Wiper blades are made of rubber (a material resistant to abrasion) and the windshield is made of glass, which is a smooth and non-abrasive surface. This tells us that wear of the blade should not be much of a concern unless the blade is cracked, torn or dried up by the sun.
Cleaning the windshield with wiper blades involves getting rid of dirt or small particles like sand, dust, road film, and let us not forget the bugs! These small particles embed themselves in the pores of the blade, resulting in streaks and smudges on the windshield. Occasionally cleaning the blade with a small brush and a good soap cleansing is beneficial. However, on a day-to-day basis, adding pressure on the blade with the Sure Wipe spring will make the blade flip-flop more energetically at the end of its stroke to get rid of this dirt.
The Sure Wipe spring will also keep your blade snug against the windshield to get a thorough cleaning.
