Description

Tackle tougher cleaning jobs with our premium 12–20 grit crushed walnut shell media. This coarse-grade natural abrasive is designed for more aggressive removal of paint, carbon buildup, grease, and heavy grime—while still protecting the underlying surface from damage. Ideal for blasting cabinets and vibratory tumblers, this larger grit size delivers faster stripping power and efficient cleaning across a wide range of materials. It works exceptionally well on metal, stone, wood, fiberglass, and durable plastics where a stronger cut is needed without the harshness of traditional abrasives. Made from natural walnut shells, this media is environmentally friendly, biodegradable, and 100% silica-free—offering a safer alternative for both users and equipment.

  • Worked for what I bought it for.
I was told by a quilting club to use this in pin cushions. I had never heard of it. (I'm a newbie I guess) WOrked great for the pin cushions I made.

Used for homemade heating pad. Holds the heat well and does smell when warmed up. Very happy with the outcome.

  • Walnut media is coarse enough to clean even the dirtiest brass.
The walnut media came well packaged. I have used it to clean old brass, ceramic figurines, and an assortment of painted tools.

  • Worked for cleaning my rifle brass
I was using ground corn cob to clean my brass, but it didn't work all that well. After switching to the walnut, my brass came much cleaner faster.

  • Shop around
Since I used to buy bulk walnut and cob for reloading, I rarely need to buy these products. Things have obviously changed. "Polishing" material added, polishing products that do not come close to the pure product.
