Scouring sand in brick form

Scouring sand is a mild abrasive powder used to clean and polish hard materials such as metal or stone. This powder can also be moistened with water for use on a cloth for polishing or as a kind of sand paper.

Scouring sand usually comes in brick form for shipping and sale. Powder is scraped from the brick as needed, or the brick itself is wetted and used to scour.
