Soft dry cloth
Piano heater (optional)
High-quality dust cover

Safety Guidelines

Never attempt major repairs yourself. Contact a qualified piano technician for any tuning, regulation, or significant internal work. Improper handling can cause irreversible damage.
Protect your piano from extreme temperature and humidity fluctuations. These can warp the soundboard and affect tuning stability. Use a humidifier or dehumidifier as needed.
Keep the piano away from direct sunlight and heat sources (like radiators or fireplaces) to prevent fading, cracking, and damage to the finish.

Step-by-Step Instructions

Environmental Control
- Maintain a stable environment with around 42% relative humidity and a consistent temperature. Fluctuations can damage the wood.
- Keep your piano away from direct sunlight, windows, and heat sources to prevent damage to the finish and internal components.
Environmental Control
Regular Maintenance
- Tune your piano at least twice a year, even if not frequently used, to prevent string loosening and maintain pitch stability. Hire a professional tuner.
- Regularly clean the exterior with a soft, dry cloth. Professional internal cleaning is recommended to avoid damaging delicate components.
Regular Maintenance
Playing & Handling
