Grout may not be the star of your home’s interior, but it plays a vital role in the overall look of your floors, walls, and surfaces. Over time, though, grout between tiles tends to darken and stain, giving even the cleanest tiles a neglected look. That’s where steam cleaning comes in—a highly effective and eco-friendly method for restoring grout to its original appearance.
If you’re tired of scrubbing grout with limited success or harsh chemicals, this guide will walk you through how to clean grout with a steam cleaner, tips for optimal results, and answers to your questions about grout maintenance.

Why Use a Steam Cleaner for Grout?
Steam cleaners are celebrated for their ability to deep-clean surfaces without the need for harsh detergents. Here’s what makes steam cleaning a great choice for grout cleaning:
- Eco-Friendly: Steam cleaning eliminates the need for harsh chemicals, making it better for you, your family, and the planet.
- Kills Germs: Steam cleaners can reach temperatures high enough to kill bacteria, fungi, mold, and other pathogens.
- Deep Cleaning: The high-pressure steam effectively dissolves dirt and grime embedded deep within grout pores.
- Minimal Effort: The steam does most of the heavy lifting, saving you from back-breaking scrubbing.

How to Clean Grout with a Steam Cleaner
Step 1: Prep Your Work Area
Before you start steaming, prepare the area to ensure the best results.
Sweep and Mop the Floor
Remove dust, dirt, and surface debris from the tiled area. This ensures you’ll only be dealing with the grime embedded in the grout.
Test on a Small Area
Steam is powerful; it’s wise to test a small, inconspicuous area to make sure it won’t damage your grout or tiles.
Step 2: Gather Your Tools
You’ll need the following items for grout cleaning with a steam cleaner:
- A steam cleaner with a cleaning wand or grout-specific nozzle
- Clean microfiber cloths for wiping down
- A soft-bristle brush, optional for extra scrubbing (non-metal to avoid damaging grout)
Step 3: Set Up Your Steam Cleaner
Fill the Water Tank
Use distilled water to prevent mineral build-up in the steam cleaner. Never add chemicals or detergents; steam alone is effective for grout cleaning.
Attach a Grout Nozzle
Many steam cleaners include special attachments for cleaning grout. Attach the nozzle to focus the steam pressure directly on the grout lines.
Turn it On
Allow the steam cleaner to heat up according to the manufacturer’s instructions.
Step 4: Begin Steam Cleaning
Focus on Grout Lines
Start at one corner of the room and work your way across. Hold the steam nozzle directly over the grout line, moving slowly to allow the steam to penetrate and loosen dirt.
Use the Brush for Stubborn Stains
For tougher stains, gently scrub the grout with a soft-bristle brush immediately after steaming. Stains should lift away effortlessly.
Step 5: Wipe and Review
Immediately wipe the area clean with a microfiber cloth to remove loosened dirt and prevent residue from drying on the tile. Examine the grout and repeat the process as needed for areas with persistent stains.
Step 6: Final Rinse
Once you’ve steamed all the grout lines, perform a final rinse by wiping down the entire surface with a damp cloth. This ensures no residue is left behind.
Tips for Achieving the Best Results
To maintain bright, clean grout, follow these expert tips:
Choose the Right Steam Cleaner
Opt for a steam cleaner with a specialized nozzle for grout. Models that allow adjustable steam levels, such as the Dupray Neat or McCulloch MC1275, are ideal.
Work Slowly and Steadily
Rushing won’t help. Allow the steam cleaner enough time to penetrate and loosen dirt.
Clean Regularly
Set a consistent cleaning schedule to prevent dirt from becoming deeply embedded. Grout in high-traffic areas may need monthly cleaning, while other areas may do fine with quarterly maintenance.
Seal Your Grout
After cleaning, consider applying a grout sealer to protect it from future stains and moisture. Always allow grout to dry completely before sealing.
Is steam cleaning safe for all types of grout?
Steam cleaners are generally safe for most grout types, including cement-based and epoxy grout. However, always test a small area first, especially if your grout is old, fragile, or sealant-free.
How often should I steam clean grout?
It depends on the location and level of use:
- High-use areas (kitchens, bathrooms): Every 1–2 months
- Low-traffic areas (guest bathrooms): Every 3–4 months
Regularity ensures dirt doesn’t build up, saving you effort in the long run.
Can steam cleaning damage tiles or grout?
When used correctly, steam cleaners are safe and effective. However, excessive pressure or prolonged steaming in one spot can weaken grout, especially unsealed grout. Always follow the manufacturer’s recommendations for your steam cleaner.
Do I need professional help for steam cleaning grout?
Steam cleaning is straightforward and cost-effective for DIYers. However, for large-scale cleaning or severely damaged grout, consulting a professional may be beneficial.
Can steam cleaners remove mold from grout?
Yes! The high temperature of the steam kills mold and mildew, making it an excellent mold-removal tool for grout in damp spaces like bathrooms.
Maintain Your Grout and Keep It Looking Like New
Grout may not be the first thing you notice when you walk into a room, but its state can make a big difference in how clean and well-kept the space feels. Steam cleaning is not only one of the safest and most effective ways to clean grout but also requires minimal effort compared to scrubbing on hands and knees with chemical products.
For best results, establish a maintenance routine and choose the right tools for the job. With proper care, your grout can stay bright and spotless for years to come!
