area after completely coating it with salt. Use as much lime juice as possible and leave it to sit for 2 to 3 hours before cleaning away the combination.

Manual Rust Removal

You can use iron sandpaper, a scraper, a spatula, a wire brush for rust removal, and other hand tools. This method is labor-intensive and has a poor production efficiency, but it is simple and adaptable to use, and it is still in use today.

For those raw extruded or cast metals such as aluminum and stainless steel, grinding is a critical first step in achieving a mirror polishing. You can use wire cup wheel or angle grinder flap disc to remove rust. If you’re using relatively smooth metal, you probably don’t need to sand. Remember that sanding never makes it shinier, but it can save you time and make the surface flatter.

High-Pressure Water Rust Removal

Using water as the medium, high pressure is generated by the high-pressure producing device and immediately expelled from the nozzle; the water jet produces a highly concentrated energy that strikes and grinds the cleaned metal surface like a water arrow. The ultra-high pressure water jet is inserted as a wedge between the scale layer and the metal surface, removing oxide scale, old coating, and other contaminants from the workpiece’s surface, as well as very hard corrosion products. When the abrasive is mixed into the water, the action is enhanced.
