How to Remove Hard Water Deposits from Grout

1. Use White Vinegar and Baking Soda

White vinegar is a natural acid that helps break down mineral deposits, while baking soda acts as a mild abrasive to lift stains.

Steps:

• Mix equal parts of white vinegar and warm water in a spray bottle.

• Spray the solution onto the affected grout lines and let it sit for about 10 minutes.

• Make a paste by mixing baking soda with a little water and apply it over the sprayed area.

• Scrub the grout gently with a toothbrush or grout brush.

• Rinse with warm water and wipe dry with a clean cloth.

2. Try Lemon Juice for a Natural Alternative

Lemon juice, like vinegar, contains natural acids that dissolve mineral deposits.

Steps:

• Squeeze fresh lemon juice directly onto the grout.

• Let it sit for 10–15 minutes to break down the hard water deposits.

• Scrub with a brush to lift the loosened buildup.

• Rinse and wipe the area dry.

3. Use a Commercial Calcium, Lime, and Rust Remover

If natural remedies don’t work, a commercial cleaner formulated to remove calcium and lime buildup can be highly effective.

Steps:

• Apply the cleaner to the grout following the manufacturer’s instructions.

• Allow it to sit for the recommended time.

• Scrub with a grout brush or an old toothbrush.

• Rinse thoroughly with water and dry with a clean cloth.

4. Make a Hydrogen Peroxide and Baking Soda Paste

Hydrogen peroxide is a great alternative for removing tough stains and brightening grout.

Steps:

• Mix hydrogen peroxide with baking soda to form a thick paste.

• Apply it to the grout and let it sit for 10–15 minutes.

• Scrub gently with a brush to break down mineral deposits.

• Rinse with warm water and wipe dry.

5. Prevent Future Hard Water Buildup

• Seal Your Grout: Apply a grout sealer to prevent water penetration and mineral buildup.

• Wipe Down Surfaces: After showers or cleaning, wipe down tiles and grout to remove excess water.

• Use a Water Softener: If hard water is a persistent problem, consider installing a water softener to reduce mineral content.
