surprising uses for WD-40 you never thought about

Opening Locks

We’re not suggesting you use this next trick to open anybody else’s house, but we all had at least one time where you get back home after a long day at work, and your key won’t open the door. The lock is too damn rusty! What do you do…? Don’t worry, you’re not gonna have to sleep in the street, as long as you remember to take your loyal friend WD-40 with you. Just spray some WD-40 on your rusty door lock, wait for five minutes and then try your key again. And you’re in!

Time to take a shower and wind down, all thanks to WD-40.
