What is the composition of automotive windshield washer fluid formula?
1 Answers
Automotive windshield washer fluid formula: By mass, 60% water, 39% ethanol, 0.3% AEO, 0.2% LAS, and 0.5% other additives, mixed to produce automotive windshield cleaner, which appears as a blue transparent liquid with non-irritating ethanol odor and a nearly neutral pH value. The main components of dirt adhering to automotive glass are mud, dust, tree sap, insect resin, oil stains from gasoline/diesel combustion, residual polishing wax, insect remains, etc. Mud and dust can be washed away by water, so the main solvent in automotive windshield cleaner should be water. However, oil stains and animal/plant gums are difficult to remove with water alone, so organic solvents must be added to the cleaner to enhance its solubility for these contaminants.
