Replacement car wiper blade rubber from the company Guard, compatible with vehicles that have a driver-side wiper blade size of 530mm. Replacing a worn-out rubber is an economical and easy solution, as you do not need to change the entire wiper blade with its attachments. Some of the signs that warn the driver for immediate replacement are the noise they make during use, as well as the water streaks that appear on the windshield from incomplete sweeping.
