Tropical hardwoods, such as teak and eucalyptus, are naturally weather resistant due to their high oil content. This makes pieces easy to look after, as you can keep them outside throughout the seasons. It’s important to remember that these hardwoods can develop cracks along the grain after they've been exposed to the elements. Over time, teak will weather to a beautiful silvery grey colour. It's a natural timber so variations in colour and markings will occur from piece to piece.nnTo care for your furniture give your hardwood furniture a yearly scrub with soapy water, followed by a thorough rinse. This removes algae and pollution to restore the timber's surface, keeping it in good condition. If you want your teak furniture to look less weathered, restore some of the original colour by applying cleaner, followed by brightener and finished off with oil. Make sure the timber is completely dry when you apply the oil, otherwise it can blacken.
