Maintenance
Proper maintenance ensures the longevity and optimal performance of your Donner DDP-80 Digital Piano and Duet Piano Bench.
- Cleaning: Use a soft, dry cloth to wipe down the piano and bench surfaces. For stubborn marks, a slightly damp cloth can be used, followed immediately by a dry cloth. Avoid abrasive cleaners or solvents.
- Environment: Keep the piano away from direct sunlight, extreme temperatures, and high humidity, as these can damage the wood finish and internal components.
- Dust Protection: When not in use, cover the piano with a dust cover to prevent dust accumulation on the keys and internal mechanisms.
- Bench Care: The synthetic leather seat of the bench can be wiped clean with a damp cloth. Avoid sharp objects that could puncture the material.
