How to Polish Mild Steel?

Mild steel is one of the most popular metals used in everyday products and structures. It’s easy to work with, relatively inexpensive and can be polished or painted for a variety of applications. But polishing mild steel correctly can be tricky—it’s important to know the right products and techniques for the best results. Here are some tips on how to properly polish mild steel.

Start With Sandpaper

Before you begin polishing your mild steel, it’s important that you start with sandpaper. Start with coarse-grit sandpaper (150-220), then move up the scale to the finer grit (320-400). This will help remove any imperfections like scratches or rust from your metal surface, leaving you with a smooth surface that you can polish. Be sure to use light pressure while sanding and wear protective gear such as gloves and goggles if necessary.

Use Buffing Compounds

Once your mild steel has been thoroughly sanded, it’s time to apply buffing compounds. It’s important to choose the correct buffing compound for the job; there are different compounds designed for different types of surfaces, so make sure you pick one that is suited for polishing mild steel. You’ll also need an appropriate buffer wheel, such as cotton buffs or wool buffs; these will help ensure that you get even results when polishing your metal surface. When applying the buffing compound, make sure that you follow the manufacturer’s instructions carefully and apply it evenly across the entire surface.

Polish Your Metal Surface

Turn on your buffer wheel and slowly move it across your metal surface in overlapping circles until all of the buffing compounds have been removed from your metal surface. You should see a shining beginning to appear as you work; keep working until all of your metal has been polished evenly throughout its entire surface. Once you’re done, turn off the buffer wheel and inspect your work; if any spots appear duller than others, simply repeat this process until all spots have been polished evenly over the entire surface of your metal piece. Finally, wipe off any residual dust or particles from your metal piece before moving on to another project!


Polishing mild steel can seem intimidating at first glance, but following these steps will make it easy! Just remember to start with sandpaper for prep work and use buffing compounds tailored for polishing mild steel, along with an appropriate buffer wheel for optimal results! With patience and practice, soon enough, you’ll be able to easily polish any type of mild steel without breaking a sweat! Plus, having shiny new pieces around always looks great too! Good luck!
