Working with ladders is dangerous so maybe you can get your window cleaner on the job !
While you can use straight vinegar and water to clean windows, adding a few simple ingredients to your homemade window cleaner will make it even more effective.
This means to avoid using window cleaner or other products with ammonia.
If you are in a pinch and don't have soda or peroxide around your house, you can squirt some window cleaner onto the fabric.
Mix one part window cleaner or liquid dishwashing soap to four parts water.
