For Sale: I have walnut cleaning / polishing media for sale at a discount price. This walnut is fine, 24 grit media, perfect for cleaning brass casings and jewelry in vibratory or tumbling cleaners. It can also be used in grit blasters for cleaning almost anything without harming surface finishes or sealing surfaces. I've got a considerable amount and will sell in 1 pound increments at a discounted cost of $2.00/pound. Shipping is available at an additional $5.80 S&H for up to 5 pounds.
