(High efficiency, energy saving, non-toxic, no heavy metal)

       1. Remove the welding spots, rust spots, and yellow, blue, black welding spots and other contaminants of various types of austenitic stainless steel workpieces after welding. Not only does not change the natural color of stainless steel, but also can greatly improve the salt spray resistance time. It is a substitute for the color change of the workpiece caused by the traditional pickling solution. It is free of chromium and does not contain hexavalent chromium components such as chromate. Excellent resistance to salt spray corrosion, the highest has passed the NSS neutral salt spray test 500H

       2. Simple operation, convenient use, economical and practical; especially suitable for small complex workpieces.

       3. After treatment, the workpiece is clean and refreshing, achieving the effect of the natural color of stainless steel, without changing the original color and luster, and having a strong decorative effect.

       4. It does not contain harmful ingredients, the pH value is acidic, it is non-irritating to the skin, provides excellent cleaning performance, and protects the health of users. In addition, the treated waste liquid only needs to be neutralized and discharged directly, thus achieving zero pollution to the environment.
