Opening Rusty Locks
If you want to keep your things from criminals and intruders, you might as well invest in a great lock. However, it would be of no use if you yourself can’t open it. Rusty locks may do that, so make sure to bring some WD-40 – aside from the key, of course – whenever you need to open old locks.

Removing Stickers
Stickers are definitely cool. You may even have some on your bumper. “Green Peace?” Sports stickers? There can be many kinds of stickers that you may find necessary to stick to your car. But if you need to remove them, just make sure that you have some WD-40 in hand to make the process easier.
