Rust Removal

Professional Methods used for Rust Removal

Rusting is a natural occurrence that involves the reaction of iron to form iron oxide. This process causes deterioration, contamination and loss of structures, especially those made of metal. Rust is also common in concrete surfaces as some stones contain rusting components. If signs of rusting are detected at an early stage, it is possible to prevent this prolonged corrosive action and, thus, its destructive effects.

Conditions that support rusting.

Water and oxygen -This is common to outdoor structures commonly exposed to humid air or flowing water. Any metal structure unless coated with anti-rust finishes will rust when exposed to damp conditions.

Presence of cracks- Rusting has been observed to occur first to inner parts of metal structures and then proceed to the outer surface. The internal parts provide a conducive environment to contain the above rust supporting factors. Cracks, therefore, provide a pathway for water and oxygen, enhancing rusting in structures.

Impurities- Did you know that pure iron in dry air will never rust? Rusting can only occur if the iron used to make your structures contain, other than the primary conditions, impurities such as acids and salts promote rusting.

Removing rust requires specialized equipment, chemicals or natural products and some level of expertise. It would then help if you left the work of removing this flaky brown coating on structures to professionals.

Methods used to remove rust professionally

Physical methods


This is a common physical method that involves removing the rust coat by the use of abrasive surfaces. Generally, powered metal discs are used to shave rust off surfaces. Sanders, whether electric or manual, are also used for this purpose. A valuable tip when using these tools is starting with the ones with smaller grit to remove most of the rust coating and proceed to the finer ones to finish the process and smoothen the surfaces.

Pressure washing

The use of high-pressure water has been proven to be effective in removing rust. This method is preferable for removing rust stains on extensive surfaces. The advantage of pressure washing has over scrapping is that it is less likely to cause compromise to the initial structures. A professional exterior cleaner must dry all the surfaces thoroughly after pressure washing, particularly if the climatic conditions do not support natural and fast drying.

Chemical methods

There is a wide variety of rust removal chemicals used by professional outdoor cleaners. All these chemicals are tailored to react with rust creating a material that is easier to remove. Other than industrially processed rust removers, chemicals such as oxalic acid, citric acid and baking soda are also used to remove rust. Since some of these chemicals are strong and abrasive to the skin, professionals use protective clothing and follow safety measures when using the chemicals.

Seeking professional services on rust removal will not only save you on money by not buying all these tools, gears and chemicals but also on time required to remove the rust residue, especially from large commercial structures. Professional rust removal eliminates the displeasing look that rusted surfaces have and leaves your structures as good as brand new!
