Usually, the wiper blades should be replaced approximately once a year. If the car is driven a lot, a reasonable interval for replacing the wiper blades may be six months. It is recommended to replace the wiper blades whenever you notice that the wiping performance has deteriorated. Poorly maintained wiper blades may scratch the surface of the windshield. Even newer wiper blades may be damaged in freezing temperatures if the wiper blades are pulled off from a frozen windshield too hard, for example. After that, the wiper blade will no longer work well.

Methanol is more toxic than ethanol. In addition, methanol is produced from fossil fuels, unlike ethanol, which is renewable.

Water is better than no washer fluid at all, of course, but it does not clean the windshied very effectively. The A-Katsastus’ screenwash fluid for summer is specially designed to remove insects from the windscreen. The ready-to-use screenwash solution should also be used to wipe down the wiper blades from time to time. This way, the wiper blades stay clean and in good condition for longer.
