- Generally speaking, a soft disposable towel, using warm water and hand/dish soap is safe to use on virtually every finish, key, and case part. Always follow up with a dry soft disposable towel to dry any standing liquid.
- Cleaning pianos is a gentle process not a scrubbing process. Pressing hard or vigorous scrubbing may lead to scratching or removing the finish. Always proceed with caution and use common sense. Remember to wash your hands after you have thrown away the towels.
