In 1972, when New York State engineers were looking for ways to clean the Statue
of Liberty, they had many concerns involving issues of the environment, waste disposal,
and protection of the statues surface itself. Any use of any abrasive material to
clean the surface would have been very harmful to the soft copper plates and would
have had environmental consequences for the water surrounding the statue.
Sodablasting was developed because it would not only do the job while having a negligible
impact on the waterways and harbour, it was also non-abrasive.
Just like the surface of the Statue of Liberty, this non abrasive action allows SodaBlasters
to be used on surfaces that current popular abrasive media would damage. i.e.: aluminium,
stainless steel, brick, stone, glass, fibreglass, wood, some plastics, seals, bearings,
splines, radiator cores, transmission cases, and hydraulic cylinders.
Sodablast particles remove contaminants by the energy released when the particles
'explode' as they come in contact with the surface to be cleaned. This results in
no damage to underlying substrates. By contrast, sand and grit blasting can damage
the underlying material.
Ferrous metals that have been sand blasted will require immediate coating to prevent
rusting. By contrast, metal that has been cleaned using Sodablast will rust at a
much reduced rate and can be coated several days after blasting rather than hours.
