We're going to talk about windshield wiper blades. Now that may seem like a pretty mundane topic, but think about how important your vision is: We protect our eyes. If we need contacts or glasses, we taken care of them too. And, well, wiper blades are critical to our vision when we drive.

We really ought to think about wipers as part of an important safety system. We should think about maintaining safety – not just responding when our wiper blades fail: how many times have you been caught off-guard by the first storm of the season with a streaky windshield you can barely see out of.

Wiper blades live outside the vehicle, exposed to heat and sun in the summer and cold and ice in the winter. It's no wonder that they get dry, brittle and torn.

We recommend changing wiper blades twice a year – before they're so damaged that they don't work. If you replace them in one of your spring and fall oil changes, you should always have wiper blades that can get the job done.

Some of us live in areas with more extreme weather and temperature conditions. You might just live somewhere where it rains more or has more ice so your blades wear out faster.

When it comes to wiper blades, it's important to think of it as maintaining this safety component by replacing your blades before they fail. That'll keep you seeing clearly in all conditions.
