28. Kill Weeds
If you are an experienced gardener, you probably have your own way to get rid of weeds in your garden. You can use good old manual labor or vinegar. But WD-40 is also a great way to get rid of weeds like, thistles.
Just spray some WD-40, leave it be, and pull it out (with root and all) once it withered. The best part? WD-40 is a safe and effective alternative for weed control, especially for isolated areas and stubborn intruders like thistles.
