Toilet bathing near the surface of the tile, astringent, away from the bath far from the surface of the tile is still very smooth, ask how the matter, how to deal with
Calcium is deposited on the surface and scrubbed with acidic liquid.
Because the tiles when the tiles in advance in the water soak for a few hours in the water so that tiles can be filled with water can be particularly toilet tiles if the bubble time is short or no bubble tiles will absorb the surface of water and cement Inside the water surface color changes and then a long time easy to fall off is the case of friends
Too dirty, clean with detergent, wash powder is also OK ..
