From choosing corrosion-resistant materials to applying protective coatings, learn how door repair services can help ensure the longevity and performance of your valuable investments in this blog!

Commercial doors are crucial to any business, providing security, accessibility, and aesthetics. However, exposure to the elements and constant use can lead to rust, compromising both the functionality and appearance of these doors. This blog post will discuss practical rust prevention strategies to prolong the usefulness and longevity of commercial doors.

Let’s explore some rust prevention tips!

1. Understanding Rust

Iron oxide, commonly known as rust, forms when iron or steel reacts with oxygen and moisture. Commercial doors, especially those exposed to outdoor elements, are susceptible to rust. Preventing rust not only preserves the door’s appearance but also ensures smooth operation and prolongs its lifespan.

2. Choose Corrosion-Resistant Materials

One of the most effective strategies to avoid rust is to choose business doors made of corrosion-resistant materials. Aluminum and stainless steel are popular materials because of their inherent rust resistance. These materials are not only long-lasting, but also low-maintenance.

3. Regular Cleaning

Cleaning the door on a regular basis is necessary to prevent the accumulation of dirt, salt, and other corrosive elements on the surface. Use a mild detergent or a mixture of water and vinegar to clean the door thoroughly. Pay attention to corners, crevices, and other hard-to-reach areas where moisture and debris accumulate.

4. Apply a Protective Coating

Applying a protective coating is a proactive measure to prevent rust. Consider using a high-quality, weather-resistant paint or a specialized metal coating that forms a barrier against moisture and oxygen. Ensure that the coating is specifically designed for the material of your commercial door.

5. Implement a Maintenance Schedule

Regular maintenance, such as RCI Doors™’ SafeDoorPM, is crucial for preventing rust. Inspect your commercial doors at least twice a year, paying attention to hinges, handles, and other moving parts. Lubricate moving components with a rust-inhibiting lubricant to reduce friction and prevent rust formation.

6. Install Door Seals

Door seals enhance energy efficiency and act as an additional barrier against moisture. Adequately installed door seals prevent water infiltration, reducing the risk of rust formation. Regularly inspect and replace damaged or worn-out seals to maintain their effectiveness.

7. Monitor Environmental Conditions

Be mindful of the environmental conditions surrounding your commercial doors. Harsh weather, high humidity, and exposure to salt in coastal areas can accelerate rust formation. Implement additional protective measures, such as awnings or overhangs, to shield the doors from direct exposure to the elements.

In summary, to preserve the longevity and functionality of your business doors, invest in high-quality materials, frequent maintenance, and proactive rust prevention techniques. By following these tips, you can protect your investment, maintain a professional appearance, and ensure the safety and security of your business premises.


Q1. How does rust spread?

Ans. Rust, or iron oxide, spreads through a process called corrosion. Rust is the result of a chemical reaction that happens when oxygen and moisture come into contact with iron or steel. The corrosion process involves metal breakdown at the site of exposure, and if not addressed, rust can spread over the surface, compromising the material’s structural integrity.

Q2. How to remove rust from a door?

Ans. In order to remove loose rust and dirt from a door, begin by scrubbing the afflicted areas with an abrasive pad or wire brush. Apply a rust dissolver or vinegar to the remaining rust, allowing it to sit for a specified time. Afterward, scrub the surface again and rinse thoroughly. For stubborn rust, consider using a rust converter. Finish by applying a rust-inhibiting primer and a protective paint or coating to prevent future corrosion.

Q3. How to remove rust from lock and key?

Ans. A rust dissolver or white vinegar can be used to remove rust from a lock and key. Apply the solution to the afflicted regions and clean with a wire brush or toothbrush after 15-20 minutes. If required, repeat the process, then lubricate the lock with a graphite-based lubricant for smooth operation.

Q4. How to clean rusty hinges?

Ans. To clean rusty hinges, start by removing the hinge from the door. Scrub off loose rust with a wire brush, then soak the hinge in a vinegar or baking soda solution for a few hours. Scrub again, rinse thoroughly, and dry before reattaching.

Q5. How to remove rust from a metal door?

Ans. To remove rust from a metal door, first remove loose rust by cleaning the afflicted areas with a wire brush or steel wool. Apply a rust remover or a mixture of white vinegar and baking soda next. Allow it to settle for 15-20 minutes before scrubbing once more. Rinse the door well and, if necessary, lightly sand the surface. Finally, to prevent future corrosion, use a rust-inhibiting primer and a coat of rust-resistant paint.

Q6. Will a professional door repair service handle rust treatment and prevention?

Ans. Yes, a professional door repair service, such as RCI Doors™ can assist you with rust prevention and treatment, offering expertise in selecting corrosion-resistant materials, applying protective coatings, and implementing maintenance measures to ensure the longevity of your commercial doors.
