How to Clean & Maintain Low-E Window Glass Without Damaging Coatings

## Caring for High-Performance Glazing Modern Low-E windows represent a significant investment in home efficiency. While microscopic metallic coatings are typically protected on the inner surfaces of double-pane units (Surface #2 or #3), improper cleaning chemicals and abrasive tools can still damage exposed coatings, scratch soft glass, and degrade rubber seals. ### The Safe Cleaning Recipe: - 1 Gallon warm distilled water - 2 Tablespoons mild liquid dish soap (e.g. Dawn) - 1 Cup white vinegar (optional, for hard water mineral removal) ### Technique: 1. **Rinse Surface Dust:** Use a spray bottle to saturate the glass and float away surface abrasive grit. 2. **Wipe with Microfiber:** Use a clean, lint-free microfiber cloth or soft sponge in overlapping circular motions. 3. **Squeegee Dry:** Pull a clean rubber squeegee blade from top to bottom, wiping the rubber blade with a dry cloth after each stroke.
