Our car rust removal spray contains citric acid, sodium carbonate, and disodium EDTA. It can quickly react with rust on the metal surface, effectively remove the rust layer, restore the smoothness of the metal surface, and form a solid protective film on the metal surface, effectively isolating air and moisture, preventing the metal from rusting again, and extending its service life. Its usage is very simple: clean and dry the area that needs rust removal, spray it directly on the rusted area, let the spray soak into the rusted area, wipe the surface clean, and repeat until all the rust is removed. It can remove rust efficiently, quickly restore the metal luster, provide lasting protection against future corrosion, enhance metal durability, and extend its service life. 30ml/box Car Rust Removal Spray Remove Car Rust Content: 52g Ingredients: Citric Acid, Sodium Carbonate, Disodium EDTA
