Why do locksmiths hate WD-40?

Using WD-40 on locks is risky and tricky, but it’s a common DIY fix for stuck or squeaky locks. Many homeowners do it because they are unaware of the issues with WD-40 in lock maintenance. The benefits are immediate: the noise goes away, and the lock glides smoothly. WD-40 is the go-to for those who don’t want to hire a professional because it’s easy to use and can be found at hardware stores and even supermarkets.

Its popularity is further boosted by its ease of use. Using WD-40 may seem more convenient than searching for and purchasing lock-safe lubricants that can’t usually be found in regular stores. However, there’s a price for that convenience.

While WD-40 vs lock-safe lubricants may seem like a small difference, the long-term effects on lock mechanisms can be big. The most concerning issue here is that your initial WD-40 fix masks the damage being done. The moment you see that something is wrong with your lock, you likely won’t realize it’s related to your previous use of the spray. You may then need to have it repaired by a professional or replace the lock (which is often necessary after regular use of the spray). When, after some time, your lock starts to show the first signs of damage or malfunction, you will use WD-40 again, closing this vicious circle unknowingly.

The dangers of using WD-40 on locks go beyond temporary problems and can be serious. Internal component corrosion is one type of damage that can cause lock malfunction or total failure. Often this means a whole lock replacement which is an expensive outcome that could have been avoided. Homeowners can choose the best lock care for their locks by knowing these WD-40 issues in lock maintenance.

You need to use the right methods on locks to make them last and perform optimally. Locksmiths recommend using specialty lubricants made for locks, like silicone-based sprays or dry graphite powder, instead of WD-40. These lubricants work and don’t attract dirt or leave behind any harmful residues.

Use a soft brush or compressed air to remove any debris from the keyway. Don’t over-apply the lock-specific lubricant by using only a small amount. Your locks will last longer if you give them regular maintenance with the right supplies and that also means dependable performance.

Avoiding WD-40 in lock repairs is 50% of success. The rest involves following expert methods regularly.
