Refurbish

v. make new again, renovate, restore to good condition

Refurbishment (restoration) is the process of major maintenance or minor repair of an item, either aesthetically or mechanically.Often, antiques such as furniture are refurbished to bring back their original luster by applying new paint or wood stain, fixing loose joints with glue or nails, and cleaning or replacing hardware such as drawer pulls.Toys such as model trains are also refurbished, especially if they are considered classics. In some cases, even paper items such as valuable comic books can be refurbished by replacing rusty staples, removing page stains with chemicals, etc.
