The offered services are rendered to several industries such as chemical, shipping, mechanical, automobile, etc. for cleaning and polishing metal surfaces.For etching and small object cleaning, a workstation to hold the piece of glass is also needed, as is some sort of collector to gather up excess dust. Sandblasting is primarily used for two somewhat different applications. The first of these is to clean a surface of anything that may be clinging to it. The second is to either etch or carve designs or words into glass or a similar material.
