When to (really) replace and how to keep toothbrushes working properly.

1) Typical interval (but with common sense)

Portuguese sources on automotive maintenance indicate that, as a rule, wiper blades can last around 1–2 years , varying with use and climate.

2) Signs that never fail

  • stretch marks and areas that need cleaning

  • noise and vibration

  • Rigid/dried rubber (sun and UV accelerate wear)

3) Simple cleaning that prolongs life

Controlauto recommends cleaning the wiper blades with a cloth and windshield washer fluid (or warm soapy water), and emphasizes that using wiper blades on dry glass or thick ice can damage and scratch them.

Monthly routine (5 minutes)

  • Wipe the eraser with a damp cloth (from end to end).

  • Clean the glass inside and out.

  • Check the washer tank level.
