In this guide, we discussed the steps to create a homemade window cleaner that is safe, non-toxic, and environmentally friendly without using alcohol or ammonia. The ingredients needed for this solution are white vinegar, distilled water, lemon juice, liquid soap (preferably natural and biodegradable), and a spray bottle. To make the solution, mix 1 cup of distilled water, 1/4 cup of white vinegar, 1 tablespoon of lemon juice, and 1/2 teaspoon of liquid soap in a spray bottle. Shake the bottle well to ensure that all the ingredients are mixed thoroughly. Test the solution on a small area first before using it on all your windows. Apply the solution onto the window surface and wipe it off with a clean, lint-free cloth or paper towel. Use a circular motion to avoid leaving streaks. Dry the windows completely with a dry cloth or paper towel. Some tips to keep in mind while using this solution are to use a microfiber cloth for best results, avoid cleaning windows in direct sunlight, use a soft-bristled brush for stubborn stains, and store the solution in a cool, dark place to prolong its shelf life. By following these simple steps, you can enjoy clean and streak-free windows while also being environmentally conscious.
