Art Restoration
Napa Valley, San Francisco North Bay, Ca. USA

Art Restoration or Art conservation can involve the cleaning and stabilization of art work. Ideally, any process used is reversible, departures from that ideal not being undertaken lightly. Cleaning is not a reversible process and can sometimes be controversial due to fears that cleaning would damage a piece, or on the grounds that damage or residue forms part of the history of a given piece and should not be modified. Michaelangelo's statue of David has undergone two cleanings to remove dirt that had accumulated on the statue's surface.
