How to Make Your Own Glass Cleaner
If you want to avoid harsh chemicals and save some money, make your own glass cleaner. Mix 1 cup of vinegar and ½ teaspoon dish soap with 1 gallon of warm water. Pour your mixture into a spray bottle and use it like you would any commercial glass cleaner. Another way to make glass cleaner is to soak citrus peels in vinegar for a few weeks. Then, strain the citrus mixture and pour it into a bottle. Mix in 1 cup of water and use it to clean your glass products. You can also try pouring club soda into a spray bottle and using it as a glass cleaner.
