Windex Crystal Rain is an ammonia-free version of the well-known glass cleaner, utilizing an Isopropanolamine base. The 23 fl oz bottle features an upgraded "Leak-Shield" chassis, with reinforced threading and improved piston-seal tolerances. This engineering update is designed to prevent "weeping" at the gasket when the bottle is tilted, adding a layer of reliability for storage and heavy use.
The formulation is designed to be safe for surfaces where ammonia might cause degradation, such as tinted window films, chrome, and stainless steel. The "Crystal Rain" scent offers a synthetic fragrance profile intended to mask the solvent base. Key usage points include:
- Custom-notched neck to ensure the trigger assembly stays aligned and tight during use.
- Ammonia-free chemistry suitable for electronic screen bezels and tinted automotive glass.
- High-leverage trigger designed to reduce hand fatigue during large-scale glazing projects.
Tests show that ammonia-free variants can dry slightly slower than traditional versions, which may require a few extra passes with a dry cloth to ensure a perfect finish. While it handles everyday dust and fingerprints well, it may require more effort on heavy protein-based soilage compared to the original ammonia formula.
If you require a specialized formula with rose vinegar for descaling light water spots, the Pink Stuff Miracle Glass Cleaner is a unique hybrid option.
