Thoroughly inspect your Barbecue grill for rust spots. Focus on common areas prone to corrosion. These can include cooking grates, burners, and exterior surfaces. Use a flashlight if necessary to examine hard-to-reach spots.

Overall, identifying the severity of rust corrosion helps you prioritise your efforts. It allows you to allocate more time and resources to heavily affected areas. At the same time, while taking preventive measures for those showing early signs of rust.

A thorough assessment sets the foundation for effective rust removal. This practice also ensures your efforts are targeted where they are most needed.

To tackle rust removal from your BBQ effectively, you must have the right tools and materials. Here are the essential items you’ll need:

  • Wire brushes. These brushes feature stiff bristles that are ideal for scrubbing away loose rust. They’re also effective for cleaning surface corrosion from metal surfaces.
  • Steel wool. This abrasive material is useful for removing stubborn rust. It also works wonders for smoothing out rough areas on your BBQ.
  • Sandpaper. Coarse-grit sandpaper helps in removing rust from hard-to-reach corners of your BBQ.
  • Rust remover solution. Helps dissolve rust and aids in loosening stubborn rust stains.
  • Gloves. To protect your hands from chemicals, sharp edges, and potential contaminants.
  • Protective gear. This includes goggles and a mask or respirator. Wearing them shields your eyes and respiratory system from debris, dust, and more.

Each of these tools and materials plays a vital role in rust removal. By having them on hand, you’ll be well-prepared to tackle rust removal effectively.

Before diving into rust removal, start with a clean surface. Follow these step-by-step instructions for effective cleaning:

  1. Remove all grates and accessories from the BBQ to access all areas properly.
  2. Scrape off any loose debris, such as food residue or ash, using a grill brush or scraper.
  3. Use a wire or grill brush to scrub the cooking grates, burners, and other metal surfaces. This removes grease, dirt, and loose rust particles.
  4. For stubborn grease or grime, mix a mild detergent with warm water. Use a sponge or cloth to scrub the surfaces thoroughly. Avoid harsh chemicals or abrasive cleaners that may damage the BBQ’s finish.
  5. Rinse all surfaces with clean water to remove any residue from the cleaning agents.
  6. Allow the BBQ to dry completely before proceeding with rust removal. You can use a clean towel or let it air dry naturally.

Wear protective gloves to shield your hands from chemicals and sharp edges. Ensure proper ventilation in the area to prevent inhalation of cleaning fumes.

The method you choose to remove rust from your BBQ depends on the severity of the corrosion and the type of surface you are dealing with. Here are different methods and techniques to consider:

Wire brushes, steel wool, or sandpaper

  • For light surface rust, start by using a wire brush to scrub the affected areas. Move the brush back and forth in a firm but controlled motion to remove loose rust particles.
  • If the rust persists, upgrade to steel wool or sandpaper. Use medium-grit steel wool or sandpaper to scrub the rusted areas gently. Do this in a circular motion until the rust is removed.
  • For more stubborn rust, switch to coarser-grit sandpaper. Make sure to apply more pressure while scrubbing. Be careful not to damage the underlying metal surface.

Rust remover solutions

  • Rust remover solutions can be effective for moderate to heavy rust. Apply the solution according to the manufacturer’s instructions using a sponge/brush.
  • Allow the solution to penetrate the rusted areas for the recommended amount of time. Ensure it doesn’t dry out.
  • Use a wire brush or steel wool to scrub the surface while rinsing with clean water.
  • Repeat the process if necessary until the desired level of rust removal is achieved.


By investing time and effort into rust removal, you can prolong the lifespan of your BBQ. Even better, you can continue to enjoy delicious grilled meals for many seasons to come.
