Product Details
✓COARSE 12/20 GRIT FOR BLASTING & CARBON CLEANING – The heavy cutting size for walnut blasters, cabinet blasting and intake valve carbon removal on BMW, VW, Audi and other direct-injection engines. Strips carbon, paint and scale fast without harming aluminum heads.
✓CALIFORNIA ENGLISH WALNUT, SCREENED & PACKED IN THE USA – Sourced from California English walnut shell, screened to a consistent 12/20 mesh and bottled at our facility in Griffith, Indiana. Not imported, not blended. Low dust, uniform grain, batch after batch.
✓SAFE ON DELICATE SURFACES – Walnut shell is a soft, biodegradable abrasive (3–4 Mohs) that cleans aluminum, brass, chrome, wood, fiberglass and engine parts without pitting or warping. Ideal for intake valve carbon cleaning, gun parts, tumbling and vintage restoration.
✓REUSABLE MEDIA THAT LASTS – Recycles through a blast cabinet or tumbler many times before breaking down. 5 lb is a full charge for most benchtop vibratory tumblers (Lyman, Frankford Arsenal, Hornady) with plenty left for the next swap, or enough to run a benchtop blast cabinet for light-duty work. Add a capful of polish for mirror-bright brass.
✓RESEALABLE WIDE-MOUTH JAR – Ships in a heavy PET jar with a screw cap so it stores dry and pours clean. Need a different grit? We also offer 12/20 Coarse, 35/60 Fine and 40/100 Extra Fine, plus 15 lb bulk boxes — see the size selector above. Questions? We're a blasting shop; ask us.
