The discussion focuses on finding the ideal ratio of Simple Green and glass cleaner for effective windshield cleaning without streaks. Participants highlight the unpredictability of mixing different cleaning formulations and recommend consulting a cleaning-products formulation chemist for precise ratios. A user mentions using "Rain X," a water-repellent product that enhances cleaning efficiency by preventing the need for windshield wipers at high speeds. Caution is advised against using cleaners with dissolved salts, silicates, or phosphates in automotive window cleaning systems.
PREREQUISITESAutomotive enthusiasts, cleaning product formulators, and anyone seeking effective methods for maintaining streak-free windshields will benefit from this discussion.
Not good generally to mix different cleaning formulations. Consult your local cleaning-products formulation chemist. My best guess is use some formulation which has no dissolved salts, such as, do not include any silicates, nor phosphates in the cleaner. There are window/glass cleaners specifically intended form the cars' automatic window cleaning system. Glass and window cleaners will usually have some combination of solvents and might or might not include ammonia. The solvents are usually some combination of water, ethanol, isopropanol, butyl cellosolve or some other such glycol-ether, and maybe a small amount (very small) of a detergent. I do not specifically know the typical formulation of the stuff that is meant for the cars' window cleaning system - check the label.David K said:We are wondering if there is an ideal ratio of simple green + glass cleaner to get the bugs off & keep it streak-free. Thought there might be a chemist with the ideal ratio. We will experiment and let you know what happens.
