You remember that satisfaction of having just cleaned your kitchen or bathroom, the countertops glimmer, the tiles shine. And yet there’s still something that looks filthy. And then it dawns on you: the grout. Those little strips of area between the tiles that appear to draw every spill, every stain, and every speck of dirt on its own over time. It is the same as having a sharp suit with scuffed shoes regardless of how sharp the suit is, dirty grout takes away from the appearance.
Grout is the unsung hero of the tile surface. It keeps everything held together, literally, and isn’t seen until it’s filthy, stained, and covered with mold. Why does it stain so much? Because grout is porous, and therefore, it will suck up moisture, dirt, oils, soap scum, and whatever else crosses its path.
Let us think of grout as lines of comic strips. They ink them, they tell the story, but when they spread out or wipe off totally, the entire story goes crooked.
The bad news: you can’t just sort of just employ strong chemicals or one large machine to restore grout. There are low-cost, easy-to-do techniques, some of which require things you most likely have at home, that will have grout looking new. And something that will surprise you: if grout isn’t constantly cleaned, it can contain 200,000 bacteria per square inch. More than a toilet.
So let’s do it.
In this article, 7 simple, effective, and downright satisfying grout cleaning shortcuts are revealed. From bathroom mildew to kitchen grease, and those yucky stains, these shortcuts will leave your grout looking and feeling like new.
Learning About Grout
A quick rundown of what grout is and why it’s so dirty before we get into the shortcuts.
Grout is cement and it’s in the gaps of tile. It’s durable and hard but permeable. Also means it’s going to want to pull dust, water, and soil out of the environment eventually. And, based on where the grout sits (bathroom counter tops, kitchen floors, shower walls), may become a bacterial/mold/mildew growth petri dish.
Most commonly culprits to discolor grout include below:
-Mold and mildew: Flourish in damp, poorly ventilated spaces like bathrooms.
-Soap scum and hard water: Leave deposits and film.
-Dirt, grease, and spills: Make themselves readily available in kitchens and entrances.
This lets you know how to choose the proper cleaning technique based on what kind of grime you’re dealing with. Now, onto the good stuff, of the hacks.
The 7 Powerful Grout Cleaning Hacks
1. Baking Soda + Vinegar
The fizz that fights grime
This is a natural cleaner fan favorite, and it’s absolute magic on moderately dirty grout.
How it works:
The fizzing reaction that occurs when baking soda and vinegar combine breaks down grime and assists in pushing it out of grout lines. It’s particularly well-suited for bathrooms and light buildup.
Steps:
Apply baking soda directly to dry grout lines.
Spray white vinegar from a spray bottle over the baking soda.
Let the fizz bubble for 5–10 minutes.
Scrub with a toothbrush or grout brush.
Rinse and dry.
Best for: Back splashes, bathroom tile, and daily maintenance.
2. Hydrogen Peroxide + Baking Soda
Whiten and disinfect without bleach
Ready to say goodbye to mold and get the light back? Use this combo.
How it works
Hydrogen peroxide is a germicide and stain remover. With baking soda, it forms a gritty whitening paste.
Steps
Combine 1 part hydrogen peroxide and 2 parts baking soda to make a paste.
Apply with brush or gloved finger to grout.
Let sit for 10–15 minutes.
Clean thoroughly.
Rinse and shine.
Works best on: Shower grout, mildew discoloration, and stained areas.
3. Lemon Juice + Borax
Citrus freshness with disinfecting strength
If you want an all-natural cleaner that has a citrus scent, this is the ticket and is environmentally friendly.
How it works
Lemon juice acid also dissolves deposits, and borax kills mildew and stink.
Steps:
Pour borax powder down grout lines.
Soak with lemon juice to activate borax.
Let sit for 10 minutes.
Wash and rinse very well.
Best for: Doorways, kitchen floor, and stinky-smelling areas.
4. Steam Cleaner
Cleaning deep with only water
A steam cleaner operates with high-pressure heat that chemically free dissolves grime and germs kills.
How it works
Hot steam water seeps into grout pores, pushing out grime and killing microbes with heat.
Steps:
Use a portable steam cleaner with a grout nozzle.
Steam slowly across grout lines.
Blot loosened grime with cloth.
Best for: Large tile floors, tight corners, and green cleaning.
Tip: Test first, some grout will not accept high heat.
5. Oxygen Bleach
Heavy-duty cleaning without gross fumes
If your grout is extremely stained, oxygen bleach is a powerful but gentle solution.
How it works
It emits oxygen ions that capture dirt and organic material. It’s gentler on color than chlorine bleach and will not release toxic fumes.
Steps:
Combine oxygen bleach with warm water.
Pour over grout and allow to sit for 10–15 minutes.
Scrub and rinse.
Best for: Stained grout, high-traffic floors, and deep cleaning.
6. Toothbrush + Dish Soap
Easy, quick, effective
You sometimes need a quick solution. This is ideal for weekly cleaning.
How it works:
Dish soap dissolves grime and grease, and a toothbrush reaches tight spaces slowly but surely.
Steps:
Add a few drops of dish soap to warm water.
Insert a toothbrush into the solution.
Scrub grout lines and rinse.
Best for: Kitchen and bathroom maintenance cleaning.
7. Drill Brush
Power scrubbing for big jobs
If you’re dealing with large areas or tough grime, a drill brush attachment saves serious effort and time.
How it works:
The powered brush provides smooth, uniform, high-speed scrub pressure that easily draws dirt out of grout.
Instructions:
Equip your power drill with a grout brush head.
Work in with your desired cleaner (i.e., paste of baking soda).
Clean with the drill.
Rinse and blot dry.
Best for: Large tiled flooring, business offices, or where serious grout restoration is needed.
Tips for Grout Maintenance
Get your grout clean with ease
Once you’ve restored your grout, a little routine maintenance will go a long way. Here’s how to keep it looking sharp:
Seal your grout every 6–12 months to protect it from stains and moisture.
Wipe down wet surfaces like shower walls after use.
Clean spills immediately to avoid staining.
Use mild cleaners that won’t degrade the grout over time.
Ventilate humid areas with fans or open windows.
Sweep or vacuum first, and then clean, so dirt isn’t pushed into grout lines.
These practices as oral care: brush once a day, and you will never need a root canal.
