Opening Rusty Locks
If you do not keep intruders out of your house, make sure to get good locks. However, there are times when a lock gets so rusty that you can’t open it even with the right key! It is no match for WD-40.
Removing Stickers
We love stickers as a way to show off the advocacies and beliefs we have. At some point, you will want to take them off for some reason. When you plan to resell your car, use WD-40 to remove the stickers.
