How Do I Clean Tile Grout? VICTiles Tips & Tricks

If you’ve ever stood back after mopping your floor or wiping down the shower and thought why the grout still looks dirty, you’re not alone. Tile grout is notorious for trapping grime, soap scum and moisture, especially in high-use areas like bathrooms, laundries and kitchens.

At VICTiles, we get asked how to clean tile grout properly without damaging the tiles. The good news is with the right approach, a few handy tools and some preventative care, cleaning grout doesn’t have to be a chore you dread.

Below, we’ll walk you through practical, safe and effective ways to tackle stubborn grout stains, the tools that make the job easier, and how to protect your grout long-term. 

Why Does Tile Grout Get So Dirty?

Before we dive into cleaning grout, it helps to understand why grout discolours so easily. Grout is porous by nature, meaning it absorbs moisture, dirt and oils. In bathrooms, that often means soap residue and mould; in kitchens, grease and food splashes; and on floors, plain old foot traffic.

If grout isn’t sealed or the sealer has worn off, stains can settle in fast. That’s why a good grout cleaning routine paired with proper sealing helps to protect against common grouting mistakes, and makes all the difference.

Tackling Stubborn Stains and Discolouration

When tile grout has gone from light grey to something far less appealing, it’s time for a deeper clean. Depending on how dirty the grout is, you can choose from a few effective methods:

Dedicated grout cleaner

These are formulated to lift grime without damaging tiles or grout. Always follow the manufacturer’s instructions and spot-test first.

Bicarb-based paste

A paste made from bicarb soda and a gentle, pH-neutral cleaner is a popular DIY option. It’s mildly abrasive, which helps loosen dirt without being harsh.

Oxygen-based cleaners

These work well on organic stains like mould and general discolouration. They’re often safer than chlorine bleach and less aggressive on grout.

Avoid harsh acids or bleach

Products like vinegar or bleach can etch, dull or permanently damage stone surfaces. If you’re working with marble, travertine or limestone from our natural stones collection, stick to stone-safe cleaners only.

Step-by-Step: How to Clean Tile Grout

1. Apply your cleaner

Spray or spread the grout cleaner or bicarb paste directly onto the grout lines.

2. Allow dwell time

Let the product sit for 5–15 minutes. This gives it time to break down dirt and stains. Don’t let it dry out completely.

3. Scrub gently

Use a grout brush or small scrub brush to work the cleaner into the grout. Circular motions usually work best.

4. Rinse thoroughly

Wipe away residue with clean water and a microfibre cloth. Leftover cleaner can attract more dirt if not removed.

5. Dry the area

Drying helps prevent moisture from seeping back into the grout and reduces the risk of mould returning.

This process works well for general cleaning grout jobs and is especially effective for bathroom grout cleaning, where moisture build-up is common.

Tools That Make Grout Cleaning Easier

The right tools can turn grout cleaning from a back-breaking task into a manageable one. Must-have grout cleaning tools include:

• Grout brushes - Designed with narrow, stiff bristles to get deep into grout lines without scratching tiles.

• Small scrub brushes or old toothbrushes - Handy for tight corners and detailed areas like shower recesses.

• Microfibre cloths - Ideal for wiping away residue and polishing tiles once the grout is clean.

You’ll find many of these essentials in our tools and adhesives collection, perfect for DIY maintenance or professional results at home.

Steam Cleaners: Are They Worth It?

Steam cleaners can be a great option for some tiled areas. The high-temperature steam loosens dirt and kills bacteria without chemicals. They work best on sealed grout and glazed tiles.

However, steam cleaning isn’t suitable for all surfaces, particularly unsealed grout or certain natural stones, so always check compatibility first.

Sealing and Protecting Grout for the Long Term

Cleaning grout is only half the story. If you want those results to last, sealing is essential.

What Is Grout Sealer and Why Does It Help?

Grout sealer is a protective barrier that reduces how much moisture and dirt your grout absorbs. Sealed grout is easier to clean, resists staining and helps prevent mould growth which is especially important in bathrooms and wet areas.

When Should You Seal Grout?

• New grout: Newly installed grout should be sealed once it has fully cured, usually after a few days (check the grout manufacturer’s instructions).

• Existing grout: If water no longer beads on the grout surface, it’s time to reseal. Most grout needs resealing every 1–3 years, depending on usage and location.

Our range of grouts at VICTiles are designed to work seamlessly with quality sealers for long-lasting results.

How Sealing Makes Cleaning Easier

Once sealed, everyday spills sit on the surface instead of soaking in. This means:

• Less scrubbing during routine cleaning.

• Reduced risk of permanent stains.

• Better protection in wet areas like showers and splashbacks.

For joints around baths, vanities and wall-to-floor transitions, don’t forget flexible finishes like silicone, which help keep moisture out where grout isn’t suitable.

Choosing the Right Tiles Matters Too

High-quality tiles are easier to maintain and hold up better with regular cleaning. Whether you’re renovating or just planning ahead, explore our full range of tiles at VICTiles, to find options that suit your space and lifestyle.
