Lemons, grapefruit and oranges all have natural cleaning properties. While the juice is known to cut through grease and grime, the rind also contains strong cleaning agents.
method 1 -Squeeze the juice of one lemon and add it to a spray bottle. Fill the bottle with water, then add two drops of natural liquid dish soap or 1/2 teaspoon of baking soda. The soap or the baking soda both act as a water softener to make the solution gentle on the glass. Shake the bottle very well after adding all the ingredients.
Method 2-Adding 2 teaspoons of fresh-squeezed grapefruit or orange juice to a spray bottle filled with water also works as a glass cleaner. Make sure to add 2 drops of natural liquid dish soap or baking soda to soften the water.
Method 3- another way of using citrus in a natural cleaning recipe is to add the rind of one lemon, grapefruit or orange to a bottle of water. Cap the bottle and let it sit for a few days. The rind will start to break down, releasing its cleaning properties into the water. When the water seems to have a nice amount of the citrus essence infused in it, simply strain 1/2 cup of it into a spray bottle and fill the rest with water. Adding dish soap or baking soda may not be necessary.
Vinegar and water is a natural glass cleaner. Vinegar naturally occurs through fermentation of juices, such as apple cider. Add 3 tablespoons of vinegar to a spray bottle and fill it with water. Shake well and use to clean the glass. You can soften the water with a little baking soda, which will react with the vinegar to make a stronger cleaning solution.
Alcohol and water makes a natural glass cleaner. Alcohol is naturally produced during fermentation as well. Alcohol alone will clean glass, but making a cleaner will make the alcohol last longer. Add 1/4 cup of alcohol to a spray bottle, then fill it with water. Mix well. Spray a generous amount on the glass and wipe clean with a lint-free cloth.
Water and Soap
you do not have these options available, simply use plain water, or add 2 drops of natural dish soap, such as Castile soap, to a spray bottle filled with water. Shake well and spray a liberal amount onto the glass surface. Wipe the glass clean and dry with a lint-free cloth.
