Soap scum on granite countertops can be unsightly. Fortunately, removing it doesn't require harsh chemicals. This guide offers safe and effective methods to restore your granite's shine.

Understanding Granite & Soap Scum

Granite is a porous natural stone. Soap scum, a residue of soap and minerals in hard water, clings to its surface. Ignoring it can lead to staining and dullness. Regular cleaning prevents buildup.

What You'll Need

Before you begin, gather these simple supplies:

Microfiber cloths: These are gentle on granite and highly absorbent.
Warm water: This is your primary cleaning agent.
Mild dish soap: Choose a non-abrasive soap.
White vinegar: A natural cleaner that helps cut through soap scum.
Baking soda: A gentle abrasive for stubborn stains (use sparingly).
Spray bottle: For easy application of cleaning solutions.
Soft-bristled brush: For scrubbing delicate areas.

Step-by-Step Cleaning Process

1. Prepare the Surface

Clear the countertop of any items. Pre-clean loose debris with a damp microfiber cloth. This prevents spreading soap scum.

2. Warm Water & Soap Solution

Mix a small amount of mild dish soap into warm water. Dip a microfiber cloth into the solution and wring it out well. Excess water can damage the sealant.

3. Gentle Scrubbing

Wipe the soap scum-affected areas with the damp cloth. Use a soft-bristled brush for stubborn spots or crevices. Avoid harsh scrubbing, which can scratch the granite.

4. Rinse and Dry

Thoroughly rinse the surface with clean, warm water using a fresh microfiber cloth. Immediately dry the granite completely with a clean, dry microfiber cloth. Leaving moisture can damage the sealant.

5. Vinegar Treatment (For Stubborn Scum)

If soap scum persists, create a 50/50 solution of white vinegar and water in a spray bottle. Spray the solution onto the affected areas. Let it sit for a few minutes before gently scrubbing. Rinse and dry thoroughly.

6. Baking Soda Paste (For Extremely Stubborn Scum)

As a last resort for extremely stubborn soap scum, make a paste of baking soda and water. Apply a small amount to the affected area, gently scrub with a soft cloth or brush, rinse, and dry immediately. Avoid leaving the paste on for extended periods.

Preventing Future Soap Scum Buildup

Regular Cleaning: Wipe down your granite countertops daily with a damp cloth to prevent soap scum buildup.
Proper Ventilation: Ensure adequate ventilation in your bathroom to reduce moisture buildup.
Immediate Clean-up: Clean up spills and soap residue immediately to avoid setting stains.
Resealing: Periodically reseal your granite countertops to maintain their protective layer and prevent staining. Consult a stone professional for advice on resealing frequency.

What NOT to Do

Avoid abrasive cleaners: These can scratch and damage the granite's polished surface.
Don't use bleach: Bleach can damage the sealant and discolor the stone.
Don't let water sit: Immediately dry any spills or cleaning solutions to prevent water damage.

Maintaining Your Granite's Beauty

Following these steps will keep your granite countertops sparkling and free from unsightly soap scum. Remember, prevention is key! Regular cleaning and proper maintenance will protect your investment and preserve your granite's natural beauty for years to come. If you're unsure about any cleaning method, consult a professional stone cleaner for guidance.
