Overview
- Recent Argentine coverage published on Sunday and Monday reports that cleaning often fixes noisy, jumping or streaking wipers without immediate replacement.
- Experts say the problem is dirt buildup—dust, grease, insect remains and tree resin—that breaks the rubber’s smooth contact with the glass and produces chirps and marks.
- The agreed step-by-step method is to lift the wiper arms, wipe the rubber in one direction with a soft, low-lint cloth moistened with water and mild soap or isopropyl alcohol, rinse and dry before lowering the arms.
- Recommended materials are simple: about a litre of water, a few drops of neutral soap or isopropyl alcohol, and a lint-free cloth or kitchen paper; drivers should avoid harsh solvents such as gasoline, kerosene or acetone.
- If noise, bouncing or streaking continue after cleaning the rubber or if the rubber shows visible cracks or loss of shape, experts advise replacing the blades to restore visibility and safety.
