Formulation Notes
Fast-evaporating, ammonia-containing glass cleaner for windshields and interior glass.
Method: Mix water, IPA, and EGBE. Add ammonium hydroxide slowly with cooling. Add surfactant and colorant. Properties: pH 10.0–11.0, clear blue liquid, viscosity water-thin. Isopropanol at 5% provides rapid evaporation (boiling point 82 °C) that prevents water spotting, while the low level of ammonium hydroxide (0.8%) breaks down oily films from outgassing vinyl dashboards and smoker residue without producing the harsh fumes of household ammonia cleaners . Note: The ammonia content is intentionally kept below 1% to avoid damage to tinted window films or anti-glare coatings. For an ammonia-free variant, replace ammonium hydroxide with 2.0% monoethanolamine; adjust pH to 9.5–10.5.
