Windshield wiper blade blades do n’t get the deference they deserve . They bump off rain , Charles Percy Snow and sometimes even ice and shite from the windscreen of your automobile and they do it quickly and smoothly , at the energy of a button . They stomach extremes of temperature , from sub - zero winter weather to scorching desert sunshine . They may have to manoeuvre for hours at a metre . And yet they ’re made out of thin , flexible India rubber – not precisely the sort of material that can take this kind of revilement indefinitely .
This makes windshield wiper blade blades one of the hardest workings – yet least perdurable – parts of your car . Over sentence , they ’ll break up , become ill-shapen or lose their flexibility .

This can really have scathe to your windscreen , as the metallic element or strong charge plate of the weapon system scrapes across the glass . You do n’t want this to go on .
Fortunately , you wo n’t necessarily have to supervene upon the entire blade assembly . Most blade implements of war will accept condom refill , giving you the option of replacing only the part that ’s damage .
