Even if your porcelain tiles are installed with a minimum grout line (typically 2mm) there will be a grout line visible. You might have to get up to close to see it, but it will be there. This is because jointless installation is not the best practice. Grout helps keep dirt from getting underneath your tiles and adds strength to the installation.
Even if you have the tiniest of grout lines your porcelain tile installation can still be susceptible to discoloured grout. Made from a mixture of water, cement and sand, grout is porous. This means grout is prone to staining due to mould or mildew. Given that your bathroom is wet and steamy, this can’t be avoided.
However, this doesn’t mean that you have to live with discoloured grout. There are countless products and more natural methods to banish the stains and get your bathroom gleaming again.
Cleaning grout with bicarbonate of soda
For this method, you will need an old toothbrush, bicarbonate of soda and vinegar. It’s very easy, simply mix the bicarbonate with water to form a paste. Rub this paste into the grout lines using the old toothbrush.
Next, pop some vinegar in a spray bottle and distribute it over the bicarb laden grout lines. You will notice the paste starts to bubble up. Get back to work with your toothbrush, scrub away at the grout lines and rinse well with water. You should be left with dazzling white grout lines.
Mrs Hinch grout cleaner
Cleaning influencer Mrs Hinch has taken social media by storm with her tips and tricks for the perfect home. Armed with a SonicScrubber and pot of The Pink Stuff, Mrs Hinch showed her viewers via Instagram how she tackled her discoloured grout.
The Pink Stuff is dubbed ‘the miracle cleaning paste’ and is championed for being 99% natural ingredients and non-toxic. Mrs Hinch dipped her SonicScrubber into the paste before getting to work on the grout. The SonicScrubber is not unlike an electric toothbrush but comes with different interchangeable heads for different cleaning tasks.
It’s simply a case of rinsing with water and marvelling at the colour difference.
Is grout eraser effective?
Whilst a little more expensive, grout erasers are a quick way to remove grout dirt without too much elbow grease. The JML Doktor Power Magic Eraser is a huge hit and a go to product for many. You don’t need any detergent, simply add water to the eraser and get to work on cleaning your grout. It can also be used for stubborn marks and stains on taps, tiles, baths and sinks.
Remove mould from grout
There are a number of products on the market to help you if mould has affected your tile grout. Mould isn’t the end of the world and certainly doesn’t mean your bathroom is unhygienic, it just happens when moisture is present. The HG Mould Spray is an incredible product. You simply spray on the affected areas, leave for the allotted time, and remove with warm water and a cloth. It is best to do this before the mould gets out of hand.
For tougher stains, the UniBond Anti Mould Grout Pen is a popular tool. Whilst it doesn’t get rid of stubborn mould it allows you to put a fresh white coat over your grout to leave it looking as good as new.
White vinegar spray
A great way to prevent mould or discolouration is to treat your grout with white vinegar spray. You can buy a readymade solution or make your own at home. You will simply need to mix water and white vinegar in equal parts in a spray bottle. Simply use the solution a few times a week on your tiles and it should be enough to keep any issues from arising. Just make sure to use white vinegar and not the sort you put on your dinner, or your bathroom could end up smelling like a chip shop.
