Change your Wiper Blades
Wiper blades are often neglected, but one of the more important items on your car. Check and clean your wiper blades every time you stop for gas. You should change your wiper blades at least every six months.
However, you may need to change them more often during winter or in climates with harsher winters. Buy two sets of wiper blades next time and keep an extra set in your car.
Every vehicle has different sizes of blades, so before you go and purchase some for you, remove one of them and compare them at the store.
Changing them is a very simple process.
