If your digital piano keys are only lightly soiled, distilled water can be an effective and safe cleaning agent. Dampen a soft cloth with distilled water and wring out any excess moisture.

Gently wipe each key, starting from the top and moving to the bottom. Avoid applying excessive pressure or using too much water, as this may damage the keys or the internal electronics.

After cleaning, use a dry microfiber cloth to remove any excess moisture from the keys. Ensure they are completely dry before turning the piano back on or covering it. Moisture can damage the internal electronic components of the piano if not properly dried.
