Should I Replace Just the Wiper Blade or the Entire Wiper?

For wipers, you only need to replace the rubber blade. The original wiper frame is quite sturdy, so you can just replace the blade without changing the entire set. In most cases, the wiper rubber should be replaced every six months to a year, but this depends on the actual usage of the wipers. If the wiper blade is not replaced for a long time, the aging blade can slightly affect the wiper frame, causing it to age as well. To minimize the impact on the wiper frame, it is essential to replace the blade promptly when needed. Wiper maintenance tips: When using the wiper to remove dust from the windshield on sunny days, always spray windshield washer fluid—never operate the wiper dry. For stubborn or hard dirt on the glass, clean it manually. These substances can easily damage the wiper blade, leading to poor cleaning performance or even affecting the wiper motor in severe cases. When lifting the wiper blade for car washing or routine cleaning, hold the "back" of the blade and gently return it to its position—avoid snapping it back. In winter, use an ice scraper to clear ice chunks from the windshield before using the wiper to reduce the burden on the wiper. Wipers can generally be divided into two types: traditional intermittent wipers and rain-sensing wipers. Rain-sensing wipers are mostly used in mid-to-high-end models. A good wiper should be heat-resistant, cold-resistant, acid- and alkali-resistant, corrosion-resistant, fit the windshield well, reduce motor load, operate quietly, have strong water repellency, and be soft enough not to scratch the windshield—all to ensure clear visibility. How to replace a wiper blade: First, lift the wiper, then detach it from the metal arm. Use a small metal hook to grip the original blade for stability. Pry up the metal hook and pull out the old wiper blade. Remove the plastic cap on one side of the wiper, insert the new blade, reattach the plastic cap, and clamp the metal hook to secure the new blade in place.
Having driven for over a decade, I find wiper replacement to be a common issue. Generally speaking, whether to replace just the rubber blade or the entire assembly depends on your vehicle. Older cars with traditional wiper blades make it easy to replace just the rubber insert—costing around 10 yuan to purchase and install—as long as the metal frame isn’t rusted or damaged, saving money and being eco-friendly. However, many modern cars come with beam-style (frameless) wipers where the rubber is embedded, making disassembly tricky and prone to improper installation; replacing the whole blade is often more affordable and hassle-free, costing around 30–50 yuan. Personally, I first inspect the wiper’s condition: if the rubber is cracked or frayed but the frame is intact, I replace just the rubber; if the frame is bent or loose, I swap the entire unit for safety. Don’t forget to check them regularly before rainy seasons—clear visibility is crucial, so don’t prioritize savings over safety. Wipers typically last about a year, but choosing higher-quality products can extend their lifespan.
