Walnut Shell & Corncob are soft blasting media, major advantage is that fragile components can be cleaned without marking or etching the components' blasted surfaces.

Walnut Shell is widely used for cleaning automobiles, moulds, motor armatures and motor drives prior to rewinding. Corncob is very light, soft and absorbent. It can be used for cleaning delicate surfaces or brass/brick/stone/wood, engines and engine components as well as mass finishing processes for drying and absorbing water, oil or wax from processed parts and also for fine polishing or brightening of parts.
