Grit-O'Cobs®: Resilient, durable corncob granules
that blast-clean complicated jobs.

Grit-O'Cobs® granules are increasingly the choice when the
job calls for a softer, less dusty and environmentally safe
abrasive. While sand remains the most widely used abrasive,
successful abrasive cleaning still depends heavily upon the
selection of the proper abrasive for each job.
The acceptance of Grit-O'Cobs® granules stems from many
beneficial characteristics. They are hard, yet soft. They are
cleaner and less dusty than many other abrasives. They are
also biodegradable. In addition, Grit-O'Cobs® can also be
used in most standard sandblasting equipment. They are
non-sparking and will not damage the gears of operating
equipment as sand often can.
Log Home Blast Cleaning with Grit-O'Cobs®
(photos on cover)
The soft grit abrasive cleaning power of Grit-O'Cobs® can be
used to blast-clean a log home that has a residue buildup
from many years of weather’s wear and tear.
The natural benefits are: it’s biodegradable, is less abrasive
and harmful than sand blasting, and because of its low bulk
density, you need fewer pounds of Grit-O'Cobs® to complete
most jobs.
The natural cell structure makes the Grit-O'Cobs® granules
highly absorbent. The granules can therefore absorb the
substance to be removed, thereby helping speed up and
intensify the cleaning process.
