In addition, high RH will promote the oxidation of metal elements such as tacks and springs in furniture. This will not only deteriorate the metal itself but will stain and embrittle the fabrics and stuffing that it contacts. Light Light damage is cumulative and irreversible. Some upholstery fabrics, such as silk, are particularly susceptible to light damage. Light will also fade wood stains and the natural color of the wood as well as degrade wood finishes.
Sunlight contains both the visible and UV components of the spectrum.
Therefore, do not display upholstered furniture in direct sunlight. It is advisable that upholstered furniture be totally protected from light when it is not being viewed. This can be accomplished by shutting light off at the source or covering the object with clean cotton sheets. Dust and Dirt Dust particles which generally include lint as well as organic debris act as an attractant and food source for insects and attract moisture to the surface of the object. In addition dust is abrasive and over time can damage the finish of exposed wood members.
