Buying Guide: Window Washing Fluids — Key Considerations
- Check whether the formula is safe for tinted windows, LOW-E glass, or windshields. Ammonia-free options are generally gentler on sensitive surfaces.
- Concentrates like the Unger options save money per gallon but require accurate dilution. Ready-to-use fluids save time but may have higher per-use costs.
- For indoor windows and mirrors, look for streak-free results. For outdoor windows, hoses or outdoor-targeted formulas can simplify cleanup.
- If you’re sensitive to fumes or have pets, ammonia-free or methanol-free formulas can be preferable.
- Some cleaners are multi-surface (windows, glass doors, car windshields, mirrors). Decide if you need one solution or specialized products.
