How to Clean Mild Carbon Steel

Carbon steel is a popular material used in various applications, such as knives, tools, and construction materials. As with any metal, mild carbon steel needs to be properly cleaned to prevent corrosion and ensure that it lasts for many years. Here’s how to clean mild carbon steel the right way.

Remove Rust and Corrosion

The first step in cleaning mild carbon steel is to remove any rust or corrosion from the material’s surface. This can be done using a steel brush or cloth-wrapped sandpaper. Be sure to move along the grain of the material when brushing or sanding, as this will help to avoid scratches on the surface of your carbon steel item. Once the rust has been removed, use a damp cloth to wipe off any leftover dust or grit from the surface.

Cleaning Solutions

Once you have removed any rust or corrosion from your carbon steel item, it’s time to start cleaning it with an appropriate solution. Warm water with a mild detergent will do just fine for most applications. However, if your item is particularly dirty or stained, you may need something stronger—such as white vinegar or lemon juice—to get it clean and shiny again. Make sure you rinse off all residue after applying these solutions before moving on to the next step.

Polishing & Protection

After your mild carbon steel item has been thoroughly cleaned and dried, it’s time to polish it! A paste wax can be applied with a soft cloth to protect against future corrosion and give it a nice shine at the same time. If you want an extra layer of protection against rusting, consider applying a coat of mineral oil after waxing for maximum results.


Cleaning mild carbon steel doesn’t have to be complicated! With these simple steps—removing rust/corrosion, cleaning with an appropriate solution, polishing & protecting—you can easily keep your items looking new without damaging them. Whether restoring an old knife blade or simply trying to keep your tools looking their best, following these steps will ensure that your mild carbon items stay rust-free and look great for years to come!
