Lighting - Like most sculpture, furniture does require that it gets proper lighting, in order to give the full effect. If you think about a sculpture in an art museum, they are very careful about the lighting they use, to make sure it will show off the best features of the piece. Care should be given to ensure that you have lighting set up that can show off your furniture's best features.
Cleaning - Cleaning the furniture can be completed with regular soap and water. It is important to not allow water to sit on the surface for an extended period of time.
Refresh - Furniture Polish should not be used, because it's very tough to clean off, and would interfere with any repairs that need to be made in the future. A better solution would be a furniture paste wax. Wax will refresh the wood finish and it's able to be cleaned off, if needed for a future repair.
Repairs - Please email me a picture of any damages that might happen to the piece and I can give advise on how to repair it.
