Most of the drivers will only be concerned with the normal operations of their windscreen wiper blades at the front of the car, very few actually actually take notice of the rear windshield wiper blades. In fact, not many people actually use their these wiper blade at the back of the car until they need to.
The rearscreen wiper blade is actually as important to the driver as those in front. Though drivers are more concerned with their visibility in front, it is also important to know that a clear view of the back of the car is needed while driving.
Due to the obscure nature of the rear window wiper, many car owners tend to neglect it and not take care of it. They usually fail to notice that it is time to replace the best wiper blade until its too late. To know when to replace the rear wiper blade is simple, you just have to note if the swiping is clean. If the blade is leaving streaks of water after swiping, then the rubber has probably worn out and needs replacement.
Rear windshield wiper blade is usually much shorter compared to those in front. Front wiper blades are typically 16 inches and above in length, those at the back are only 11 to 14 inches. They are also cheaper than their longer counterparts. You can get one for less than $10 easily.
Check the condition of your rear wiper blades today and replace it if necessary. Do not wait until you are driving in thunderstorm to know that you need a clear view of the back of the car. Blind spots are dangerous, so try to reduce it when driving. It is all in the name of safety.
Recommended Windshield Wiper Blades For Winter
Driving during winter has always presented a different set of difficulties for drivers compared to summer or spring time. This problem is mainly due to the sub-zero temperature that the car is exposed to during the whole season. Besides having to change to tires for more surface grip, drivers also have to remember to switch your wiper blades to one that is more for winter use. It is all in the name of safety because wiper blades not made for winter will malfunction when you need it and this will affect your visibility when driving.
Reasons To Swap Wiper Blades
Most of the wiper blades used by cars are actually made of rubber, these will function normally during spring and summer. However, once we enter winter, the performance of rubber deteriorates rapidly because this is not a material that withstands cold as well as silicone. The rubber wiper blades will become stiff when exposed to freezing temperatures. The stiff blades can do more harm then good, not only will it not able to clear away the snow and particles on your windscreen, in worst cases, it might even scratch your windshield.
What To Look For In Winter Wiper Blades
With so many problems associated with using with using rubber wiper blades, what should you be looking for when considering a winter wiper blade? First of all, the wiper blade has to be made of materials that can withstand the harsh temperatures in winter. This is to prevent it from hardening. A common material used for winter purpose is Teflon-like. This will not freeze and still be able to flex to swipe the windshield clean of snow and particles. Moreover, such blades have a protective coating on the its frame that prevent snow and ice from forming on it.
It is recommended to change wiper blades every 6 to 9 months, so your normal wiper blades should last you through the year before changing to the safer winter purpose ones. If the old ones are still in good condition, you can keep it and switch back again after the winter season.
How To Keep Your Wiper Blades In Good Condition To Last Longer
Most wiper blades have a lifespan of 6 to 9 months before you will see the need to replace it. Silicone blades usually last longer than rubber wiper blades. However, the lifespan is largely dependent on how you use the wiper blades and maintain it so you could get your money’s worth.
Please Do Not Do These
Most drivers will find it a convenience to use the wiper blades and swipe off any residues they see on their windshield. However, swiping on a dry surface has detrimental effects on the wiper blades. Dry surface will produce more friction when swiping wiper blades and this causes more wear and tear to the blades. This problem is exacerbated during a hot weather. The UV rays is already damaging enough to the blades. The additional heat will damage the wiper blades faster.
You also should not use the wiper to remove dirt and grime accumulated as these grainy materials can wear off the blade edges faster. It is also not advised to swipe ice or snow on the windscreen as these will cause deformity to the blades. Snow is also heavy and causes much stress to the whole blade system.
Solution To Maintaining Wipers
Most of the damage done to the wiper blades are due to it operating in dry and hot conditions. All it needs is windshield washer fluid to make swiping smoother for the blades. You can easily purchase one bottle of washer fluid from gas stations. Mix it into the storage tank located under the bonnet of the car.
Though wiper blades are cheap accessory, it plays an important part in driving safety. Do not wait until its worn out before you realize the need to change. The best way is to use it appropriately to prolong its usefulness. Not only is it cost efficient, it also gives the driver a peace of mind.
Why You Should Buy Silicone Wiper Blades And Not Rubber Blades
It is often a split decision drivers have to make a choice between buying silicone or rubber wiper blades to replace their worn out ones. A key consideration will be the price difference between these two materials. Silicone made blades are usually more expensive, by about 20%, compared to rubber made blades. However, we would think that there is more to price to think about when choosing a replacement wiper blade.
Wiper blades may be a small accessory to the car but its reliability and performance will have significant repercussions to the driving experience. Imagine you are caught in a thunderstorm or a snowstorm, your wipers are unable to clear the windshield properly, leaving you to drive under bad visibility. Bad wiper blades can endanger your life.
Analysis of the materials
Rubber is mostly made up of a compound of natural and synthetic rubber mixed with other chemicals. It is a common and low cost material used throughout the world.
Silicone is an inert material, meaning it is stable and durable. It is typically used in high stress equipments such as sealant and cookware.
A key property of Silicone which makes it useful for wiper blades is its stability under extreme temperature change. This makes it useful for all seasons in a year. It is also resistant to UV rays. For cars in the tropics, your wiper blades will often be worn down by the sun and has to be replaced often. With silicone wiper blades, you can be sure of a longer lasting performance.
Rubber wiper blades are noisier and produces a screeching sound when they slide on the windscreen. On the other hand, silicone wipers has natural lubricant ability that helps a smoother slide.
If you can afford that extra buck, go for silicone made wiper blades since it provides so many benefits not available by rubber based ones.
How Wiper Blades Affect Aerodynamics Of Your Car
Though you may not realize it but the windshield wiper blades you use can affect the aerodynamics of your vehicle when it is in motion. Wiper blades that are not streamlined or well in contact with the surface of the windscreen will cause more drag while moving and decrease the overall efficiency of the vehicle. The implications of this includes more fuel consumption and a reduced driving experience.
WindLift – The Cause Of Drag
The increased drag caused by wiper blades can be attributed to the Windlift phenomenon. This is due to the moving air getting under between the wiper blades and the windscreen surface. It provides an upward force on the wiper blades, thus pushing it away from the surface. By having the wiper blades jutting outwards will affect the overall aerodynamics of the vehicle. It causes a distortion to the flow of air and add to the resistance of the car moving forward.
Causes Of Windlift
Windlift is just the reason that caused the drag of the car but what are the factors that cause windlift? There can be a few but we will highlight the more prominent ones. Firstly, this could be due to design of the windscreen of newer cars. As more manufacturers design windscreens that are more curved to improve the aerodynamics, the downside is that conventional wiper blades will not be able to have a full surface contact. Just imagine placing a straight pole against a curved surface, there is definitely space allowance on either end. So ironically, this new windscreen design will cause more air to deflect off it and push the wiper blades outwards. This has in fact reduced the efficiency rather than improve it.
Secondly, the problem could also lie with the design of the wiper blades. Older framed wiper blades are very rigid and stiff. The latest wiper blades in the market are designed aerodynamically that will mold itself to the windshield.
The spring tension at the arms of the wiper blades will also affect the amount of contact with the windshield surface. If there is not spring tension, it may not hold the blades in place and consequentially, loosen the contact with the glass surface.
Choosing the right wiper blades to fit your car is a small but important task, If possible, spend that premium to get better designed wiper blades that will resist windlift and give good wiping performance. Safety is paramount compared to aerodynamics.
