In the event that you take a gander at these elastic edges, you have to concentrate on the lower edge of the sharpened steel part particularly. This is 99% where your wiper cutting edges either function admirably or let you down.
Firstly, replacement windscreen wipers are produced using an elastic or silicon compound all together that they don’t scratch your windshield amid utilization. So they shouldn’t scratch, squeak, shiver or streak. The long base edge of the elastic sharpened steel itself is made with a square cut under 1mm wide, with clean square “sharp” corners. They effectively rub away the messy downpour, mud, coarseness and other street trash that always places your windshield consistently, paying little mind to the climate.
