Unless you deliberately chose a dark colour, you should be concerned if your grout lines look black. This usually indicates mould or mildew growth, which is hazardous to your health.

You can prevent this from happening, but things can happen despite our best efforts! If you’ve noticed dark grout stains, then you just have to clean them up.

 

How to clean grout that has turned black? Here are some infallible natural methods that make the grout white and clean again.

 

Baking soda to whiten grout

Baking soda is an excellent ingredient for removing dirt from grout and whitening it completely. This natural and economical substance is widely used in household chores due to its effectiveness.

 
 

Suitable for not scratching the tiles and for thoroughly degreasing them and making the grout white again, here’s how to use it:

– Mix baking soda and hot water until you get a thick solution
– Apply the mixture to the joints and leave to act for approximately 30 minutes
– Scrub vigorously with an old hard-bristled toothbrush
– Remove dirt with a clean, wet microfiber rag

Thanks to the abrasive action of the toothbrush , bicarbonate acts on the joints, removing even the most stubborn grease stains, and even the black ones that form in the shower tiles.

Vinegar to clean shower joints

 

Another valid alternative for removing dirt from shower tile joints is white vinegar. Here’s how to use it:

 

– Prepare a solution with vinegar and warm water
– Pour the liquid into a nebulizer and spray directly on the areas to be treated
– Leave to act for 10/15 minutes
– Rinse with a damp cloth

The compound can also be used effectively against mold and any type of dirt that has nestled between the bathroom tile joints.

Clean the joints with potato starch

Effective against black grout, potato starch also acts against the most stubborn dirt. To prepare a perfect solution to remove blackness you need to mix 1 tablespoon of starch with 1 liter of warm water and put the mixture in a spray container .

 

Spray the product obtained between the joints, leave to act for about half an hour and then remove the encrusted dirt with a clean, damp cloth.

Hydrogen peroxide for encrusted joints

Excellent for encrusted joints , 130 volume hydrogen peroxide is another natural method for eliminating even the most stubborn and hardened dirt that accumulates in the spaces of the tiles. You can easily find hydrogen peroxide in household goods stores or at the hardware store and use it to clean grout.

 

The solution to obtain a better result is to pour it directly onto the joints and scrub with a toothbrush, acting on the dirt. Before using hydrogen peroxide, since it is a very strong substance, you must always remember to wear rubber gloves to protect the skin of your hands from irritation and inflammation.

Also, after using the product, ventilate the room for some time, so that the persistent odor goes away. If the result is not satisfactory with this method, add some potato starch to the hydrogen peroxide, respecting the proportions of three tablespoons of potato starch in a glass of hydrogen peroxide.

 

Pour the solution obtained onto the joints and leave to act for 1 hour. Remove everything with a wet microfibre cloth, the joints will be very white.
