You can’t see with dirty eyeglasses

Or with windshield wipers in poor condition. That’s why the DGT (Spanish Traffic Agency) recommends “changing them every year, even every six months, because heat and dirt deteriorate the rubber”.

Wipers allow good visibility in the rain or on tracks with a lot of dust. For them to work correctly, check the water tank: better completely full than half full. We recommend mixing products that improve cleaning and, when cold, add antifreeze.

There are also liquids that make drops slip and prevent mosquitoes from sticking to the glass.
