How to Remove Rust from Garage Door

In the coastal charm of the Northern Beaches of Sydney, rust on garage doors is a common headache—the salty air and humidity team up to create a stubborn foe for homeowners.

This garage door guide will cut through the clutter and share straightforward, homemade solutions to tackle rust head-on and keep your garage door looking sharp against the coastal elements.

DIY Rust Removal Techniques

Rust on your garage door can look bad and cause problems. Below, we have shared easy DIY ways to get rid of rust on garage doors using everyday household items.

Vinegar and Baking Soda Solution

  1. Prepare Surface: Clear debris and wipe down the rusted area with a dry cloth.
  2. Create Paste: Mix white vinegar and baking soda in a bowl to form a thick paste.
  3. Apply Paste: Use an old toothbrush or wire brush to apply the paste directly onto the rusted areas.
  4. Scrub: Vigorously scrub the rusted areas with the brush in circular or back-and-forth motions.
  5. Wait: Let the paste sit for 15-20 minutes to break down the rust.
  6. Wipe and Inspect: Use a clean cloth to remove the residue, inspect the treated area, and repeat if necessary. Consider applying a rust-resistant coating for prevention.

Lemon and Salt Scrub

  1. Gather Materials: Get a lemon and table salt from your kitchen. Ensure the lemon is fresh and the salt is coarse.
  2. Cut the Lemon: Slice the lemon in half. Use one half for the scrub and save the other for later use.
  3. Sprinkle Salt: Generously sprinkle salt on the cut surface of the lemon. The salt acts as an abrasive element to aid in rust removal.
  4. Rub the Rusty Areas: Take the lemon half with salt and rub it directly onto the rusty spots on your garage door. Apply pressure as needed to work the mixture into the rust.
  5. Let it Sit: Allow the lemon and salt mixture to sit on the rusted areas for 10-15 minutes. This gives the natural acidity of the lemon and the abrasive salt time to break down and lift the rust.
  6. Scrub and Rinse: Use a brush or scouring pad to scrub the rusted areas vigorously. Rinse with water to remove the lemon-salt residue and inspect the results. Repeat if necessary until the rust is sufficiently removed.

DIY Rust Dissolver Spray

  1. Gather Materials: Collect white vinegar, a spray bottle, and a wire brush. Ensure the area is well-ventilated.
  2. Clean the Surface: Use the wire brush to remove loose rust and dirt from the affected area on your garage door.
  3. Fill the Spray Bottle: Pour undiluted white vinegar into the spray bottle, ensuring it’s adequately filled for application.
  4. Apply the Solution: Generously spray the white vinegar directly onto the rusted spots on your garage door. Ensure complete coverage.
  5. Let It Sit: Allow the vinegar solution to sit on the rusted areas for 15-20 minutes. This gives it time to break down the rust.
  6. Scrub and Wipe: Use the wire brush to remove the loosened rust. Wipe the area clean with a rag, and repeat the process if necessary until the rust is gone.

How to Avoid Rust on Garage Door?

To avoid rust on your garage door, Opt for materials such as aluminium or stainless steel when installing or replacing your garage door.

These materials naturally resist rust, offering a longer lifespan in coastal environments where salt and humidity can accelerate corrosion.

Check out our guide on the Best Garage Door Materials for Coastal Homes for an in-depth guide on selecting the most suitable material.

Implement a regular cleaning schedule for your garage door, focusing on removing salt residue and dirt. Use a soft brush or cloth to wash the door with mild soap and water.

Please inspect for any signs of rust and address them promptly with appropriate rust prevention methods.

Apply a rust-resistant primer and paint designed for metal surfaces to create a protective barrier on your garage door.

Additionally, consider using a silicone-based sealant to fill any cracks or gaps, preventing moisture and salt from reaching the metal surface and initiating rust formation.

These measures act as a proactive shield against the harsh coastal elements.


Combating rust on garage doors in coastal areas like Sydney’s northern beaches demands a practical approach. The provided DIY techniques offer effective and affordable solutions, ensuring your garage door remains resilient against the corrosive effects of salty air and humidity.

Additionally, adopting rust-resistant materials during installation and following a consistent maintenance routine can significantly prolong the lifespan of your garage door, keeping it in optimal condition amidst the challenges posed by the coastal elements.

If DIY methods prove insufficient or rust issues persist despite your efforts, it might be time to seek professional assistance. Consider calling in experts when rust damage is extensive, affecting structural integrity, or if you encounter difficulties in the removal process.

Professional intervention becomes crucial when the corrosion has spread significantly, and the expertise of a specialist is needed to assess and address the situation effectively.
