The Statue of Liberty was one of the earliest beneficiaries of a cause marketing campaign. A 1983 promotion advertised that for each purchase made with an American Express card, American Express would contribute one penny to the renovation of the statue. The campaign generated contributions of $1.7 million to the Statue of Liberty restoration project. In 1984, the statue was closed so that a $62 million renovation could be performed for the statue's centennial. Chrysler chairman Lee Iacocca was appointed by President Reagan to head the commission overseeing the task (but was later dismissed "to avoid any question of conflict" of interest).[30] Workers erected scaffolding around the statue, obscuring it from public view until the rededication on July 3, 1986 — the scaffolding-clad statue can be seen in the 1984 film Desperately Seeking Susan, in the 1985 film Remo Williams: The Adventure Begins, and in the 1985 film Brewster's Millions. Inside work began with workers using liquid nitrogen to remove seven layers of paint applied to the interior of the copper skin over the decades. That left two layers of tar originally applied to plug leaks and prevent corrosion. Blasting with baking soda removed the tar without further damaging the copper. Larger holes in the copper skin had edges smoothed then mated with new copper patches.[citation needed]

Each of the 1,350 shaped iron ribs backing the skin had to be removed and replaced. The iron had experienced galvanic corrosion wherever it contacted the copper skin, losing up to 50% of its thickness. Bartholdi had anticipated the problem and used an asbestos/pitch combination to separate the metals, but the insulation had worn away decades before. New bars of stainless steel bent into matching shapes replaced the iron bars, with Teflon film separating them from the skin for further insulation and friction reduction.

The internal structure of the upraised right arm was reworked. The statue was erected with the arm offset 18" (0.46 m) to the right and forward of Eiffel's central frame, while the head was offset 24" (0.61 m) to the left, which had been compromising the framework. Theory held that Bartholdi made the modification without Eiffel's involvement after seeing the arm and head were too close. Engineers considered reinforcements made in 1932 insufficient and added diagonal bracing in 1984 and 1986 to make the arm structurally sound.

Besides the replacement of much of the internal iron with stainless steel and the structural reinforcement of the statue itself, the restoration of the mid-1980s also included the replacement of the original torch with a replica, replacing the original iron stairs with new stairs, installing a newer elevator within the pedestal, and upgrading climate control systems. The Statue of Liberty was reopened to the public on July 5, 1986.
