Tile and grout are the backbone of many beautiful bathroom, kitchen, and flooring designs — but keeping them clean is often easier said than done. Whether you’re working with porcelain, ceramic, or natural stone, improper cleaning techniques can damage surfaces, wear out grout, and even invite mould growth. To help you keep your tiled surfaces in top condition, we’ve compiled the top five tile and grout cleaning mistakes — and what to do instead.
Using Harsh Chemicals on Grout
Bleach and acidic cleaners may promise to make your tiles sparkle, but they can wreak havoc on grout. Harsh chemicals degrade grout over time, causing it to become brittle, crack, or discolour. This not only looks unsightly but also creates the perfect environment for mould and mildew.
Opt for pH-neutral cleaners specifically designed for tiles and grout. These are tough on dirt but gentle on your surfaces. A mix of baking soda and water also works wonders for a more natural solution.
Scrubbing with Abrasive Tools
It might be tempting to grab a steel wool pad or a hard-bristled brush when tackling grime, but using abrasive tools can scratch your tiles and erode the grout. This causes your tiles to look dull and aged far quicker than they should.
Use a soft-bristled brush or a microfibre cloth to clean tiles. For grout, a medium-bristle brush provides the right amount of pressure without causing damage.
Skipping Regular Cleaning
Letting dirt and grime build up over time doesn’t just affect appearances — it can also cause long-term damage. Grout is porous, which means it readily absorbs moisture, soap scum, and body oils if not regularly cleaned.
Make tile and grout cleaning part of your regular routine. A weekly wipe-down with a mild cleaner can prevent build-up and prolong the life of your tiled areas. And for a comprehensive guide on how to keep bathroom tiles mould-free, check out this practical resource from Tile Solution Australia.
Not Sealing Grout
Unsealed grout is like a sponge — it absorbs moisture and dirt easily, which can lead to staining and mould. Many homeowners don’t realise that grout needs to be resealed periodically to remain effective.
Seal your grout after installation and reapply sealant every 6–12 months, depending on foot traffic and water exposure. This provides a protective barrier and makes routine cleaning much easier.
Overwetting the Area
Too much water can seep into grout lines and under tiles, especially if they’re not properly sealed. This leads to mould growth beneath the surface, which can cause tiles to lift or even lead to structural issues.
When cleaning, use a damp mop or cloth — not a soaked one. Ensure the area is well ventilated and dries quickly. For bathrooms, using an exhaust fan and wiping down surfaces after use goes a long way in preventing moisture problems.
