Why Rust Is Bad for Your Bike Chain

Rust is one of the biggest enemies of a bike chain. When metal is exposed to moisture and oxygen, it can start to corrode and rust.

A rusted bike chain can cause several problems for both the rider and the bike itself. Here are some reasons why rust is bad for your bike chain:

1. Causes Friction

When a bike chain is rusted, it creates friction between the links, making it more difficult to pedal.

This can make your ride less efficient and more difficult, especially if you’re biking uphill or over rough terrain.

The increased friction also causes more wear and tear on the chain, which can lead to more rusting and damage.

2. Damages Your Gears

When a rusted bike chain is used with other components, such as the gears, it can hurt those components as well.

The rust particles from the chain can get stuck in the gears, causing them to wear out faster and even break. This can be a costly repair and can leave you stranded without transportation.

3. Shortens the Life of Your Chain

A rusted chain won’t last as long as a well-maintained one. Over time, the rust will eat away at the metal, causing the chain to weaken and eventually break.

This issue can be dangerous if it happens while you’re riding, and it can also be expensive to replace the chain.

4. Can Be Difficult to Clean

Rust can be difficult to remove from a bike chain, especially if it has been there for a while. It’ll require special tools and chemicals to remove it.

And if you don’t do it correctly, it can cause even more damage to the chain.

Now that we’ve covered the answer to why rust could be bad for your bike chain, let’s get to the guide on how to clean your bike chain without removing it.

Tools and Materials You’ll Need

First off, here’s the list of items you’ll need to take care of your bike’s rust:

1. Chain Lubricant

Using a chain lubricant will help loosen any rust particles stuck to your chain. Use a degreaser or a specialized chain lubricant for this.

2. A Brush

A brush is necessary to scrub the rust particles from your chain. You can use a stiff-bristled brush like a toothbrush or a chain cleaning brush.

3. A Rag or Cloth

You’ll need either of them to wipe away any excess lubricant or rust particles that come off your chain during the process.

4. Cleaning Solution

You can use a mild dish soap or a specialized bike cleaning solution to clean your chain. Remember to dilute the cleaning solution with water before using it.

5. Gloves

Wearing gloves is crucial to protect your hands from any chemicals or lubricants you may come into contact with during the cleaning process.

Work Stand or Bike Rack

Using the stand or the rack to hold your bike steady while you clean the chain is highly recommended. This will make it easier to clean the chain thoroughly and evenly.

This is the bike rack I recommend (check it out on Amazon).

Step-by-Step Guide

Here’s a step-by-step guide to remove rust from a bike chain without removing the chain:

1. Clean the Chain

The first step is to clean the bike chain rigorously. This will help remove any dirt or debris that could make the rust worse.

Wipe away any loose dirt or debris with a clean, dry rag to clean the chain.

Scrub the chain with a brush or a toothbrush, making sure to get into all the crevices. In this step, you’ll use the degreaser or a mild detergent to help loosen any stubborn grime.

After cleaning the chain, rinse it with clean water and pat it dry with a clean rag.

2. Apply a Rust Remover

Once the chain is clean and completely dry, apply a rust remover. The market has a lot of options, but you can also make yours using household items.

One effective homemade rust remover is a mixture of baking soda and water.

To have this mixture, mix the baking soda and water to form a paste, then apply the paste to the rusted areas of the chain.

Let the paste sit on the chain for 10-15 minutes, then use the brush to scrub away the lifted rust. Rinse with clean water and dry it again with a dry rag.

3. Apply Lubricant

After removing the rust from the chain, it’s crucial to use lubrication to help prevent future rusting and keep the chain running smoothly.

Use a high-quality lubricant designed for bike chains only and apply it to the chain, ensuring it gets into all areas.

Then, wipe away the excess lubricant.

Tips for Maintaining a Rust-Free Bike Chain

If you ride in wet conditions, dry the chain as soon as possible to prevent further rust formation.

Don’t forget to lubricate the chain regularly. How often you do it will depend on how often you ride your bike and the conditions you ride in.

As a rule of thumb, apply lubricant every 100-200 miles or every 2-4 weeks.

Lastly, check your bike chain for signs of wear and tear. If you notice any damage or excessive wear, replace the chain right away.

Common Mistakes to Avoid When Removing Rust from a Bike Chain

Removing rust from a bike chain can be a delicate process that requires patience and care.

Here are some common mistakes to avoid when removing rust from a bike chain:

1. Using Harsh Chemicals

One of the most common mistakes people make when removing rust from their bike chain is using harsh chemicals.

While these chemicals may remove the rust, they can also damage the metal of your bike, leading to further problems down the line.

2. Over Scrubbing

While it’s important to scrub the rust off your bike chain, scrubbing as well can cause damage to the metal. If you scrub too hard, you risk removing the protective layer on the chain, which can make it more susceptible to rust.

3. Neglecting to Lubricate the Chain

Not lubricating the chain leads to further rusting. Make sure to apply a generous amount of chain lubricant after cleaning it.

4. Not Protecting Other Components

It’s important to protect other components such as the derailleur and brakes. Harsh cleaning solutions and lubricants can cause damage to these components.

Cover the derailleur and other sensitive parts with a plastic bag before starting the cleaning process.

5. Not Wearing Gloves

Always wear gloves when handling these cleaning solutions to avoid skin irritation or chemical burns.


Taking care of your bike shouldn’t be a hassle. As you can tell, the guide included only 3 steps of cleaning. By having everything prepared beforehand, you’ll completely expunge rust from the bike chain without removing it.

If you took your cleaning game seriously and cleaned your bike every time you took it out for a walk, we can guarantee you that you won’t spend hours cleaning it.

Keep in mind that maintaining your bike in tip-top form can prevent any accidents and hardships along the way. Happy riding everyone!
