6 Methods to Remove Rust from Wrought Iron

Especially in the monsoon and damp winter season when you leave your furniture outdoors. It gets into contact with the air, water, and oxygen. And bam! Your iron furniture mixes up with rust. 

This rust not just weakens your furniture,  but eventually disintegrates it. And that’s how you lose your memorable piece of furniture forever.

But, removing rust is not as hard as people think. Let’s get the methods.

Before You Start: Clean 

Before starting the rust removing method, the first step is to remove loose rust. That is, if there’s any. 

Scrub it through a dry wire brush. Furthermore, to remove tiny rust flakes or dirt you can use a dry paintbrush. And to remove deeper rust you can use coarse sandpaper. 

Furthermore, the following methods are also helpful in removing other stains. Like dispelling rust from steel sinks.

Method 1: Use White Vinegar to Clean the Rust 

Vinegar is the most effective rust remover because of its acidic and antimicrobial properties. Furthermore, with a pinch of salt its acidic intensity increases. 

Thinking about which brand of vinegar would be best? Now, you don’t have to rake your brain over it. I have recommended the best-selling vinegar in the market:

Product 2

The mentioned vinegar can be used for different types of cleaning. 

Now, put some vinegar on the rusted area and leave it for 10 minutes. After that scrub the area with aluminum foil or rag. Rubbing with aluminum foil helps loosen the rust residue. 

Remember, it will require some. So, be patient. Furthermore, this method can also be used on metal tools along with furniture. 

You can also clean wrinkled clothes with vinegar as well.

Method 2: Baking Soda

Baking soda is a popular item found easily in every household. It is known to be a common home remedy for cleaning. 

Mix some baking soda with water. You can also sprinkle the vinegar directly on the rusted area before spraying water on it. 

Basically, you need to create a thin layer of baking soda and water mixture on it. 

Make sure to coat the rusted surface evenly. After creating the thin layer, let it rest for an hour or two. Then gently scrub it with a cleaning cloth or paintbrush. You may need to repeat the process multiple times. 

And if it’s heavy rust, mix hydrogen peroxide instead of water. 

Method 3: Salt and Lime for Rust Removal 

Lime juice with salt crystals will make the rust soft and easy to remove. Salt while acting as an abrasive reacts with citric acid in lime. This makes a perfect solution for removing stubborn rust.  

Simply put some mixture of lime juice and salt in a bowl. Apply this mixture and let it leave for two to three hours. 

Lime and salt can be used separately as well. You just have to sprinkle some salt first and then lime. Once again, you need to form a thick layer and leave it for a while.

And lastly, just wipe the surface. 

Method 4: Potato to Clean the Rust

Potatoes? Sounds strange, right? 

Well, it actually works!

Potatoes have oxalic acids to act against rust. It is very helpful in removing brownish stains from metal. 

Just cut a potato and add some salt or rub dish soap all over it. Now use this half piece of potato as a scrubber. Rub it over the rusted area. If there are rusted corners, pouring a potato and dish soap mixture on it may help.   

When the rust is weakened by the solution, clean it off with a cleaning cloth. 

Method 5: Oxalic Acid For Rust Removal

Oxalic acid removes rust stains and is a fast product for rust removal. However, it’s a little risky to use. Take the following precautions.

  • Wear rubber gloves on your hands.
  • Goggles for eyes.
  • To avoid inhaling use a nose clip. 

After taking the necessary precaution, pour oxalic acid and water mixture on the rusted surface. Try to pour it in small amounts. Use a dry wire brush or steel wool to scrub. 

But remember, oxalic acid is not recommended as a first method to remove the rust. Because it is possible that you damage your furniture beyond repair. 

Method 6: Remove the Rust with Coca-Cola

Beside being our favorite cold drink, this carbonated solution is perfect for dissolving metal oxide. 

This is the best DIY solution for cleaning stubborn rust stains from metal surfaces. Simply pour enough of it on the rusted area. Rub it with a sponge or clean cloth. Apply the process multiple times for the rust to remove it completely. And that’s it.

A warning for you, don’t try cola for cleaning foggy windows. It can sometimes damage glass particles.
