If you did not take care of your bike for a while or if it was sitting out in a wet climate, there is a chance that it will get exposed to rust. This is an occurrence that can cause a series of problems, so today, we are going to talk about how to fix a rusty bike chain and list some useful methods to do so.
If you encounter this situation, it is essential to resolve it as soon as possible, as rust can create extra friction, and the chain can become more susceptible to breakage. Luckily, cleaning a rusty chain is not a difficult task if you know what to do. If the rust has set in and you cannot remove it, you can replace the chain altogether. There is a lot to cover regarding this subject, so let us begin.
Check if the Chain Can Be Cleaned or if You Need a Replacement
The first step you should take is to see if the rust situation is fixable with cleaning or if the chain is beyond repair and requires a replacement. It is something that entirely depends on how much rust has set in. Are there just a couple of rusty stains, or is the chain completely covered in it?
If the latter is the case with you, it means that it is time to replace your chain, and luckily, buying a new one is a relatively inexpensive investment, while there are various stores you can get it from. Also, if you are not confident in replacing it by yourself, you can take it to the local bike store and let the professional do all the work.
On the other hand, if there are just a couple of rust spots on the chain, you can clean it and fix the problem in no time. You will need the proper cleaning products and some effective methods to apply them, which we will list in the sections below.
Methods for Cleaning a Rusty Bike Chain
If you have established that your bike chain does not require a replacement, it is time to figure out how to clean the existing rust stains. We did a bit of research and found some effective ways you can resolve this problem, and you will find them down below.
The first thing you should try is to use the least invasive method and clean the chain in a normal way. If the level of rust on it is minimal level, you can try using a degreaser as it can be highly effective in removing the rust stains, and it is a method that does not require much effort.
If there is not too much rust, you can just apply a degreaser and leave it on for a while, but if the chain requires more work, you should remove it from the bike and let it soak in the degreaser. Taking it off is not a difficult task, but if you do not feel confident in doing it, it would be wise to take several pictures of the whole mechanism before taking the chain off so that you can figure out how to get it back after the cleaning is done.
Again, this should be done only if there is too much rust. If you decide to do the cleaning with the chain on, place a degreaser on a wet cloth and use it for wiping the rust down. You can also spray it directly on the chain and leave it on for a bit. After you give it some time to be applied completely, wipe it off.
If you opt to remove the chain, leave it soaking in a degreaser for at least 20 minutes. Afterward, just rinse it thoroughly in warm water, let it dry, and you are ready to set it up again.
2. Steel Wool and Lime Juice
If you still have rust on the chain after you attempted the first method we have listed, it is time to look for some alternatives. Lime juice is very effective in eating away rust as it is rich in citric acid, which does an incredible job of doing this.
Simply apply some lime juice on a steel wool pad and scrub the rust stains until they start to dissolve. This is a method that is known to provide good results, but if it does not do the trick for you, we have more solutions in store.
3. Baking Soda
Using baking soda to remove rust is an effective, simple, and accessible method to opt for. Pretty much everyone has it in their kitchens, and it can work for both minor and severe rust stains. Simply add baking soda to water and stir until it becomes a thick paste. Make sure to add water and baking soda in equal amounts to get this effect.
If the rust on the chain is severe, you should add a bit more baking soda than water. It is also important to point out that the amount of paste you will apply entirely depends on the rust level – the more rust there is, the more paste you will need.
After you make the paste, apply it on the chain by using the spatula-like tool, as it will make spreading it a lot easier. Once the paste is applied, leave it on for at least 15 minutes, and scrub it off with pads or a sponge afterward.
Using a WD-40 spray can be highly effective in rust removal, as it is a multi-purpose chemical widely used for various household purposes. It is a type of chemical that clean the rust without doing any type of physical damage to the chain or body of the bike.
It is essential to know that WD-40 is not a lubricant but cleaner, so you will be required to apply some lubrication solution to the bike chain afterward. Simply apply the spray to remove the surface rust from the metal parts, and just lubricate it after you are done with the whole process.
The final recommendation for cleaning rust from your bike chain is the solution we all have within households – vinegar. This is a highly effective method, as vinegar is rich in potent acetic properties, which makes it great for removing rust. If you do not have vinegar at hand, you can also use Coca-Cola.
One of the more effective ways to apply vinegar to the chain of your bike is by using a spray bottle. Simply pour the vinegar into a bottle and spray it on the chain, and then use a small brush with tinfoil to scrub off the rust. Make sure to scrub hard, and you will start noticing pieces of it falling off.
You can also try adding some baking soda to vinegar to make this cleaning solution more effective. After you apply this solution, leave it on for about 10 minutes so that it does not corrode metal.
How to Prevent Rust on Your Bike?
Now that we have listed some of the most effective methods for rust removal, it is time to explain how to prevent it from forming in the first place. It is essential to take care of your bike properly and to do it on a regular basis. In the section below, we have listed some of the most important ways to prevent rust from forming on your bike.
1. Keep the Chain Oiled
If you drive your bike frequently, it is important to have a toolbox at hand and to keep bike chain lube set in it. Your chain and other parts of the bike that move constantly are often exposed to various elements, so it is essential to keep them lubricated and lube them after every ride. This is highly important as this type of maintenance can prevent iron oxide.
2. Ensure That Your Bike Is Stored Indoors
One of the most effective ways to protect your bike chain and other metal parts of it is to keep the bike stored indoors whenever you are done riding it. Ensuring that the bike is stored inside will keep it safe from various elements and harsh weather that are the most common cause of rust formation.
The place where you want to store the bike should be clean and dry, which is another essential way to prevent rust from forming in the first place.
3. Wipe Your Bike Down After It Was Exposed to Rain
Rain and other elements can be some of the main causes of rust formation, which is why it is essential to wipe your bike thoroughly after it gets exposed to such conditions. You can use a rag to wipe your bike down and make sure to pay special attention to parts like chain and brake components.
4. Clean the Bike Thoroughly After Riding It on Rough Terrain
When you drive your bike on rough terrain that is packed with a lot of gravel, salt, and grime, it is critical to clean your bike after you are done riding it. This will prevent corrosive elements from sticking to your bike components and keep the rust at bay long-term.
5. Be Warry of Sweat
It is completely normal and natural to sweat while riding a bike, especially during intense cycling sessions. However, sweat can also be a cause of rust on your bike, especially around the places where the sweat from your face drips.
In order to get in the way of this, make sure to bring along the towel and place it in the stem area, which will stop the sweat from dripping on the important parts of your bike.
