    This product is a little expensive, but it is the best media additive I have ever used. Worth the money.

    I've been using this product for years. It has no ammonia to damage brass and when used in conjunction with corn cobb media my brass looks like NEW MONEY when it's done. Highly recommended !!

    I have been using this product for YEARS !!! It's the best brass case cleaner I've ever used. Just add a little to your corn cob media and brass cases come out looking like new money. I can't say enough on what a great product this is. HIGHLY recommended.
