Comprehensive Guide to Cleaning Your Mountain Bike Chain

Keeping your bike in top shape starts with a good post-ride cleaning. First, hose off loose dirt, grime, and mud to avoid scratching the paint later. Then, fill a bucket with warm water and gentle dish soap like dawn for a cleaning solution.

While the soapy water tackles the rest of the bike, focus on your drivetrain. Use a chain cleaning tool or brush to remove caked-on grime depending on your lube. Dry lube washes off easily but may require scrubbing, while wet lube offers long-lasting protection but attracts dirt and might need a degreaser. Below is our guide on how to clean your Mountain Bike Chain.

Regular Cleaning After Trail Riding

Materials Needed:

• Clean rag or cloth
• Chain lubricant
• Soft brush (optional)
• Chain cleaning tool (optional)

Steps for Regular Cleaning After Trail Riding:

Inspect the Chain:

• Lift the rear wheel off the ground and slowly rotate the pedals.
• Check for dirt buildup, rust, or tight links (links that do not bend easily).

Initial Wipe Down:

• Use a clean rag to wipe off any surface dirt from the chain. Wrap the rag around the chain and backpedal to remove loose debris.

Lubricate the Chain:

• Apply a drop of chain lubricant to each roller (link) while backpedaling slowly.
• Allow the lube to sit for a few minutes to penetrate the links and rollers.

Final Wipe Down:

• Use the rag to wipe off excess lubricant. Hold the rag around the chain and backpedal to ensure an even application and removal of any extra lube.
• You can use a hair blower if available to dry off the moisture in the chain.

Bonus Tip:

• Using WD-40: WD-40 is not a lubricant but can be used as a cleaner. Spray it onto the chain, let it sit for a few minutes, and then wipe it off with a clean rag. Follow up with a proper chain lubricant.

Thorough Cleaning (Once every 3 months or so)

Materials Needed:

• Chain degreaser
• Two brushes (old toothbrushes work well)
• Clean rags
• Water
• Soap (dawn)
• Chain lubricant
• Optional: Chain cleaning tool, chain splitter

Warning:

• Avoid soaking the chain in a degreaser. Extended soaking can reduce the lifespan of the chain by removing lubrication from the rollers and causing premature wear.

Steps for Thorough Cleaning:

Preliminary Wash:

• Rinse your bike with a hose to remove loose dirt, grime, and mud.
• Mix a teaspoon of dish soap (like Dawn) in a bucket of water and wash the bike, focusing on removing surface dirt. Note that the drivetrain may still be greasy.

Remove the Chain

Apply Degreaser:

Scrub the Chain:.

• Use a brush (old toothbrushes work well) to scrub the chain thoroughly. Scrub each link and roller to remove dirt and grime.
• Ensure you scrub from multiple angles to reach all the nooks and crannies.

Rinse the Chain:

• Rinse the chain thoroughly with water to remove all traces of the degreaser.
• Ensure the degreaser is completely washed off, as any residue can prevent proper lubrication.

Dry the Chain:

• Pat the chain dry with a clean rag to remove excess water.
• Allow the chain to air dry completely to ensure no moisture is left, which could cause rust. You can use a hair dryer if available.

Clean the Drivetrain Components:

• While the chain is off, clean the chainrings, cassette, and derailleur with a brush and degreaser.
• Rinse and dry these components as well to ensure they are free of dirt and degreaser.

Reinstall the Chain:

• Reattach the chain to the bike using the master link or by reconnecting with a chain splitter.

Lubricate the Chain:

• Apply a drop of chain lubricant to each roller while backpedaling slowly. Ensure the lubricant penetrates the links.
• Focus on applying lubricant to the inside of the chain where it contacts the chainrings and cassette.

Final Wipe Down:

• Wipe off any excess lubricant with a clean rag to prevent dirt attraction.

Bonus Tips:

• Using Chain Wax: Chain wax can provide a more durable and dirt-resistant coating than regular lubricants. After cleaning and drying the chain, apply the wax according to the manufacturer’s instructions, which usually involves melting the wax and submerging the chain or using a wax-based lube. See out guide to chain waxing.
• Environment-Specific Lubricants: Use dry lubricants in dusty conditions and wet lubricants in muddy or rainy conditions to match the riding environment.

Lube Types Explained

Dry Lube:

Wet Lube:

Choosing the Right Lube:

Consider your riding conditions most of the time. If you face frequent rain or muddy trails, a wet lube is ideal. For dry and dusty environments, a dry lube is your friend.

Here are some additional factors to consider:

• Riding Frequency: Frequent riders may benefit from a wet lube’s durability, while occasional riders might prefer the ease of cleaning with dry lube.
• Personal Preference: Some riders prefer the drier feel of a dry lube, while others prioritize the heavy-duty protection of a wet lube.

Additional Tips in Cleaning Your Mountain Bike Chain:

Clean the Chain Regularly

• Make chain cleaning a part of your regular bike maintenance routine to prevent excessive buildup of dirt and grime, which can lead to premature wear​.

Use Proper Cleaning Tools:

• Invest in a good chain cleaning tool to make the process more efficient. These tools are designed to clean the chain from multiple angles and can save time​.

Avoid Power Washers:

• High-pressure water can strip grease from bearings and other components. Use a gentle stream of water to rinse off dirt instead​.

Use Bike-Specific Cleaning Products:

• Avoid using household cleaners that can damage the chain and other bike components. Stick to bike-specific degreasers and lubricants​.

Inspect the Chain:

• Regularly check for signs of wear, such as elongation, stiff links, or rust. Replace the chain if it shows significant wear to prevent damage to the drivetrain​.

Apply Lubricant Properly:

• After cleaning, apply lubricant sparingly and precisely to each roller of the chain. Over-lubrication can attract more dirt and grime​.

Let Lubricant Settle:

• Allow the lubricant to penetrate and set into the chain for several hours or overnight before riding. This ensures better protection and performance​.

Clean Other Drivetrain Components:

• Don’t neglect the chainrings, cassette, and derailleur. Clean these parts regularly to ensure the entire drivetrain runs smoothly​.

Dry the Chain Thoroughly:

• After cleaning, make sure the chain is completely dry before applying lubricant to prevent rust formation​. Use a hair dryer if you must.

Consider the Riding Environment:

• Use dry lube in dusty conditions and wet lube in muddy or wet conditions to match the riding environment and optimize performance​​.
