The Uses of a Wire Brush

What are the uses of a wire brush?

  1. Removing rust
  2. Removing old coating
  3. Preparation before welding
  4. Removing excess slag
  5. Deburring
  6. Cleaning
  7. Distressing wood

A wire brush is a type of tool that is mainly used for its abrasive properties. Most wire brushes are made with stiff metal bristles, but the material will depend on the type of application and work it is used for. In general, this type of tool is used for cleaning purposes, but there are other uses too — such as preparing metal surfaces or weathering certain materials. If you’re interested to learn the uses of a wire brush, keep on reading!


Removing Rust

Removing Rust

Wire brushes are well-known for their abrasive texture, although other wire brushes are less abrasive. The brush can cut into the surface of the material, which means that it can be used to remove rust. The abrasive force can dig into hard-to-reach places and also large surfaces. That’s why there are different sizes of wire brushes. 

The type of wire brush used will depend on the type of material or application. For instance, it’s recommended to use a brass filament wire brush to clean a stainless steel surface. It can protect the material from contamination and is also not as abrasive as carbon steel. 


Removing Old Coating

Wire brushes can also be used to remove an old coating, before applying a newer and more durable coating. This tool is often used by woodworkers to remove paint from wood materials. The brush can easily lift peeling paint off the solid base. To use a wire brush for paint removal, the brush is often coated with thinner or solvent. The advantage of using wire brushes is that they can get into tight corners and edges.


Preparation Before Welding

Because of their abrasive texture, wire brushes are an effective tool for welders. The brush can remove impurities on the surface of material prior to welding. Some of these may be rust, corrosion, coatings, oil, and grime. A wire brush is preferred by welders because it makes surface preparation quick and easy. 

When choosing wire brushes for pre-weld applications, keep in mind that certain metals will require specific brushes. For instance, aluminum materials require you to use a steel wired brush. 


Removing Excess Slag

A wire brush can also be used after welding to remove slag and spatter. A slag refers to the nonmetallic byproduct that is produced after certain types of welding processes. This can make the surface of the product rough and abrasive. It also affects the metal’s ability to bond with coatings too. That’s why removing slag is an important task for welders.

The stiff metal wires on a wire brush can easily remove slag without damaging the base material. The wires batter the slag, acting as miniature hammers, to loosen it from the metal surface.



Deburring refers to the removal of small imperfections from machined metal products. These imperfections are called burrs or ridges and protrusions in metal. Burrs can lessen the quality of the finished part if neglected.

Fortunately, wire brushes can deburr metal pieces to make the metal part smoother and of better quality. It’s a more economical way to remove burrs compared to using other methods and equipment.




A wire brush has metal bristles packed very closely, which is effective at cleaning the surface of a material. By using the brush, you can remove undesirable substances. But aside from removing rust and old coatings, a wire brush can also be used to clean off other substances too. 

For instance, a wire rotary brush can be used to remove stubborn oil, dirt, and grime from concrete surfaces. These are often attached to floor scrubbers. 


Distressing Wood

Distressing wood involves weathering it by hand to produce age and character in the material. It makes a wooden material have a more rustic aesthetic. While there are many techniques used to do this, using a wire brush is one of the easiest ways to do it. 

The wire brush you choose will depend on the effect you want to achieve. Usually, a handheld wire brush is used to create a soft sanded effect on the wood. There are also wire brushes with different grits available. 


Key Takeaway

Wire brushes are commonly used for cleaning up a material, whether it’s for surface preparation or getting rid of impurities from a finished product. Because of the abrasive texture of the brush, it can quickly remove any undesirable substance with ease.
