Tile floors sparkle. But grout? Not so much. Grout is a breeding ground. It stays damp and traps dirt. That makes it a safe space for microbes. Studies show bathroom grout often harbors just as many bacteria as shower floors, which can hold up to 60× more bacteria than the average toilet seat. No doubt, that’s a major reason you’re looking for how to clean grout between floor tiles.
The good news? You don’t need harsh chemicals or fancy tools to fix it. Just a few simple steps—and the right technique—will get your grout looking fresh again. Clean, quick, and without the stress.

How to Clean Grout Between Floor Tiles—Step-by-Step
This is where the magic happens. Let’s break down exactly how to clean grout between floor tiles—no fancy tools, no guesswork. Just simple, solid steps that bring dirty grout back to life.
🔹 Step 1: Apply Your Cleaner
Start with your cleaner of choice. If you’re using a store-bought grout cleaner, follow the label. For a DIY mix, try baking soda and water for a paste, or equal parts vinegar and warm water for a spray.
Spray or spread it straight onto the grout lines. Get it into every groove. Don’t just splash and hope—it needs to cover well. Be generous but neat. And don’t forget the corners—they collect the most grime.
Let it sit for a minute while it starts to break down the dirt.
🔹 Step 2: Let It Sit (and Do Its Thing)
Now wait. Let the cleaner work for at least 5 to 10 minutes. That’s key. Rushing this step is where most people mess up. During this time, the solution loosens up deep-set dirt and any greasy stuff hiding in the pores. If you’re using a natural mix, this sit time matters even more—natural cleaners work slower but are just as effective when given time.
Need to hit a bigger area? Clean in sections so nothing dries out too soon.
🔹 Step 3: Scrub the Grout Lines
Now for the elbow grease. Grab your grout brush or old toothbrush and start scrubbing. Use small, circular motions and focus on one line at a time. Apply steady pressure—but not too much. Let the brush do the work. If your cleaner starts to dry, spritz again as you go. You’ll notice the dirt lifting as the grout lightens up.
Want a tip? Wipe as you go to keep dirt from resettling into cleaned areas.
🔹 Step 4: Wipe It All Clean
Once the scrubbing is done, it’s time to wipe everything down. Use a damp microfiber cloth to lift the grime and any leftover cleaner. Be thorough here. Any residue left behind can make grout look cloudy—even if it’s technically clean. If needed, go over the area twice. You can also mop with warm water for larger spaces; just don’t flood it.
If some spots still look stained, don’t stress—we’ll tackle that next.
🔹 Step 5: Dry It Out Completely
Last step, but don’t skip it! Use a clean, dry cloth to blot and dry the grout lines. Leaving moisture behind—even clean water—can pull new dirt in fast. Open windows or turn on a fan if you’re in a bathroom. Dry grout stays cleaner longer, so take the extra minute here. This also helps you see if you missed a spot so that you can catch it early.
What to Do If Nothing’s Working
Scrubbed your heart out, and the grout still looks grimy? Don’t panic—it happens. Some stains go deep. Real deep. Especially in high-traffic spots like kitchens and bathrooms.
First, try going over the area again with a fresh round of cleaner. But this time, let it sit longer—10 to 15 minutes. Then scrub a little harder, using a stiffer brush. You’ll be surprised what a second round can lift. Still not budging? This is where heat can help. A lot of people now steam clean grout, and for good reason. Steam breaks down gunk that scrubbing can’t reach. It also kills bacteria without harsh chemicals. Just aim the nozzle at the grout lines, move slowly, and wipe away the loosened grime with a clean cloth.
No steamer? Don’t worry. Many hardware stores rent them. Or ask a neighbor—you never know who’s got one collecting dust. If all else fails, you may be dealing with stained, unsealed grout. In that case, it might be time to reseal—or in extreme cases, re-grout. But that’s rarely needed if you catch it early and clean it right.
How to Keep Grout Looking Like New
Clean grout feels amazing. But how do you keep it that way? Here’s the secret: a few small habits go a long way. And none of them takes more than a few minutes.
Start with a weekly wipe-down. Just a damp microfiber cloth is enough. Pay attention to areas that see the most foot traffic. Dirt builds fast, especially in kitchens and entryways. Quick wipes stop it from sinking in.
Next, clean up spills immediately. Grout is like a sponge. The longer liquids sit, the deeper they go. Especially if your grout isn’t sealed. Coffee, juice, grease—they all love sticking around. Use the right floor cleaner. Harsh or oily products leave residue that attracts even more dirt. Stick to pH-neutral cleaners made for tile floors. Your grout will thank you.
Thinking long-term? Seal your grout. Sealed grout repels stains and makes cleaning way easier. If your grout hasn’t been sealed in a while, consider doing it after your next deep clean. Most sealers last one to two years. Want to stay ahead of dirt year-round? Don’t miss our Floor Care Tips for Fall 🍂—your floors will thank you!
Finally, avoid bleach. It may whiten grout short-term, but it weakens it over time. Go gentle and stay consistent. That’s how clean grout stays clean.
Conclusion: Grout That Looks Brand New
