How to remove rust from bike?

If you own a bike, then you would be aware of the importance of its proper cleaning and maintenance. Lack of cleaning and bike tune-up will cause inefficiency during your ride and will lead to rust and grime build-up.

Bike rust can be an annoying and problematic if left unchecked. With rust on the bike frame, components and parts can become corroded or fused together, making it harder to use or difficult to repair if left undone for a long period of time. 

Rust is also capable of weakening certain parts of your bike, which could put you at risk in a crash, making proper rust removal essential for safe cycling. 

To remove rust from bike parts like chains or frames, you can use multiple methods and with the use of some household items and tools. 

Simply, you can use a brush with baking soda or vinegar to scrub away the rust and then use steel wool to buff it off.

Here in this post, I will discuss four methods to remove rust form your bike:

1-Using Vinegar
2-Using Baking Soda Paste
3-Using WD-40
4-Using Chemical Rust Remover

Now let’s discuss the step-by-step process of these four different methods answering the question; How to remove rust from bike?

Methods to remove rust from bike

1- Using vinegar


The first and most basic method to clean bike rust is using cleaning vinegar. Vinegar is a commonly used item in almost every home. You can find it easily in every kitchen. It is an invaluable resource when it comes to cleaning, as it does not leave stains and has a good amount of acetic acid to combat tough dirt and grime. 

Follow below simple steps to remove rust:

1-Take a spray bottle and fill it with vinegar.

2-Add half a teaspoon of salt to strengthen the mixture and to increase its effectiveness.

3-Sake the spray bottle well.

4-Now apply the vinegar to the rusted area.

5-Let it sit for 15 mins, then spray again and leave for another 15 mins and repeat 3 times.

6-After that, rinse the area with water and clean the area properly.

7-Once cleaned, dry the bike parts with a piece of cloth where you applied the spray.


  • After cleaning the bike area, ensure to dry it properly. Vinegar itself can cause corrosion if not rinsed off and dried properly.
  • If the removable parts of the bike are affected by rust, you can soak them in a vinegar mixture in a large plastic container for 45 mins.
  • If rust remains are still visible, you can repeat the above process for a couple of days.

2- Using Baking Soda Paste

The second best method for removing rust is baking soda and water mixture with some drops of lemon juice.

This method is also very easy to try and is highly effective in removing rust. Simply follow the below steps, and you will be amazed by the results:

1- Take a container and add half a liter of water to it. After adding water add 250 grams of baking soda in it.

2- Mix with a stirrer or any wooden piece. 

3- Add 4-5 teaspoons of lemon juice to the mixture.

4- Now apply the baking soda mixture to rusty areas of the bike.

5- Leave the mixture to sit for 20 mins.

6- After that, use a brush to scrub the mixture and rinse with warm water.

7- Dry the bike parts after cleaning.


  • This method is effective for small rusty areas.
  • If you don’t get the desired results on the first go, then repeat the process.
  • You can also use steel wool to scrub the rust away.

3- Using WD-40

Wd-40 is very useful in removing rust from various household items. You can also use it on your bike parts. The process is relatively simple; just simply the WD-40 on your bike’s rusty parts and let it sit for 15 mins so it can penetrate deep inside and dissolve rust. After that, use a brush to scrub the rust away.

However, be careful while using WD-40 on your bike chain. You can use it to remove rust from the chain but don’t consider it as bike lube. Just apply it on the bike chain, let it rest for 15 mins, scrub it off and clean your bike chain and apply proper chain lube.

4- Using Chemical Rust Remover

If no other method is working for you; it’s better to try chemical rust remover. You can easily find these in any hardware store near your area. 

1- Apply the chemical on your bike’s rusty area using a brush.

2- Rub the area with a brush and continue rubbing until the rust starts to get off.

3- It will take some time, depending on how many parts of your bike are affected by rust.

4- You may need to apply some extra force and pressure while scrubbing the rusty parts with a brush.

5- If the brush gets too dirty due to rust, it’s better to clean it with water and reuse it until all rust is removed.  


  • Be careful when using any chemical rust remover as they are highly reactive and can damage your skin.
  • Use protective glasses and gloves when using chemical rust removers.

How Does Acid Rust Removal Work?

Rust removal acids are either water-based solutions, weak acids, strong acids, or alkalis that react with rust and dissolve it. Rust removal acids act as a base on the rust, causing an oxidation reaction that breaks down the structure of the rust and releases it from its bond with the metal. 

Oxidizing agents such as hydrogen peroxide or ammonium phosphate also work well to remove surface rust quickly. The advantages of using these solutions include easy application and quick results. Additionally, they are not overly corrosive and are relatively cost-effective. 

Water-based methods are also effective in removing rust but take a bit more time, usually involving soaking the parts in a water-based solution for several hours before cleaning off any residue. 

Should I Clean My Rusty Bike Chain Or Replace It?

This will depend on the current situation of your bike chain. If there are only little spots of rust, you can use any of the above methods to clean it. However, if the chain is too corroded, further efforts may prove futile. In that case, better to replace it altogether and save yourself the frustration. 

Fortunately, replacing a bike chain isn’t difficult nor overly expensive – you can replace the chain yourself, or you can take it to your local bike shop for some help on getting a new drivetrain that’s perfect for your style of riding.
