Then when you can see that the rust has started to reduce, you need to sand, scrape, and brush off the surface regularly until all the rust is completely removed.

Step 4: Start the Rust Removing Process

After successfully finishing all the above processes, start your grinder slowly, and rise applying from one side of the rusted metal surface.
