Keeping grout clean is essential for maintaining the beauty and hygiene of your home. Grout cleaner solutions and techniques vary, but using the right approach can make your tiles look as good as new. In this guide, we will share expert grout cleaning tips and tricks to help you achieve spotless tiles with minimal effort.
Why Does Grout Get Dirty?

Grout, being a porous material, absorbs dirt, grime, and moisture. Over time, this accumulation leads to discoloration and even mold growth. High-traffic areas such as kitchens and bathrooms are particularly prone to grout stains, making regular cleaning a necessity.
Best Grout Cleaner Tips for a Sparkling Home
1. Use a Homemade Grout Cleaner for an Eco-Friendly Approach
Instead of relying on harsh chemicals, you can create an effective DIY grout cleaner using ingredients you already have at home.
DIY Grout Cleaning Formula:
- Baking Soda and Vinegar: Mix equal parts of baking soda and white vinegar to create a paste. Apply it to the grout and let it sit for 10–15 minutes before scrubbing with a brush.
- Hydrogen Peroxide and Baking Soda: A mixture of hydrogen peroxide and baking soda works well for stubborn stains and kills bacteria.
- Lemon Juice and Baking Soda: Lemon juice not only cleans but also acts as a natural disinfectant.
2. Use a Steam Cleaner for Deep Cleaning
Steam cleaning is one of the most effective ways to remove deep-seated dirt from grout. The high-temperature steam penetrates the grout lines and lifts away grime without the need for harsh chemicals.
How to Use a Steam Cleaner on Grout:
- Fill the steam cleaner with water and let it heat up.
- Direct the steam nozzle along the grout lines.
- Use a small brush attachment to scrub away loosened dirt.
- Wipe with a clean cloth to remove any remaining residue.
3. Opt for Oxygen Bleach for Stubborn Stains
For grout that has turned dark or developed deep stains, oxygen bleach is a powerful cleaning agent. Mix oxygen bleach powder with warm water and let it sit on the grout for about 30 minutes before scrubbing.
4. Invest in a High-Quality Grout Brush
A grout brush with stiff bristles makes a significant difference in cleaning efficiency. Choose a brush with an ergonomic handle to reduce hand fatigue while scrubbing.
5. Seal the Grout After Cleaning
After deep cleaning, applying a grout sealer prevents future stains and moisture penetration. Sealing grout extends the time between cleanings and maintains its fresh appearance.
How to Seal Grout:
- Ensure the grout is completely dry before applying the sealer.
- Use a small brush or applicator bottle to apply the sealer along the grout lines.
- Let the sealer dry according to the manufacturer’s instructions.
- Wipe off excess sealer from tiles.
6. Regular Maintenance to Prevent Grout Discoloration
To avoid frequent deep cleaning, adopt these maintenance tips:
- Wipe down tiled surfaces after use.
- Use a pH-neutral cleaner for weekly maintenance.
- Avoid using too much water when mopping floors, as excess moisture can lead to mold growth.
- Dry grout lines after cleaning to prevent mildew formation.
Common Mistakes to Avoid When Cleaning Grout

1. Using Too Much Water
Excessive water can seep into grout and lead to mold growth. Always dry grout lines after cleaning.
2. Using Harsh Chemicals Too Frequently
Bleach and ammonia-based cleaners can weaken grout over time. Opt for gentler alternatives when possible.
3. Ignoring Grout Sealing
Skipping the sealing process after cleaning makes grout vulnerable to stains and dirt buildup.
4. Using a Metal Brush
A metal brush can erode grout, causing permanent damage. Stick to stiff nylon brushes.
