There are a few simple reasons to follow the specialists’ advice and actually replace your windshield wipers two times a year. The hot summer sun can be a real challenge for rubber. It will dry it, but also make it very rigid. Obviously, cleaning the windshield becomes a challenge, while the creaking noises will kill you. On the other hand, defrosting substances and low temperatures have similar effects, so wipers must be replaced after the wintertime too. Opt for quality when investing in a new pair.
