Chain cleaning

In my opinion, it is imperative to know the exact procedure of applying WD-40 on your beloved bike. Look at the below steps –

  1. Clean the chain: Hold it! Before applying the WD-40, clean the bike chain completely. You can take the help of a dedicated chain cleaning tool to remove any kind of dirt, old lubricant, and grime from the chain.
  2. Apply WD40: After cleaning and drying the chain, apply it all over the bike chain. For an even spray and better result, hold the can around 7-8 inches away.
  3. Wipe off excess amount: Let the WD-40 do its magic by allowing it to penetrate for a few minutes. Afterward, get a clean cloth and wipe off the excess amount of it. This will eventually remove any kind of debris that the spray may have loosened.
  4. If required (re-apply): If you feel that the chain is still rusty or dry, try re-applying it. However, it is not the ideal long-term option for chain lubrication.

Moreover, it can evaporate in a flash, resulting in an inappropriate lubrication.
Easily available – Due to its easy availability and being affordable in pricing terms, it is a convenient option for cyclists.Not specifically for bike chains – Even though WD-40 helps clean bike chains and remove rust, it is not the ideal lubricant for cleaning bike-chains.
Water displacement – It can displace water from the chain, which reduces the risk of rust formation.

It is a quick fix for a dirty or squeaky chain. Even though it is more of a cleaner than a lubricant, the WD-40 can be used on bike chains and overall on bikes too. The only issue that I came across is that it comes off rapidly during wet conditions, and that has been reported by many cyclists.

To make things very clear, it won’t harm your bike chain in any way. There have been tons of bikers who have been using this cleaner on their bikes, and there haven’t been any issues.

I would say a “NO” for wet conditions, but in dry conditions, it can be a top-tier lubricant than others. The simple reason for this statement from my side is because it is less oily.

WD-40 alternatives

There are several alternatives to WD-40 for lubricating your bike chain. Have a look at them –

1. Chain-specific lubricants

These lubes are intended to adhere to the surface of the chain and offer lasting lubrication in different conditions. Additionally, they are of different types with varied weather options.

Final thoughts

As fancy as it sounds, WD-40 is a versatile water-displacing spray that is popular for its penetrating and lubricating properties. If I had to talk about using it on bike chains, it impresses me even after being known as a short-term solution as a lubricant.

However, I need to clarify something about this water displacement spray. I would suggest not using it on disc brakes, as there have been many instances where riders afterward were unable to use their brakes properly. Moreover, it isn’t suitable for wet conditions as it comes off quickly.
