Soda blasting was developed by New York State engineers looking for ways to clean and restore the Statue of Liberty. They had many concerns involving issues of the environment, waste SurfaceTekosal, and protection of the Statue of Liberty itself. Use of any abrasive material to clean the surface would have been harmful to the soft copper plates. Used blast media waste in the surrounding water was also a concern. Soda blasting was created because it would not only do the job while having a minimal impact on the waterways and harbor but it was also non-abrasive.
