If you're windshield wipers aren't doing a very good job, you are one frustrated person. As drivers, we tend to forget about wipers until we need them - in the rain - but there is nothing worse than turning on your wipers, only for them to make it even harder to see. This can be a serious bummer, but also a serious safety concern!
If your wipers are old, they need to be replaced. However, if you have recently replaced them and they are still not working properly, here are some potential causes;
When wipers are run-down, there's not much that will bring them back. Dry, brittle, or damaged wiper blades need to be replaced.
If your windshield is always dirty, your wipers suffer slight damage every time you turn them on. Sometimes it's hard to keep things clean, but using those windshield cleaning area at gas stations will help your wipers from time to time.
Believe it or not, you need to clean your wipers too. Wipe them down from time to time. This will make them much more efficient, and you'll be able to use them for longer before needing a replacement!
Any time your wipers slide across a dry windshield, there is damage. Water acts a lubricant to make the wipers squeegee properly and easily clean the surface of the glass. Even almost-dry wiping (clearing mist or dew) from your windshield can be damaging. Before you turn on your wipers, it is a good idea to use your windshield washer fluid to pre-wet the glass and loosen up anything that you don't want your wipers to drag around.
During the winter months, snow and ice can build up in the corners and crevices of your wipers. When scraping you windshield, gently rub your hand along the surface of the blade to remove any frozen bits! Also be sure to check the are above the blade that gives the wipers that springy, form-fitting-to-the-windshield action. Ice loves to form there and can cause a huge dead spot in your wiping area.
