About this item

Fine Grit 18-40 Crushed Walnut Shells offer a powerful, all-natural solution for sand blasting, vibratory tumbling, polishing, and deburring. Sourced from 100% pure walnut shells and precisely graded to 0.42 mm–1 mm, this silica-free media is tough enough to strip paint, grease, carbon, and surface dirt, yet gentle enough to preserve delicate substrates. Use it confidently on soft metals, wood, plastic, fiberglass, glass, stone, jewelry, and gems without scratching or etching. The ideal media for soft metal cleaning, it cleans and polishes brass reloading casings to a brilliant finish without peening. It also tackles car engine carbon cleaning with ease β€” safely blasting away carbon buildup on valves, intake manifolds, and engine components without harming the metal. Beyond the workshop, it excels as an all-natural pincushion filler that keeps pins and needles sharp, clean, and rust free. Crafts enthusiasts love it for scale modelling, anti-slip coatings, and filler applications. With a Mohs hardness of 4.5–5, these walnut shells remove carbon buildup and surface deposits efficiently while protecting the underlying material. Completely non-toxic and reusable, this sustainable walnut media delivers professional results across countless automotive, workshop, and home projects.
