- First thing, remove everything on window surface and window sill. Apply Seventh Generation Glass Cleaner to window. Use a microfiber cloth or a 100 percent cotton shirt or special glass microfiber, clean from left to right, top to bottom.
- The reason you need 100 percent cotton or glass microfiber is because other cloths leave dust behind that make the glass dirty.
- Newspapers and magazines sometime will leave marks on glass or a toxic residue in your house.
- Never leave windows wet.
- Vinegar (3:1) can be used if you don't have glass cleaner.
