How to Sand Rust Off Metal: A Step-by-Step Guide

Wondering How to Sand Rust Off Metal? If you have a metal object that has been left outside for too long, you may notice that it has developed rust. Rust can not only be unsightly, but it can also weaken the metal over time. Fortunately, with some sandpaper and elbow grease, you can easily remove rust from metal surfaces. In this guide, we’ll walk you through the steps to effectively sand rust off metal.

Step 1: Gather Supplies

Before you start sanding, you’ll need to gather the necessary supplies. This includes:

Safety goggles and gloves
Sanding sponge (coarse, medium, and fine-grit)
Wire brush or steel wool
Clean rags or towels
Rust converter (optional)
Paint or primer (if you plan to repaint the metal)

Step 2: Prep the Area

Before you begin sanding, you should prepare the area to protect yourself and your surroundings. Put on safety goggles and gloves to protect your eyes and skin from debris and rust particles. Lay down a tarp or drop cloth to catch any dust or rust flakes that may fall during the sanding process.

Step 3: Remove Loose Rust with a Wire Brush or Steel Wool

Using a wire brush or steel wool, gently remove any loose rust or debris from the surface of the metal. This will make it easier to sand the remaining rust off.

Step 4: Sand Rust Off Metal surfaces

Starting with coarse-grit sandpaper, begin sanding the surface of the metal. Use a circular motion to remove the remaining rust, being careful not to apply too much pressure or damage the metal. Once you’ve removed most of the rust with the coarse-grit sandpaper, switch to medium-grit sandpaper to smooth out any rough areas. Finish with fine-grit sandpaper to create a smooth, polished surface.

Step 5: Wipe the Surface Clean

Using a clean rag or towel, wipe the surface of the metal to remove any dust or debris left behind from sanding. If you plan to repaint the metal, it’s important to remove all the rust and debris to ensure a smooth, even coat of paint.

Step 6: Apply Rust Converter (Optional)

If you want to prevent future rust from forming on the metal surface, you can apply a rust converter. This product chemically converts any remaining rust into a more stable compound, protecting the metal from further corrosion. Follow the instructions on the rust converter product carefully to ensure proper application.

Step 7: Repaint (Optional)

If you plan to repaint the metal, be sure to apply a coat of primer first to ensure the paint adheres properly. Once the primer has dried, apply a coat of paint in your desired color.


Sanding rust off metal is a simple process that can restore your metal objects to their former glory. By following the steps above, you can effectively remove rust from your metal surfaces and prevent further corrosion. Don’t forget to take safety precautions and wear protective gear while sanding, and consider using a rust converter or repainting the metal for added protection. With some elbow grease and the right supplies, you can easily sand rust off metal and enjoy your restored objects for years to come. Find our best sander for rust removal here.
