Why Rust Occurs on Bikes?


If you’re familiar with rust, you’d know that rust is caused by a chemical reaction known as oxidation.

But why does this chemical reaction happens on your steel bike frame?

There are a couple of answers. However, the most common reason why rust occurs on bikes is because of the exposure to road salt or mud.

If you’re riding a road bike – it’s most likely that you’ve come across road salt. But if you’ve been enjoying the trails and getting your mountain bike dirty – this is most likely the cause.

However, whatever the cause is – it doesn’t take long for rust to permanently damage a part of your precious bike.

How to Remove Rust on Steel Bike Frame

If you don’t spot rust on time or if you don’t do anything about it – rust will permanently start ruining your bike frame, piece by piece.

That’s why it’s important to take action and remove rust from your bike frame as soon as you notice it. Even after you remove the rust, it’s important to take steps in order to protect your frame from rust in the future.

You won’t even have to visit the shop and here’s a list of the items you will need:

  • Bowl
  • Brush
  • Scrub pad
  • Baking soda or vinegar
  • Dry rag

Creating a Mixture


The first step is going to make you feel like you’re a chemist as you will have to mix the baking soda and water in a bowl in a 1 to 1 ratio. Mix it until it turns into a thick paste, and somewhere mid-mixture, you can squeeze a couple of drops of lemon to enhance the properties in the mix.

Taking the Action

With a brush (or a sponge), apply the paste evenly on the bike frame, from the spot where you see the rust, to the length of the bike frame this spot is located at.

For example, if you’ve found rust at the bottom of your bike frame, you should apply the paste evenly at the bottom, across the length of the frame.

You should evenly apply the paste, even at the spot where the most rust is. After that, let it sit about 15 minutes so it can break down the rust.

The Hard Part


The task is simple but it’s a task not many people, so I like to call it the hard part.

Can you guess what it is?

After the 15 minutes of leaving the paste on your bike frame, it’s time to scrub the rust which has hopefully broken down by now.

Use a scrub pad to scrub the paste off the bike frame. At this point, you’ll notice the rust coming off as well (which is good). Flaking of your steel frame is also something you might notice, so don’t let this worry you.

This is a step you can repeat a couple of times if you notice that there’s still some rust left remaining.

The last time you repeat the process, leave the paste on for 10 minutes, and instead of scrubbing it off, wipe it off with a dry rag.

You want the frame to be dry and that there are no stains left at the frame.

How to Keep Your Steel Bike Frame Protected From Rust


Rust doesn’t ask any questions and it will attack any bike – however, there are a couple of things you can do to prevent rust from occupying your bike.

Ideally, you should store your bike in a dry and cool place. If you are riding in a lot of rain, installing fenders is a smart option to keep the bottom of your frame at least somewhat clean and dry.

Washing your bike often (especially after muddy or rainy rides) is something you should always do.

There are even anti-rust sprays suitable for bikes, so if you aren’t on a tight budget – investing in any of these types of sprays is a great idea.


Mountain bikes can last for years if they’re kept free of rust. The same goes for road bikes.

It’s important that you inspect your bike for rust at least once a month. The sooner you spot rust, the easier you will remove it.

However, the longer time passes by, the harder time you will be having with eliminating the rust as a whole.

And we all know what happens if the rust on steel bike frame isn’t removed as a whole. It spread and sooner than you know it, your bike structure might not be as stable and strong as it is now.
