Walnut Shell Abrasive - Walnut Shell Media Blasting Abrasive

The Walnut Shell blasting abrasive is a biodegradable plant-based abrasive made from crushed fruit pits, without any chemical additives. The use of this low-hardness abrasive (3.5 on the Mohs scale) allows for selective layer stripping without altering the substrate. Walnut shell is used for cleaning aluminum parts and engines or other metal surfaces, without changing their surface condition. This abrasive is also used to remove paint layers from aerospace components and is ideal for graffiti removal.
