- Lubricant
Step 1: Remove the bike chain
When you’re ready to remove the bike chain, follow these steps. If your chain has a master link, locate it and use pliers or a chain tool to detach the link, separating the chain into two halves. If there is no master link, use a chain breaker tool to push out a pin and carefully remove the chain from the bike, noting its routing through the front and rear derailleurs.
Different bike chains may have slight variations in their disassembly methods, depending on the chain type (single-speed, 5/6/7/8-speed, 9-speed, 10-speed, etc.), so refer to your bike’s user manual or consult a bike mechanic for the appropriate disassembly method.
Step 2: Clean the bike chain
Gather all the necessary materials, including a degreaser, a cleaning brush, a small container, and a towel or cloth. Now dilute the degreaser according to the manufacturer’s instructions, and then remove any loose dirt or debris from the chain by wiping it down with a rag or old newspaper.
Next, submerge the bike chain in the prepared degreaser solution, allowing it to soak for a few minutes to loosen the built-up grime and old lubricant.
After soaking, take the chain out of the solution and use a stiff-bristled cleaning brush to scrub it thoroughly. Pay special attention to the areas with rust spots, making sure to clean all sides of the chain, including the rollers and pins.
Rinse the chain under clean water to remove any remaining degreaser and loosened rust particles. Depending on the severity of the rust and the cleanliness of the chain, you may need to repeat the soaking and scrubbing process. Stubborn rust spots might require multiple rounds of cleaning to ensure complete removal.
By thoroughly cleaning the bike chain with a degreaser solution and a cleaning brush, you’ll eliminate dirt, grime, and some rust. However, to address the remaining rust spots more effectively, it’s essential to employ various rust removal techniques, which will be explained in the following points (3 and 4).
Once you’ve completed the cleaning process and addressed the rust, proceed to rinse and dry the chain carefully before applying the appropriate lubricant. This will ensure that your bike chain operates smoothly and efficiently, extending its lifespan and improving your overall cycling experience.

Step 3: Rinse and Dry
After completing the rust removal process and thoroughly cleaning the bike chain, rinse and dry the chain properly. Rinsing will ensure that any residual cleaning solutions or rust particles are removed from the chain and all you have to do is clean it under running water. Also, make sure to use your hands to agitate it and dislodge any remaining debris.
Once the chain is rinsed, it’s time to dry it completely. For this use a clean towel or cloth to wipe down the chain and remove excess water. Alternatively, you can hang the chain up to air-dry for a few hours, ensuring that no moisture remains trapped between the links. Proper drying is essential to prevent any new rust from forming on the chain during storage or subsequent rides.
Step 4: Lubrication
After the bike chain is clean and dry, the next step is to apply the appropriate lubricant as lubricants reduce friction between the chain’s moving parts, ensuring smooth operation and protecting against future rust formation. Choose a high-quality bike chain lubricant that matches the weather conditions and riding environment.
To lubricate the chain, apply a small amount of lubricant to each individual chain link while turning the pedals backward. This allows the lubricant to penetrate the chain’s rollers and pins and after applying the lubricant, wipe off any excess with a clean cloth. Over-lubricating the chain can attract more dirt and debris, leading to a less efficient and messier cycling experience.
Step 5: Re-install the chain
With the chain now clean, dry, and properly lubricated, you can now reinstall it on your bike. Carefully route the chain through the front and rear derailleurs, ensuring it is properly seated on the chainrings and cassette cogs and if your chain has a master link, connect the two ends by inserting the pins back into place or locking the master link securely.
Ensure that the chain has the proper tension and is aligned correctly on the chainrings and cassette. Incorrect chain tension or misalignment can cause poor shifting performance and chain noise while riding. If you’re uncertain about reinstalling the chain properly, it’s always a good idea to consult your bike’s user manual or seek assistance from a professional bike mechanic.
Best Rust Remover Techniques for Bikes
When cleaning the bike chain, you may still encounter some persistent rust spots that require specific techniques for effective removal. You can use different cleaning agents for cleaning the chain even if you don’t have the WD40.
These cleaning agents will not only help in removing the rust from your bike chain but will also eliminate rust from your bike gears.
Here are some common rust removal methods:
Using White Vinegar for Rust Dissolution
White vinegar is a natural acid that can effectively dissolve rust and to use this method, soak the rusted parts of the chain in a small container filled with white vinegar.
