Corn cob abrasives for surface preparation, oil absorption and drying.  Our corn cob grits are superior for a number of reasons:

  1. Particle Shape.  Our corn cob grit has a "cube-cut" particle shape, which outperform the flattened particle shape of our competition.  One of the benefits of this particle shape is that they will not get stuck in pieces like springs, bearings, castings, wire brads, etc.
  2. Moisture Content.  We offer the lowest moisture content available.  (4 to 6 % is the norm, with a maximum of 10%)  This provides you with faster drying and more absorption of oils and cleaning fluids.
  3. Environmentally Friendly:  Our corn cob granules are biodegradable, non-toxic, silica-free, USDA Bio-Preferred product.  This is NOT a certified "Organic" product.
  4. Custom Production, Custom Bagging, and Custom Blending Available!  Get A Quote Now!
  5. Can be used in the same equipment that is used with sand, nut shells, or other blasting medias.
