A Guide To Rust Protection For Bikes

We all long for (and love!) a bike trail that’s wet, muddy, and full of dirt, but we’re not sure our bicycle can say the same. Did you know that if your bike is exposed to water, it can leave it vulnerable to rusting? Although it may only be a small amount at first, the unwanted rust can spread quickly and eat away at your bike’s metal, which ultimately affects performance. If you let the rust go beyond repair, permanently damaging the metal parts of your bicycle, you are left with no other option but to invest in a brand-new one. Not ideal. So, how do you save yourself some pennies by rust-proofing your bike?

The best way to prevent rusting is to store your bike safely away when it isn’t being used and apply a rust-proofing lubricant to protect it when you are riding it – enjoying those wet and wild rides guilt-free! WD-40® Smart Straw Multi-Use is great for safeguarding metal bicycle parts from natural elements. The easy-to-use product quickly penetrates under oil and debris to provide a protective coating on the metal surface to prevent corrosion and rust. What’s more, thanks to the clever Spray2Ways technology, you can ensure that you only apply the formula to the rust-prone bicycle parts and avoid the tyres and braking surfaces. The 360° valve also allows for upright or upside-down application allowing you to spray at any angle.
