Grout plays a big role in how your tiled floors look, but it’s also the part that gets dirty the fastest. Over time, grout can turn dark, stained, or mouldy due to dirt, moisture, and daily foot traffic. The good news? With the right approach, you can bring your floor tiles back to life. In this guide, we’ll show you how to clean grout in floor tiles, from simple DIY methods to knowing when it’s time to call a professional.
Why Does Grout Get Dirty So Easily?
Grout is porous, which means it absorbs dirt, spills, grease, and moisture more than tiles do. Kitchens, bathrooms, and high-traffic areas are especially prone to grout discolouration if not cleaned regularly.
Step-by-Step: How to Clean Grout in Floor Tiles
1. Start With Basic Cleaning
Before using strong solutions, try a simple clean:
- Sweep or vacuum the floor
- Mop with warm water and mild detergent
- Let the grout dry so you can clearly see stained areas
This removes surface dirt and prepares the grout for deeper cleaning.
2. Baking Soda & Vinegar Method (DIY Favourite)
This is one of the most popular natural methods:
- Make a paste using baking soda and water
- Apply it directly to the grout lines
- Spray white vinegar over the paste
- Let it bubble and sit for 5–10 minutes
- Scrub gently with a grout brush or old toothbrush
- Rinse with clean water
✔ Great for light to moderate stains
3. Use a Grout Cleaner for Tough Stains
For heavily stained grout:
- Use a store-bought grout cleaner suitable for your tile type
- Follow the instructions carefully
- Avoid harsh chemicals on natural stone tiles
Always test on a small area first.
4. Scrub the Right Way
Use a soft or medium-bristle brush. Avoid metal brushes, as they can damage grout and scratch tiles. Scrub in circular motions for best results.
5. Dry the Area Completely
After cleaning, dry the grout thoroughly with a cloth or let it air dry. Moisture left behind can lead to mould growth.
How to Keep Grout Clean for Longer
- Clean spills quickly
- Mop floors regularly
- Use a pH-neutral cleaner
- Consider sealing grout to protect it from stains and moisture
Sealed grout stays cleaner and is much easier to maintain.
When Cleaning Isn’t Enough
If grout is:
- Cracked or damaged
- Permanently discoloured
- Growing mould repeatedly
Then cleaning may not be enough. In these cases, re-grouting or re-sealing is the best long-term solution.
