Refurbishment refers to the process of restoring or improving an item, typically by cleaning and repairing it. It can also involve updating or modernizing a product so that it appears new again. Refurbishment is often used in relation to electronic devices such as phones or laptops, where the device may be repaired, restored to its original condition, and then resold with a warranty. In general, refurbishment refers to any process of restoring something to its former glory, whether it's an item, a building, or even a piece of land.
