Although sunlight is a rich source of vitamin D for our bodies, the same wreaks havoc on leather furniture. Prolonged exposure to sunlight not only causes discolouration, but it can also dry out your leather furniture—both of which are less than ideal scenarios that degrade the value and appeal of leather.
How Sunlight Discolours and Dries Leather
As you may already be aware, sunlight contains harmful ultraviolet (UV) rays, the same form of radiation that can cause the formation of cancerous skin cells. UV rays are inherently powerful, and are capable of causing disturbances at a molecular level. In fact, UV light can damage leather furniture in as little as four to six months.
First, UV light is able to change the structure of leather in the form of discolouration. You’ll notice that the once dark and neutral colour of your leather furniture will gradually turn to white. The effects of UV light doesn’t end there. As your leather furniture remains exposed to UV light, it begins to evaporate moisture from the leather, making it feeling dry and weak.
Protecting Leather Furniture from Sun Damage
Fortunately, there are ways you can prevent your leather furniture from discolouration and drying, the most important of which is to keep them as far from sunlight as possible. If you can’t find a spot that’s secluded from sunlight, make do with shades, blinds, window films, or other window treatments to help block out sunlight.
More importantly, have your furniture cleaned by leather cleaning professionals. Regular cleaning and conditioning can restore leather and help it better resist UV damage.
