First of all, we have to analyze the cause of dirty tiles. In addition to its extremely high gloss, hardness, rich colors and patterns, another important reason why ceramic tiles have been widely used is that everyone thinks it is very easy to clean and maintain. Daily cleaning only needs to mop the floor with water, no special maintenance, not afraid of scratching, not afraid of bumps.

And what I'm going to tell you is that this is a misunderstanding. First of all, tiles are also capillary, which means that if there is dirt on the surface, the next page will penetrate into the inside of the tile at a certain time. Secondly, tiles are also afraid of scratches.

Therefore, if we take a closer look at many newly renovated floor tiles, there are many subtle scratches, most of which are scratched by sand and metal during decoration, and these scratches will leave a hiding place for future stains. Finally, the abrasion resistance of tiles is limited. The wear resistance of different prices and different types of tiles is different, but even if it is a good quality tile, it will produce normal wear marks on the surface of the tile after a certain amount of normal stepping on the flow of people.

Therefore, most of the tiles at the entrance of some hotels, supermarkets, business halls and other public places are not as bright as the tiles inside, and they are not very clean.

To sum up, the dirty and blackened tiles we see now are just the appearance. In other words, the stains that make the tiles and floor tiles blacken are hidden deep inside. They either hide in scratches on the surface of the tiles or hide in the pores of the tiles.

That's why we can't get rid of it with regular cleaners.

Knowing the reason why the tiles and floor tiles are dirty and black, we can find the pathology of the disease, so it is time to prescribe the right medicine. Because conventional cleaners can only clean the stains on the surface of the tiles, and the stains on the inside can only be itchy through the boots. At present, there are many cleaners on the market that specialize in cleaning the inside of tiles and floor tiles, such as Amway, Shield King, Axianlu, 100 billion jubilee and so on.

One of the common features of these cleaners is that they are penetrating cleaners, which means that they can penetrate deep into the inside of tiles and floor tiles to clean stains. Of course, for some local stubborn stains, you can also try dilute hydrochloric acid, toilet cleaner, etc. to clean, but I generally do not recommend everyone to use these things, because the slightest accident will corrode the tiles and floor tiles, which will outweigh the losses.
