Gentle Yet Effective Surface Cleaning

FWS offers premium-grade walnut shell media for dry blasting applications where surface integrity matters. Our product removes paint, rust, carbon, or grease without scratching or warping metal or composite substrates — making it ideal for aerospace, automotive, and marine industries.

Applications Across Industries

Commonly used for stripping castings, deburring molds, cleaning engines and turbines, and deflashing electronics. It also supports burn-out applications in grinding wheel and ceramic manufacturing by enhancing porosity.

Engineered for Consistency

Available in a wide range of mesh sizes from 4/6 to -325 mesh (3.35 mm to 35 micron), our blasting grades meet performance demands across fine-detail work and heavy-duty surface cleaning. FWS ensures reliable supply with consistent hardness (Mohs 4.5–5) and low moisture content.
