Dish soap is a cost-effective choice for outdoor window cleaning because it's gentle on glass and can effectively cut through dirt and grime. If you prefer a natural solution, use a mixture of equal parts white vinegar and water.

Combine two parts water with one part white vinegar in a spray bottle and you'll be all set with a homemade window cleaner. You can also combine warm water with a few drops of dishwashing soap if you prefer. Invest in a glass spray bottle to mix up your formula.

Smeared windows can be caused by a variety of factors, including using the wrong type of cleaning products, not cleaning your windows in the right order, improperly drying your windows, and neglecting to clean your window tracks and screens.

Try a 50/50 solution of vinegar and water for a streak-free clean. You can use a spray bottle or dip a rag in the solution, just like you would an ordinary cleaner. If you are worried about the fumes, only use vinegar for outdoor windows or mix a couple drops of essential oils to counteract the smell.
