Fortunately, you can easily clean grout with the right approach and get it sparkling clean again. There are all sorts of products on the market, such as grout cleaner, to clean bathroom grout, but they often contain chemicals that can also damage the grout.

Supplies
Photo idea: Place all the supplies on a towel.
What do you need:
- Hydrogen peroxide (or vinegar) & baking soda
- Water in a plant sprayer
- Old toothbrush or grout brush
- Gloves
- Face mask (optional)
- Sponge and bucket
- If necessary: HG mould cleaner
Step 1: Make a safe cleaning mixture
Mix equal parts baking soda and hydrogen peroxide into a paste. This combination is powerful against dirt, yet gentle on your grout.
Tip : These ingredients are readily available at drugstores or supermarkets.
Step 2: Let it work
Apply the mixture liberally to the grout. Let it sit for 5 to 10 minutes to loosen the dirt. Grout under a bathtub can also be cleaned this way.
Waiting a bit in between? Perfect time to wipe down the shower screen !
Step 3: Brush away!
Use an old toothbrush or small scrub brush to thoroughly clean the grout. This will allow you to reach even the smallest pores in the grout.
Step 4: Rinse and admire
Wipe with a damp cloth and rinse the grout with clean water. You'll be amazed by the result: fresh, bright grout!
🚫 Don't: Use bleach or vinegar
While these products are powerful, they can damage your grout. Vinegar and bleach damage the grout, meaning you'll need new grout eventually.
Cleaning bathroom joints:
Safe alternative: Baking soda + hydrogen peroxide – just as effective and much safer and better for cleaning bathroom cement grout.
Bonus Tip: How to keep joints clean for longer
- Ventilate well: Install a bathroom fan to prevent mold.
- Weekly cleaning: Clean regularly with a mild sanitary cleaner.
- Quick brush routine: After showering, use a brush to immediately scrub away soap residue.
With this simple step-by-step plan, you can keep your grout fresh, clean, and mold-free. No bleach required—just a little attention and the right tools.
Prevent dirty dark joints in the shower and bathroom
Dirty bathroom grout—such as black mold or yellowish deposits—can be easily prevented with a few simple habits and tips. Here are the best ways to keep your grout fresh and clean:
Good ventilation is crucial
- Ensure adequate air circulation after each shower.
- Open the window or use a fan (at least 20 minutes).
- No window? A dehumidifier or automatic ventilation system can help prevent mold growth.
Dry the shower wall and floor after use
- Use a squeegee or towel to dry tiles and grout.
- Moisture often remains, especially in corners and at the bottom of the wall – dry that off too.
Weekly cleaning
- Clean the joints once a week with a mild all-purpose cleaner or a mixture of vinegar and water.
- This prevents mold and limescale from building up.
Use anti-fungal joint sealant
- If you ever re-apply or replace the grout, choose an anti-fungal (mildew) silicone sealant.
- These are specially designed for damp areas such as the shower.
Shower shorter and cooler (if possible)
- Less steam = less condensation = less mold formation.
- If possible, leave the door open after showering.
Use an anti-fungal spray
- There are sprays that you can apply after showering (such as HG mold preventer).
- These leave an invisible protective layer on the joints.
