Should you use wd40 on a bike chain?
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.
