their stability across temperature variations ensures consistent performance in both warm and cool environments. These formulations are also designed to endure mechanical stress, which is crucial for the constant movement of a piano’s action components.
Potential Risks or Drawbacks
Despite their benefits, the complex formulation of multi-purpose lubricants can sometimes pose risks. The cleaning agents and additives that make them versatile might interact unpredictably with certain materials. For example, their cleaning action could strip away existing lubricant layers, requiring reapplication. Additionally, solvents in some formulations might inadvertently damage delicate felt components if applied incorrectly.
Careful application is key to avoiding these issues. Always test a lubricant on a small, hidden area before widespread use. If you’re unsure about what’s best for your piano, consulting a professional can save you time and potential headaches.

Designed with piano-specific materials in mind – like wood, felt, and metal – these greases deliver precise lubrication. For instance, Yamaha’s grease is commonly used on repetition springs and jack mechanisms, ensuring smooth operation while maintaining the piano’s natural touch and responsiveness.
The thick consistency of these greases keeps them firmly in place, even with continuous use. Unlike lighter oils that may evaporate or migrate, these greases provide reliable lubrication over time. This is especially beneficial for grand pianos, where the constant movement and effects of gravity demand durable and stable lubricants.
Application Ease and Precision
Applying piano action grease requires care and accuracy. Its thicker texture prevents it from running or dripping onto delicate felt components, which could otherwise lead to issues. To prevent over-application, technicians often use precision tools like small brushes, applying only the necessary amount to avoid attracting dust or causing sluggish action.
In some cases, technicians gently warm the grease before applying it. This helps it spread evenly across pivot points and bearing surfaces, ensuring a smooth and consistent action. Proper application not only enhances performance but also extends the time between maintenance sessions.
Longevity and Stability
These greases are highly durable, offering long-lasting protection even in pianos that are played frequently. Their formulations are designed to perform reliably across a range of temperatures, ensuring the piano remains responsive regardless of seasonal changes.
Steinway’s grease, for example, is developed to maintain its consistency – neither becoming too thick in colder conditions nor too thin in warmer ones. This balance ensures that pianists can enjoy consistent touch and precise response, no matter the environment.
Potential Risks or Drawbacks
One challenge with piano action greases is their permanence. Once applied, removing them completely can be difficult, which makes careful and precise application essential. Over-application can lead to a sluggish action feel, potentially requiring professional intervention to correct.
Another consideration is cost. Branded greases from manufacturers like Yamaha or Steinway are typically more expensive than generic options. However, since only small amounts are needed per application, a single container can last for years, servicing multiple pianos.
Over time, some greases may darken when exposed to dust. While this is only a cosmetic issue, it’s one reason many technicians reserve these greases for internal mechanisms where appearance matters less.
For the best results, consult an experienced piano technician who can recommend the most suitable grease for your piano’s specific needs.
