Remove mould from tile and grout
Mold in tiles and grout
You will often see mold growing on the tiles in places like the bathroom or kitchen. The good news is that mold can be easily cleaned from non-porous tile surfaces.
How to remove mould from tile and grout
Start by rubbing the tiles and grout using a brush together with a household cleaning product or a specific matte product that kills mold. There are also commercial tile or grout cleaners that can be purchased.

After this, you will probably find that there are still mold stains left in the grout (it is known as the cement between the tiles ' joints). You can use bleach to make these spots disappear. Before using bleach, do a test to make sure the bleach does not discolor the tiles.
Don't forget to wear gloves to protect your hands from bleach.
Apply the bleach to the grout and let it rest for about 10 minutes. Instead of chlorine bleach you can use hydrogen peroxide if you want, or buy a product like the Oxyclean containing oxygen lye. If you have a septic system, it's better to use oxygen bleach than chlorine bleach.
Another alternative is to use baking soda. Mix with water to form a paste and then use a toothbrush to scrub in the grout.
If you find that the stains remain in the grout after bleaching, then repeat the process. Then rinse the chlorine with plenty of water.
If stains do not go away you can try using bleach-soaked paper towels. Wet the paper towels in bleach and then adhiérelas to the cement grout where the stains are located. Give it a little time and this should make the mildew stains disappear in the grout definitely.
Seal Cement Grout
Another thing you can do is apply a sealant to the cement grout. This will protect you from any small amount of mold remaining in the grout and also helps prevent mold from growing in the future.
Replacement of cement grout
You also have the option to completely replace the grout. First of all you will have to scrape the old grout. You can use a flat-blade screwdriver for this. You can buy new grout mixture from the hardware store and apply it yourself. Sealing the new grout with a cement grout sealant later will give you even more mildew protection.
