KAWAI
Use a soft duster for cleaning, avoid furniture polishes, tune 2–4 times per year, and have a Registered Piano Technician (RPT) perform regulation and voicing.
Cleaning: Use a soft feather or wool-type duster to remove dust. Avoid applying pressure or dragging dust across the finish — this can cause fine scratches that eventually dull a high-gloss finish. Fingerprints can be cleaned with a dampened soft cloth followed by a dry cloth. For stubborn greasy dirt, a small amount of mild dishwashing liquid or high-quality window cleaner (such as Windex) may help.
Furniture polishes are generally not recommended except for specialized high-gloss polishes. One recommended product is "Cory" Polish, available from Kawai America, your authorized dealer, and many piano technicians. If a high-gloss finish becomes dull or deeply scratched, a polyester repair specialist can restore it — contact your dealer for a referral.
The interior of the piano (plate, strings, soundboard, and action) should only be cleaned by a qualified piano technician. Improper cleaning may cause damage.
Tuning and Service: Kawai recommends 2–4 tunings per year, depending on temperature stability, humidity, and frequency of use. Pianos also need periodic regulation and voicing to maintain even touch and tone. If the touch seems uneven or notes do not repeat well, consult a technician.
For finding a qualified technician, Kawai recommends contacting a Registered Piano Technician (RPT) member of the Piano Technicians Guild. RPT members have demonstrated proficiency in piano tuning and servicing and maintain continuing education to keep their skills current.
