You’re in the garage preparing to clean off your bike and want to make sure your chain is nice and lubricated for the next ride. You’re looking around for the right product to use on your bike chain and see a can of WD-40. If you’re like me you wondered…
Can I use WD-40 on my bike chain? Yes, WD-40 can be used and will not damage your bike chain. It is primarily a cleaner, but also a light lubricant that will last best in dry conditions. It’s not the best lubricant for riding in wet conditions, because it will come off quickly.
What is WD-40?
WD-40 was created in 1953 by a small company called Rocket Chemical Comapny. They were trying to create solvents and degreasers that would prevent rust. It took them 40 times to figure out the formula that is now known as WD-40. The name stands for “water displacement” with the 40 referencing the number of attempts it took to create.
Sometimes you’ll hear that WD-40 is only for removing water and keeping things rust-free. I have heard and read from other cyclists claiming that WD-40 isn’t a lubricant. This is not true. According to the WD-40 website, “it is a unique, special blend of lubricants.“
When to Use WD-40 on Your Bicycle Chain
WD-40 is primarily a cleaner, but also a lubricant. While there are reputable organizations and bike repairmen who say otherwise it is actually fine to use WD-40 on your bike chain and bike. The main issue with WD-40 is that it is a LIGHT lubricant and so it will come off quickly if you’re riding in wet situations.
To be very clear – WD-40 will not ruin your bike chain. It’s a great product not only for cleaning your bike chain, but also as your main lubricant. There are many cyclists who primarily use WD-40 and have had no issues. In dry conditions it can arguably keep your chain cleaner longer than regular bike lubricants, because is less oily.
WD-40 is best for cleaning off gunk, grime, and dirt from your bike chain and derailleur. Spray it onto your chain as a degreaser, and it’ll help knock off the grime. Once you’ve degreased the chain you’ll want to use soap and water to get it sparkling clean. After the chain has been degreased, cleaned with soap and water, and dried you’ll need to apply a lubricant.
You could also use it as the only lubricant on your chain, and it will last for 8 to 12 hours of riding in dry conditions.
