All About Wipers

[sparc179]

Pls correct me if I am wrong, basically, it cleans the wiper blade lang? So if I clean the wiper blade by using alcohol only, using this gadget is better?

I think it shaves the frayed edges off so you get a more even wiper blade, less streaking if any. It doesn't really clean the surface.

alcohol? on rubber? wont this affect the shape and make the edge flacid? lol

I always thought rubbing alcohol will make rubber dry and brittle, I only use joy dish-washing liquid mixed with water.


Next question: Does the shape of the wiper blade frame make any difference? Specifically those Banana-Type wipers which supposedly push down on the wiper blade during high speeds making them more effective. Or is it just aesthetics?
