Cleaning your car wipers is a simple but crucial maintenance task that directly impacts driving safety. The best way to clean standard rubber wipers is with a 1:1 mixture of isopropyl alcohol and water, gently wiping the rubber blade with a soft cloth. This method effectively removes road grime, tree sap, and oily residues without degrading the rubber.
Dirty wipers cause streaking and reduced visibility because contaminants prevent the blade from making a clean, smooth contact with the windshield. A proper cleaning can often restore performance and extend the life of the blades, saving you money. For stubborn grime, a specialized rubber conditioner can be used sparingly, but avoid petroleum-based products as they can cause the rubber to swell and deteriorate.
Here's a quick guide to the process:
- Lift the wiper arms away from the windshield. Always secure them gently to prevent them from snapping back and cracking the glass.
- Inspect the rubber squeegee (the part that contacts the glass) for cracks, splits, or brittleness. If damaged, replacement is necessary.
- Dip a microfiber cloth in your cleaning solution. Wipe along the entire length of the rubber blade, flipping it to clean both sides. Avoid using abrasive pads or excessive force.
- Use a separate, damp cloth with plain water to rinse any residue.
- Carefully lower the wiper arms back onto the windshield.
For a deeper clean, you can also wipe the windshield with the same alcohol solution to remove any embedded wax or oil. Regular cleaning every time you wash your car is an effective preventive measure.
