Is Soda Blasting better than sand and garnet blasting?
Sand and garnet blasting removes contaminants by wearing away the contaminant. It is unavoidable that whilst doing this, the underlying substrate is also worn away to some degree. Depending on the substrate material and what it is being used for, it is often the case that the substrate is damaged. By contrast, Soda blasting 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. Soda blasting does not activate metal. By contrast, sand and garnet blasting does. Activating metal causes it to react to its surroundings. In the case of ferrous metals, they rust. The result is that ferrous metals that have been sand blasted will require immediate coating to prevent rusting. By contrast, metal that has been cleaned using Soda blasting will rust at a much reduced rate and can be coated days after blasting rather than hours. In the manufacturing of a metal object,
