Wipers are an integral part of any vehicle. Their utility of keeping the windscreen clean during extreme driving conditions ensures safety of occupants at all times. From an Indian point of view, majority of us as end users do not pay heed to the need of taking care of this particular component. This is evident from the fact that the older your car gets, this component tends to degrade with time causing major concerns for the person behind the wheel who could face a problem citing vehicles coming from the opposite direction resulting in an accident or for that matter damage to the exteriors and under body parts of his or her machine.

There is really no rocket science attached to it, it is fairly simple. One just needs to walk up to the windscreen lift up the wiper and check the state of the rubber underneath which remains in contact with the glass. First signs of degradation can be seen in the form of cracks that tend to appear on the rubber. Another indication of worn out wiper is inflexibility of rubber. In both these scenarios in order to avoid damage to the windscreen and also maintain clear visibility the best step is to replace both pairs. Ideally even if there are no signs of degradation, we would recommend that in every six months one should re-examine their condition to keep a close check.
