Ever wondered why grout gets so dirty?

Tile grout, whether on floors or walls, often seems to have a mind of its own when it comes to attracting dirt and stains. So, why does it get so dirty?

February 5, 2024

It's porous!

It has tiny holes that love to suck up dirt and moisture like a sponge. This makes grout an excellent hiding spot for dust, mud, and other uninvited particles. As you walk on your tiled floor or splash water on the walls, these particles find their way into the grout, settling in for an extended stay.

Kitchen

The location of many a culinary masterpiece (and the occasional mishap!) are especially prone to grout drama. Spills and splatters, whether from spaghetti sauce or a rogue cup of coffee, can be magnets for grout stains. They can seep in and cause unsightly stains.

And the more foot traffic, the more dirt gets ground into the grout lines. Whether it's the soil from outside or just everyday dust, the hustle and bustle in your home can turn your grout into a dirt magnet.

Bathrooms

  • With their humid environments, bathrooms are perfect breeding grounds for mould and mildew – and your porous grout becomes a day spa for these unwanted guests. They not only make your grout look dirty, but also pose potential health risks.

  • Residues from soaps and hard water can accumulate on grout surfaces, forming a film layer that gradually alters its appearance.

  • Direct exposure to sunlight can lead to fading or a change in colour over time for grout.

Cleaning products

Sometimes, the products we use to clean our tiles might unintentionally contribute to grout grime. Harsh chemicals or improper cleaning techniques can strip away any sealant on the grout, making it more susceptible to dirt. It's like removing the shield that protects your grout from the dirt invaders.

It’s getting old

  • Over time, grout can wear down and lose its original lustre. As it ages, it becomes more prone to stains and discoloration. Regular maintenance and regular resealing can help prolong the life of your grout and keep it looking fresh.

  • If you've opted for a light-coloured grout, dirt or stains become more noticeable. Darker grout may hide the dirt better, but it's not immune!

What you can do:

  • Establish a regular cleaning schedule using mild, pH-neutral cleaners to ward off the accumulation of dirt and contaminants.

  • Make sure you have adequate ventilation in areas prone to high humidity, such as bathrooms and kitchens, to discourage the growth of mould and mildew.

  • Quickly clean up any spills to prevent liquids from penetrating grout lines.

  • Use soft brushes or cloths for grout cleaning, avoiding abrasive tools that may harm its surface.

  • Regularly examine grout for signs of discoloration or damage and take care of any issues quickly.

  • Consider using window coverings or UV-blocking films to shield grout from direct exposure to sunlight.

  • Professional cleaning and sealing can also help to delay the dirt!
