Grout can often discolour over time, turning black with mould or red with limescale, leaving the bathroom looking unsightly.

According to Molly Woodward-Moor at Stone Superstore, it’s important to never use “abrasive cleaners” as this will cause “damage”.

The expert told Mystudenthalls.com: “Avoid bleach or acidic cleaners on natural stone tiles like limestone, marble, travertine, or terracotta.

“These materials are porous and can be easily damaged.” If opting for bleach when cleaning other materials, it’s important to ventilate the area.

Molly added: “Never use harsh chemicals or lemon when cleaning tiles, as this can remove the sealant and cause damage to your tiles and grout.”

Whilst the high acidity in lemon juice can banish stains and discolouration, it’s important to know over time it can corrode the grout.

It’s also important to be mindful of the tool you are using when it comes to cleaning the bathroom.

The expert continued: “Avoid using abrasive materials such as scouring sponges or stiff bristle brushes, as these can scratch tiles and other surfaces and ruin their overall finish.

“Even the most durable of tile materials, such as ceramic and porcelain, should be treated with mild detergent and a microfibre cloth.”

Instead, the pro recommended a solution of warm water and washing-up liquid as a “reliable DIY alternative”.

Dilute it well and rinse thoroughly with warm water along with a microfibre cloth for effective cleaning.

Molly continued: “Grout is porous and can absorb dirt quicker than tiles, making them look dirtier than they are, particularly if you have light or white grout.

“Similarly to tiles, cleaners containing ammonia should be avoided at all costs as they are corrosive.

“This means they could weaken the grout, reducing its durability and leading to cracks.

“Whilst grout is notorious for a build-up of mould and mildew, a couple of cupboard essentials will do the trick.”

Britons can make their own grout cleaner with two parts baking soda and one part vinegar, if you haven’t already got these to hand, you can get them both for as little as £2.

“For the best results, use a soft bristle toothbrush to work in whilst the mixture is still bubbly and rinse with clean water.”

If you want to use bleach to clean because it is super affordable and can be picked up for around 40p, make sure to stick to cleaning the toilet with it or non-porous surfaces.
