Rusty bike lock – four weeks of annoyance followed by a five-minute fix

Rain, snow and wind have made my bike lock rusty. I put up with the consequences for way too long and bought WD-40 much too late. Silly, really. After all, I’m fully aware that the penetrating oil will get almost anything moving again.

My bike lock’s giving me a really hard time. At times, I’m hunched over my bike for up to five minutes in an attempt to open or close it. I’ve got so close to pushing it over, hoping it will bring down all the other parked bikes with it. Or simply abandoning it, praying somebody will steal it.

Why?

After weeks of cursing, of risk-taking – I had to leave my bike parked, unlocked, in the middle of Zurich one time to catch my bus – and lethargy, I pull the emergency brake and buy WD-40.

Gaffa holds the world together, WD-40 makes it move

The penetrant in the blue bottle fixes anything that should move but doesn’t. For the reverse problem, I recommend Gaffa tape. Join the forces of these two and you can solve any problem.

Penetrating oil has a low surface tension. This means it gets into even the smallest crevices where it tackles oil, grease, soot and rust, among other things. Perfect for my small, rusty lock cylinder. The wee spray straw that comes with a can of WD40 makes things even easier.

I give it three to four sprays, let the liquid sit for a few seconds, and go in with the key to spread everything around even more. The lock already pops on the second turn. To make sure this wasn’t a one-off, I lock and unlock the bike dozens of times. It works every time.

The fix took a whole five minutes. This makes me feel frustrated. Not with the fix but with myself. I constantly put off simple things like that. If only WD40 would put my backside in gear.
