Each piece of Norngaard indoor furniture goes through a multi step treatment process prior to shipping to ensure it will hold up to everyday wear and tear in your home. There are however several things you can do to care for your furniture so it can be enjoyed for many years to come. 1. Do not scrape furniture with sharp objects. - All Norngaard furniture is finished with multiple coats of a non toxic, water based protective sealant to protect the wood for every day use. However, this does not mean the sealant is impenetrable: deep dents and scratches may cut through the sealant and damage the wood. 2. Do use coasters for beverages when possible, and clean up any spills when they happen. -The protective sealant will ensure water does not permeate to the wood, however it is good practice to ensure liquids are not sitting on your furniture for extended periods of time. 3. Clean your furniture with a damp cloth or any non abrasive furniture polish/cleaner. 4. Do not use indoor furniture for outdoor use for extended periods of time. -Direct exposure to harsh elements such as direct sunlight, rain, or fluctuation of temperatures will cause the wood to warp or split. We at Norngaard take great care to seal our outdoor furniture with a weatherproof, UV resistant sealant to prevent such damage, but our indoor furniture is not equipped with this sealant. -We do NOT recommend using harsh household chemicals as they can damage the finish.
