Knowing how to clean tile grout is a key skill to add to your cleaning arsenal, whether you’re tackling bathroom tiles, floor tiles or kitchen wall tiles. Not only is dirty grout unhygienic and potentially bad for your health, but it can ruin the look of a room, too, so it’s important to make cleaning tiles part of your regular cleaning schedule.

Clean tile grout before you move on to cleaning tiles. The dirt from the grouting will probably get onto the tiles, so you can wipe it all clean afterwards.

Find out all you need to know about how to clean tile grout in this guide.


Do you know those little black spots that keep appearing on your tile grout? That’s mildew – and spores from it are pretty easily released into the rest of the room. And take it from us, you don’t want to be breathing them in – especially if you suffer from conditions such as asthma already. So, knowing how to clean tile grout isn’t just about caring for your bathroom or kitchen’s looks, it’s about your health, too.

  1. HOW TO CLEAN TILE GROUT WITH BLEACH – If you’re using a heavier chemical cleaner, such as bleach, to clean tile grout, always open the windows to minimise fumes, and take care over what products you’re using together. There are various ways of doing this. You can pour a little neat bleach into a cup then take an old toothbrush, dip it in and apply it to the grout. Or you can mix bleach with some baking soda/bicarbonate of soda to make a paste (think toothpaste consistency); apply it to the grout, leave for 15 minutes then take the brush to the grout and scrub at it to work away from the grime. Finally, rinse with a shower head or wet cloth and allow the grout to dry fully before deciding if you need to take another run at it.
  2. BEST HOMEMADE GROUT CLEANER – Rather not use harsh chemicals? The easiest way to get tile grout looking as good as new using a homemade grout cleaner is by simply mixing baking soda and white vinegar in a bowl until thick paste forms. Work the paste between the tiles into the grouting with an old toothbrush. Leave the solution to work its magic for 30 minutes, then rinse off with clean water and wipe any residue with a soft microfibre cloth. Repeat as necessary if your grouting isn’t sparkling clean straight away.
  3. HOW TO CLEAN GROUT IN A SHOWER – Cleaning grout in a shower can be particularly tricky, not least because it sees the biggest build-up of grime. Run a hot shower with the door and windows closed for a few minutes before you start cleaning. Then use one of the methods above, but swap the toothbrush for a small, soft material like cotton wool or cotton buds to get the bleach or baking soda mixture into the grouting in the corners of the shower. Wiping down walls after your shower with a clean, dry cloth can help limit the grime and mould that water encourages. Pay special attention to those corners, as well as the bottom of the wall, to avoid a build-up of water. And, ensure the room is well ventilated: reducing condensation in the room by opening windows or running an extractor fan will actively discourage more mould appearing.
  4. USING A GROUT PEN – If, once you’ve cleaned your tile grout, it still looks unsatisfyingly yellow or grey, take a grout pen to it (the next best thing to hacking out the old grout and regrouting). It won’t clean your tiles and it won’t last forever but it will brighten the tile grout for some time. These pens usually have anti-fungal properties so they’ll discourage mould growth, too.

  • While vinegar alone can be too aggressive on grout, when you mix it with Dawn, you’ll dilute some of that harshness while still maintaining its cleaning qualities. To ensure the soap and the vinegar mix thoroughly, heat the vinegar for a minute in the microwave before combining with soap. Apply using a spray bottle and scrub away. As mentioned, bleach is very powerful but you have to use it with caution on tile grout. It can also bleach out tiles, depending on the tile material. So only use it sparingly once a month is plenty and dilute it with water before applying. A note: Bleach cleaning won’t last as long on shower tiles because every time you run the shower, the water will wear away the effects of the bleach. Use it in spaces that don’t get a daily soak.
