Hydroblasting uses a stream of water to clean and polish the parts being processed. A fine glass media is used with the water to flow over the surface of the item and results in a much smoother finish than the dry blasting process. Filtered water in a closed system is used along with a rust inhibitor. It removes dirt, tarnish and oxidisation in a non destructive way and gently peens the surface to close the pores of the metal. The result is a satin polished look sometimes better than original finish which is resistant to dirt, fingerprints and tarnishing.
