Grout cleaning tips
1. Remove surface dirt & grime
The first thing you should do when faced with filthy shower grout is give it a good once-over.
Use 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 only the mould that's in the grout itself, which we're going to talk about tackling next.
2. Bleach it up
The next step is slightly more intricate but still shouldn't take too long. All you need is bleach and an old, hard-bristled toothbrush and you'll be ready to clean your grout. Pour 2 parts undiluted bleach into a small container, and add 1 part water. Ensure your rubber gloves are on and open all available windows to help ventilate the area. Dip the toothbrush into the bleach solution, then, beginning from up high, lightly 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.
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. This will help the bleach penetrate ever deeper into the grout, killing mould and removing any stains.
4. Rinse the shower thoroughly
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.
5. Give it time
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.
