Hard water contains high concentrations of calcium and magnesium that deposit on bathtubs, shower doors, sinks and dishes to form lime scale. Faucets and showerheads clog with lime scale and can slow or even stop the flow of water. Lime scale will make your tub feel gritty and your coffee taste bitter. Don't spend money on expensive lime scale removers. The white vinegar you keep under your kitchen sink and the baking soda you keep in your cupboard act to dissolve and scrub away lime scale without introducing dangerous chemicals into your home.
Clogged Faucets and Showerheads
Fill a bowl with white vinegar.
Hold the bowl under the faucet or showerhead so it's completely immersed. If you can remove the showerhead or faucet, it would be easier than holding the bowl.
Soak the faucet or shower head for two to five minutes. Longer is better, but it may become difficult to hold the bowl. Remove the vinegar.
Dip a toothbrush in the vinegar and then into some baking soda.
Scrub the faucet or showerhead to remove any lime buildup. Reapply baking soda and vinegar to the toothbrush as needed.
Turn the water on for the faucet or showerhead to rinse.
Bathtub and Shower Door
Fill a spray bottle with white vinegar and thoroughly wet the surface.
Allow the surface to soak for five minutes.
Dip a scouring pad or brush into vinegar and then baking soda.
Scrub the surface to remove any lime buildup. Reapply the baking soda and vinegar to the scouring pad as necessary.
Rinse with running water, when possible, or with a clean washcloth soaked in water.
Small Surfaces, Dishes and Difficult Areas
Mix a paste of baking soda and white vinegar in a bowl.
Dip a washcloth into the paste and rub it on the metallic surfaces. Coat the surfaces thickly. This method will allow you to get into tight spaces around faucets and inside coffee pots.
Allow the paste to dry.
Scrub away the paste with another washcloth soaked in white vinegar.
Rinse with running water, when possible, or with a clean cloth soaked in water.
