In one sentence, describe what the following article is about:

If your windshield is clean but your wiper blades are dirty, you will still get streaks on your windshield. Gently pull your windshield wipers away from their resting position and towards the front of the car. Fill a small bucket with warm water and dish soap. Dip a clean wash cloth in the soapy water and wring it out until it’s damp. Next, use the cloth to clean the windshield wipers with smooth, gentle motions.  The windshield wipers should move from their resting position into their “cleaning” position easily. If you feel too much resistance when moving them, stop and refer to your car manual. Don’t get soapy water on your clean windshield or you may undo all of your hard work! The rubber ridge on the edge of the wipers is the most important part of the windshield wiper. If this part of the windshield wiper isn’t dry and flexible it won’t connect with the windshield properly. Using a clean microfiber cloth, gently dry the rubber ridge of the wipers with a smooth pulling motion. Next, dampen a small section of a clean microfiber cloth with rubbing alcohol. Wipe the rubbing alcohol along the rubber ridge to speed drying and condition the rubber.  Pinch the edge of the wipers with the cloth when drying them. This will help maintain the sharp edge of the rubber. Wipe in the same direction when using a cloth on windshield wipers. Start from the part closest to the car and move out towards the edge. It can be easy to forget to do this, especially if you live in a dry climate. However, even sunlight can damage the delicate rubber ridge on your windshield wiper. A damaged rubber ridge will lead to streaking and limited visibility while you drive. Besides, it’s better to be safe than sorry!  If you are handy with cars, you can replace them yourself. However, make sure you use the correct windshield wiper for your car. Most people prefer to change their windshield wipers at the end of winter just before the spring rains start.
Wash the wiper blades. Dry the edge of the wipers. Replace your windshield wipers yearly.
