How To Use Walnut Shells For Rust Removal?

Rust. There is no four letter word in the English language that brings with it such a level of concern or consternation. Not only is rust detrimental to the appearance of everything from vehicles to patio furniture, it can be hazardous to mechanical components such as engines, axles, and transmissions which can leak, freeze up, and fall apart as they rust out. Fortunately, removing rest is something that crushed walnut shells can help you accomplish in an eco-friendly and cost-efficient manner.

Crushed walnut shells are sufficiently hard enough
to remove rust from the surface of metal without
damaging the intact metal beneath.

Crushed walnut shells are sufficiently hard enough (MOH 3.5) to remove rust from the surface of metal without damaging the intact metal beneath. This makes it ideal for removing surface rust for painting or refinishing, as well as for preparing large holes for welding or other repairs.

To utilize in blasting, the walnut shells simply need to be added into the hopper of your abrasive blaster. There is no other special equipment or preparation required. Depending on the size of the material you are working on, you can easily adjust the grit size and the stream speed to suit your needs perfectly. Further, crushed walnut shells can be used within tumblers and other polishing devices to remove rust from nuts, bolts, screws, and other small and hard to handle objects.

Furthermore, because walnut shells do not absorb moisture, they can be used and reused many times before they need replaced. Their multi-faceted surface means they maintain effectiveness longer, and because they are non-toxic you don’t need any specialized operating equipment or clean-up procedures. For businesses seeking to “green up” their operations, crushed walnut shells provide a cost-effective and eco-friendly solution. As long as you remove the rust and other debris from within the grit pile, there will be absolutely no loss of effectiveness or eco-friendly benefits from the repeated use of the shells.
