What should I do if the cracks of the floor tiles become black?

It has only been less than half a year since I moved into my new home. I found that many of the tiles in our house are blackened, especially the kitchen and bathroom. This makes the home ugly, and it also annoys me.
I found out on Baidu on the Internet that the reason for the blackening of the tile joints is: whether we are currently using white cement or the grout is made of inorganic materials and various pigments. The biggest disadvantage of inorganic materials is that they are not waterproof. When we wipe the wall and floor tiles, we will find that the tiles are wiped more cleanly, while the tile joints become darker and darker. The timely use of various specialized detergents will not help. Because the sewage has penetrated into the tiles.
So what should we do? What should I do if the cracks of the floor tiles become black?
I saw a beauty suture, and it feels pretty good. It is exquisitely made of a variety of high molecular polymers and high-grade pigments. Completely solve the troubles caused by white cement and caulking agent, and then apply it on it to form a very smooth clean surface, which is wear-resistant, waterproof, does not stain, and has excellent self-cleaning properties. Moreover, it is not easy to hide dirt, easy to clean, and clean with a single wipe. Its hardness and adhesion are very good. At that time, I saw it and it was pretty good, and I was holding the attitude of trying it. I didn't expect it to be quite satisfactory to me! This is how I used the effect picture of the beauty suture. Come take a look!
