Cleaning used pianos requires following certain steps and precautions to ensure the piano's appearance and performance are maintained.

Prepare Tools: Gather soft cloths, cotton swabs, a vacuum cleaner, and cleaning agents, ensuring they are clean and free of debris.

Clean Keyboards: Gently wipe the surface of the keys with a soft cloth or cotton swab, ensuring not to use overly damp cloths or excess water to avoid damaging the keys. Additionally, regularly use a keyboard care product to maintain the luster and texture of the keys.

Clean the exterior: Wipe the piano's exterior with a soft cloth, including the legs, body, and lid, being careful to avoid using abrasive fabrics or scratching the surface. If necessary, use a small amount of furniture cleaner, but avoid any with strong odors.

Clean the Pedals: Wipe the pedals and pedal axles with a vacuum or a soft cloth to ensure they are clean and free of dust.

Clean Inside: If the piano's top can be opened, use a vacuum or a soft cloth to clean the dust and debris inside. Be cautious not to go too deep inside to avoid damaging the internal components.

Keep Dry: After cleaning, make sure to place the piano in a dry environment, avoiding moisture and water to prevent damage to the wood and metal components.

Regular Cleaning: It is recommended to clean pianos regularly, with a complete cleaning and maintenance at least once a year to ensure the piano remains in good condition and performance.
