To create a streak-free outdoor window washing solution, cleaners only need vinegar, dish detergent and water. All of these ingredients get mixed together in a spray bottle before application.
To make the cleaner and ensure a streak-free appearance on dirty windows:
- Mix the ingredients in a spray bottle and stir
- Dry with a microfiber cloth
- Rinse again with just water and vinegar
Combine 1/4 cup white vinegar, 3/4 cup warm water and 1/2 teaspoon of dish detergent in the spray bottle, gently stirring to mix it.
After spraying the mixture on the window, use a microfiber cloth to buff it dry.
If there are any remaining streaks or if there is any residue left, rinse again with just water and vinegar.
