Lou Cella, the Chicago artist who created the Banks statue, said Cubs officials wanted the statue restored because it was "oxidizing a little too fast" and was "turning green," the Peoria (Ill.) Journal Star reported Thursday.
Cella said he enlisted the help of Kyle Chipman, who worked with him on a statue of Cubs great Ron Santo, for the restoration.
Chipman said the statue was taken to Bradley University in Peoria Nov. 2 and the old finish was burned off with a torch. He then sandblasted the surface and cleaned it with a metal degreaser.
Chemicals were applied to the statue to give it a new surface appearance and a coat of lacquer was applied.
Chipman said the statue of the 80-year-old hall of fame shortstop and first baseman will return home to Wrigley Field Friday.
