How to clean the grout in your shower – the results are AMAZING!

How to clean the grout in your shower

The whole purpose of showering is to come out looking and feeling clean. If your grout is mouldy, you’ll barely want to get in, let alone feel sanitised after the experience.

Although black mould and pink mildew can seem daunting, it’s often much easier to clean then you think.

To prove this to you, we took on the challenge of cleaning up a truly filthy shower, with blackened grout, mildew stains and even living, fluffy mould! Yes, it was truly disgusting.

How to clean grout in the shower

Now we’ve got that elephant in the room out the way, it’s time to get down to business.

1. Clean grout thoroughly to remove surface dirt & grime

The first thing you should do when faced with filthy shower grout, is give it a good, thorough scrubbing.

We used limescale remover spray, and the rough side of a sponge with lots of fairy liquid.

This will remove the surface dirt, living mould and leave you with the moul stains, which we’re going to talk about tackling next.

Although this isn’t a particularly pleasant task (rubber gloves are advised!) you’ll see an immediate improvement in the appearance of your grout.

2. How to clean grout using bleach

The next step is slightly more intricate, but still shouldn’t take too long. All you need is bleach, an old, hard bristled toothbrush, and you’re ready to clean your grout.

Ready to get started?

Pour 2 parts undiluted bleach into a small container, and add 1 parts water. Ensure your rubber gloves are on, and open any windows if possible.

Dip the toothbrush into the bleach solution, then, beginning from up high, scrub the grout with the brush. Go over each section of grout thoroughly so that the bleach seeps deep into the grout.

Once you’ve covered the entire area, leave to sit for 30 minutes.

So much whiter!

3. Scrub your grout once more

In order to really remove those blackened grout stains, you want to scrub the grout for a second time. There’s no need to add any more bleach, a damp toothbrush will do.

4. Wash the grout & shower thoroughly to remove bleach

While amazing at cleaning, bleach isn’t particularly skin-friendly. To ensure nobody suffers from any irritation during their next bath or shower, it’s extremely important to wash the solution away thoroughly.

Wet the entire shower with the shower head, and use the rough side of the sponge to remove bleach residue. Use lots of water to ensure the tiles and bathtub are completely clean.

I think we can safely say this shower has been transformed.

If your grout is still looking grimier than you’d like, be patient. Over the next few hours, the grout will continue to whiten until it really does become completely transformed.

How to maintain your grout

In order to prevent such a bad build up of mould in the future, we advise treating grout with bleach every couple of months and cleaning normally once a week.

Here’s to stepping out the shower feeling clean from now on!

Wow! The difference in that filthy grout is seriously amazing. Will you be trying this method?

    Bleach and elbow grease, who knew! The terms “Grandmother” and “sucking eggs” comes to mind. I put an old non-slip bathmat in the bottom of the shower tray and plastic bags on my feet while doing this job, otherwise you are inclined to ruin your footwear or get bleach on your bare feet when it runs down the wall.
