Understanding Rust and Why It Matters

Rust, or iron oxide, forms as a form of corrosion when ferrous metals like steel, iron, and cast iron react with oxygen and moisture. The process breaks down the surface, forming that familiar flaky coating. Rust removal is more than cosmetic - it protects metal parts, tools, and equipment from permanent damage. Salt, humidity, and pollution speed this up, especially on bare metal and heavily rusted items like garden tools or farm equipment.

Types of Rust Removers and Treatments

Rust Converter

Rust converters react with iron oxide and stop the corrosion process, forming a stable base for painting. Coo-Var V607/10 Rust Converter is acid free, making it suitable for most metals and safe to use on surrounding surfaces. Use it on vertical surfaces like railings, car bodies, or machinery.

Corrosive Inhibiting Primer

After treating rusted surfaces, it’s important to cover them properly with a sealant. Owatrol CIP Corrosive Inhibiting Primer sticks to metal, protecting against further corrosion and forming a solid base layer. It’s ideal for use on steel, aluminium, and copper components.

Zinc-Based Coating

For long-term protection on metal surfaces, use Zinga 96% Zinc Cathodic Protection. It delivers cathodic protection by forming a coating that sacrifices itself instead of your metal parts, especially useful on heavily rusted items and bare metal.

This zinc-based coating is compatible with various surfaces and does not harm existing paints or protective coatings.

Rust Penetrating Oil

Not every surface can be scrubbed or stripped. Owatrol Oil is non toxic and penetrates rust to stop further spread. It displaces trapped moisture and prepares the surface for paint, without harming plastic, rubber, or other materials nearby. Promain Owatrol Oil simplifies the rust removal process by eliminating the need for vigorous scrubbing, making it easier to treat rusted surfaces.

How to Remove Rust

Removing rust from metal surfaces can be a challenging task, but it can be done effectively with the right techniques and tools. The first step in removing rust is to clean the surface of any dirt, oil, or other substances that may be present. Use a wire brush to remove any loose rust and debris from the surface. For light rust, a rust remover or rust converter can be applied directly to the surface and left to sit for a specified amount of time. For more heavily rusted items, a more aggressive approach may be needed, such as sanding or using a drill with a wire brush attachment. When removing rust from vertical surfaces, it’s essential to take proper precautions to avoid damaging surrounding surfaces. Always wear protective gloves and eyewear when working with rust removers or other chemicals. Make sure to read and follow the instructions on the rust remover or converter carefully to ensure safe and effective use.

Benefits of Rust Removal

Removing rust from metal surfaces can help to prevent further corrosion and damage. Rust removal can also help to improve the appearance of metal surfaces, making them look like new again. By removing rust, you can help to extend the life of metal components and prevent costly repairs or replacements. Rust removal can also help to improve safety, as rusted components can be weak and prone to failure. In addition, removing rust can help to preserve the value of metal items, such as cars, farm equipment, and other machinery. Rust removal can also help to prevent the spread of rust to other areas, which can be costly and time-consuming to repair. 

By using a rust converter, you can convert rust into a stable, protective coating that prevents further corrosion. Regular rust removal can also help to prevent the need for more extensive repairs or replacements down the line.

Choosing the Right Rust Remover

When choosing a rust remover, it’s essential to consider the type of metal surface you’re working with. Different rust removers are designed for use on specific types of metals, such as ferrous metals, stainless steel, or aluminium. Consider the level of rust present, as some removers are better suited for light rust while others are more effective on heavily rusted items. Look for a rust remover that is non-toxic and acid-free to ensure safe use and minimal risk of damage to surrounding surfaces. Consider the ease of use and application, as some removers may require more effort or specialised equipment. 

Read reviews and follow instructions carefully to ensure you’re using the right product for your specific needs. Always follow proper safety precautions when using any rust remover, including wearing protective gloves and eyewear.



Safety Precautions

When working with rust removers or converters, it’s essential to take proper safety precautions to avoid injury or damage. Always wear protective gloves and eyewear to prevent skin and eye irritation. Make sure to read and follow the instructions on the product carefully, and take note of any warnings or cautions. Work in a well-ventilated area to avoid inhaling fumes or particles. Avoid using rust removers or converters on surfaces that are not intended for use, such as plastics or vinyl. 

Keep rust removers and converters out of reach of children and pets to avoid accidental ingestion or exposure. In case of skin or eye irritation, wash the affected area with soap and water and seek medical attention if necessary. Always follow proper disposal procedures for rust removers and converters, and take care to avoid environmental contamination.

Application Tips

  • Preparation is Key: Use a wire brush to remove loose rust, dirt, and flaky areas. For light rust, wiping with lemon juice can help loosen the iron oxide before applying treatment.

  • Wear Gloves and Take Precautions: Always wear gloves and work in a well-ventilated area. Some products release fumes during application - take proper precautions.

  • Follow Product Instructions: Whether you’re applying oil or soaking rusty tools, timing and curing are important for lasting protection.

  • Surface Type Matters: Be careful when working around plastic, brass, or painted areas. Use non toxic products like Owatrol Oil for delicate surfaces.

  • Use the Right Solution: Choose a chemical solution that effectively dissolves rust or converts it into a stable compound for long-lasting protection.

Rust Treatment for Common Uses

Marine & Outdoor Equipment

Boats and outdoor gear often suffer the worst from corrosion. Use Promain Zinga to coat metal with a zinc-based layer that resists water and salt. Apply CIP Primer before painting for long-lasting results.

Automotive Repair

On cars, treat rusted components like bolts or panels using Coo-Var Rust Converter. Follow it with CIP Primer to prepare for paint. Use Owatrol Oil around nuts, bolts, and joints where full removal isn’t possible.

Tools & Home Maintenance

Soak rusty tools in Owatrol Oil, wipe them clean, and apply a protective coat. For heavily rusted items, go with Zinga for total metal restoration.

Removing Rust from Vertical Surfaces

Removing rust from vertical surfaces can be more challenging than removing rust from horizontal surfaces. Use a wire brush or scrubber to remove any loose rust and debris from the surface. Apply a rust remover or converter to the surface, following the instructions carefully. Use a brush or cloth to apply the remover or converter, working from the bottom up to avoid drips and runs. Allow the remover or converter to sit for the specified amount of time, then rinse the surface with water. Use a clean cloth or brush to wipe away any remaining rust or debris. 

For heavily rusted items, you may need to repeat the process several times to achieve the desired results. Consider using a rust converter to convert rust into a stable, protective coating that prevents further corrosion and makes future maintenance easier.

Preventing Rust from Coming Back

  • Routine Cleaning: Scrape or wipe down tools after use, especially if exposed to water or soil.

  • Protective Coatings: Use CIP Primer or Zinga for bare metal and exposed steel.

  • Storage Matters: Keep equipment and tools dry, off the ground, and away from moisture to reduce long-term exposure.
