dehumidifies by 3 key wood drying principles
constant heat supply
The KILN supplies constant heat to your guitar soundbox. The gradual heat gently heats up the air within your guitar soundbox throughout the entire dehumidification process.
The constant heating keeps the air within the guitar warm. The warm air would greater capacity to absorb moisture from your guitar.
Heat transfer through convection takes place naturally thus air saturated with moisture will be replaced by dryer air. No removal of guitar strings, just place your guitar in a well ventilated space for such air circulation to take place.
