Bi-carb Soda is a relatively soft and friable media. Upon striking the work surface, the media crystals quickly disintegrate without damaging or distorting most substrates. Bi-carb Soda can be used to clean and depaint almost any substrate, including sensitive components such as hard anodized aluminium, composite plastics, ceramic tiles, stainless steel, glass and natural or synthetic rubber. In one simple step, carbon, grease, oil, graffiti and paint can be removed from delicate parts or stonework.
