Our metal polishing paste is carefully formulated with calcium carbonate and deionized water. Designed specifically to help clean oil stains and dust residues on metal surfaces. The usage method is extremely convenient: Take an appropriate amount of this product with a sponge and evenly apply it to the metal surface. Gently wipe in a circular motion until the surface regains its luster. Before the product is completely dry， thoroughly wipe off the residue with a clean and soft towel until the surface is clean and shiny. And it can quickly remove the dullness on the metal surface， restore the clear mirror-like texture， effectively block air and moisture， and slow down the oxidation rate of the metal.
