My windshield wipers have started to work less and less. It‘s only now bothering, but I‘d like to improve their function. Should I clean them or should I replace them (they are 2 and a half years old).Thank you!
The time to replace them is when they leave a streak. The rubber has become unpliable and they do not make a good contact with the glass. If it is slow, the reason is something else. Replacing them with a new one does not make them run faster. The reason for low speed - it is of wrong size for your car. Wrong size (usually large size) puts additional load on the wiper motor and you could burn the motor to replace them sooner than needed.
Standard estimate with normal usage is that you should change them every six months. At 2 1/2 years, I would say it's time to change them. Make sure you consult your owner's manual or go to an auto parts store and ask to make sure you get the correct size for both wipers.
Replace them before they damage your windshield, windshield wipers should be replaced as needed.
