The kalimba requires proper care to prevent damage from dryness or humidity. Maintain appropriate humidity, avoid direct sunlight, and clean the keys regularly to prevent rust.
Details
During dry winter months, take extra care of your kalimba by storing it in a case or bag and maintaining an appropriate humidity level (30-60% RH). Consider using a humidifier to prevent the body from warping or cracking.
Regular playing helps maintain the wood's dryness, preventing the keys from absorbing moisture and affecting sound quality. If you won't be using the kalimba for an extended period, apply anti-rust oil to the keys.
Avoid exposing the kalimba to direct sunlight (if performing outdoors or in sunlight, store it away immediately after). After each use, clean the keys with a soft, clean cloth or towel to remove sweat and fingerprints, preventing rust.
In humid climates, it is recommended to store the kalimba in a plastic bag to avoid moisture and rusting keys. In such climates, perform maintenance at least once a week.
