Introduction and Meaning

Corncob is the fibrous core of the corn ear, dried and processed to create a versatile and high-performing product. Mainly used for polishing and drying metal surfaces without leaving stains or halos, it finds applications both in the catering industry and various industrial sectors. Its granulation can vary, adapting to different professional needs.


Technical Features and Differences

Corncob is characterized by its natural absorption properties and delicacy. The lightweight, porous fiber allows for cleaning, polishing, and drying surfaces without scratching them. The main difference between types lies in the granulation, meaning the size of the particles, which can be fine, medium, or coarse depending on usage requirements.

  • Fine Granulation: ideal for delicate polishing on fine surfaces such as catering cutlery.
  • Medium Granulation: excellent for quick drying and cleaning of industrial metal tools.
  • Coarse Granulation: used in technical sectors for removing larger residues or intensive drying.
