Consider going with the change of seasons, replacing the blades with at the beginning of winter and again for summer-two seasons that prove particularly challenging for wipers. Therefore, our experience suggests that beyond a quick monthly inspection, it would be wise to plan for wiper replacement twice a year.
HOW TO INSTALL MICHELIN GUARDIAN HYBRID WIPER BLADES DRIVERS
When the project started, about half those cars had wipers that needed replacing, showing that drivers often don't notice the slow degradation and leave wipers on longer than they should. When we last tested wipers, we conducted an exhaustive assessment of more than a dozen windshield wiper models on 185 staff members' cars.
Because we found that a wiper blades will typically provide very good or better performance when new, with performance dropping off quickly, most blades should provide adequate performance after about six months when they should be replaced. Depending on the model, deterioration showed up on the windshield as streaking (leaving lines of water behind), smearing of the water (instead of clearing it), or missed areas of wiping. When new, we saw that all of the tested windshield wipers provided very good or excellent performance initially, but most quickly degraded after a few months of regular use. Lesson here: Don't equate a high price with high quality. In our testing, we have found that some of the best blades are among the least expensive. (You might need a small screwdriver or hammer to tap the old blade off.) Our research shows that most car owners replace the assembly, rather than just the blade.Īll wiper blades are marketed with great promise, and it can be difficult to sort through the claims and hyperbole. It's often more convenient to replace the whole blade assembly-just pull the old wiper off the metal arm and push the new one on until it's tight. Experience shows that replacing an insert can be a frustrating task whose grief simply isn't worth the money savings. It's becoming harder to find replacement inserts where only the rubber is replaced into the existing frame and while inserts can save money, installing them requires deft use of needle-nose pliers. For a smaller wiper blade, you can pay as little as under $10 and for a large blade of 24 or 26 inches, you can pay $25 or more. Prices vary greatly depending on the brand, type, and size. Major brands that you are likely to see include Anco, ACDelco, Bosch, Goodyear, Michelin, PIAA, Rain-X, and Trico. Look in your car's owner's manual, measure the blade, or ask at an auto-parts store for the proper fit. Windshield wiper blades come in many sizes, even on the same car. Even though it may not get as much use as the front wipers, it is exposed to the elements and can fail over time. If one is worn out, its mate can't be far behind.ĭon't forget to check the rear wiper, if your vehicle has one.
When the time comes for new blades, remember to replace them in pairs. Further, be sure to clear snow and ice from the windshield in the winter before dragging the wipers across the uneven surface. You might be rewarded with a couple more months of a clear windshield without spending money on replacements. Simply put windshield washer fluid or glass cleaner on a damp sponge or rag and wipe debris off the rubber and the windshield where the wiper rests. If the wipers are in decent physical condition but not clearing the windshield effectively, clean them. If the rubber is rigid or chipped, or produces nonstop streaking, you need new wipers. Lift each wiper arm off the glass and run your finger along its rubber edge. To get the most from your existing wipers, inspect them periodically. The good news is that, based on our testing, you don't have to spend a lot of money to get good performing windshield wipers, but you might need to replace them every six months or so.
