Best Windshield Cleaner Mixture
A mixture of four parts alcohol, one part household liquid detergent and five parts water is the best solution for
cleaning bug residue, road oils and other materials deposited on vehicle windshields - at least - that is what we like
to use. Paper towels are by far the best implement to use with this mixture.
The organic residue found on windshields consists of insect skeletons and fluids, grease, oil, rubber and asphalt,
along with minerals such as quartz, mica, clay feldspar, kaolinite and calcite.
