Hard water occurs when an abundance of minerals are present in the water. Hard water is a common problem in many homes, and can leave surfaces -- such as shower doors, bathtubs, sinks, and faucet fixtures -- looking dull and dingy. There are a variety of cleaning chemicals designed to remove hard water residue and stains. However, these products contain harsh chemicals that can pollute your environment. Instead, use all-natural essential oils to remove hard water film from your home.
Fill a spray bottle with 1 cup water and 10 drops lemon essential oil. Gently swirl the bottle in a circular motion to mix the contents. Lemon oil is naturally acidic, and will cut through tough hard water grime.
Spray the mixture directly onto the hard water spot and let it sit for 30 seconds. Rub the surface clean with a cloth.
Continue rubbing and applying the mixture until you have removed the hard water spot. Wipe the surface clean with a dry cloth.
Prevent hard water spots and stains by drying shower doors, bathtubs, faucets, and sinks whenever they become wet.
