Although the kitchen is a place where delicious food is produced, it is also the hardest hit by oil pollution. Kitchen tiles can't escape the invasion of oil stains and stains, and how to completely remove these stubborn stains has become the trouble of housewives.

1. Brick joints on the floor: A lot of oil stains often accumulate in the brick joints on the kitchen floor. When cleaning, the diluted hydrochloric acid can be dripped on the brick joints, and then many small bubbles will emerge from the hydrochloric acid. After a few seconds, brush gently along the brick seam, and the dirt in the brick seam will be easily removed. Finally, rinse the ground with clear water.

2. Tile cleaning: Oil stains accumulated on kitchen tiles can be wiped off with leftover bread. Because bread is soft, sticky and contains a lot of starch, it is easy to absorb oil stains. This method is not only simple but also environmentally friendly.

3. Moldy spots on ceramic tiles: It is difficult to clean the joints of ceramic tiles on kitchen walls, and it is easy to grow moldy spots due to oil accumulation. But it doesn't matter, an old toothbrush and some alcohol can easily remove the mildew spots.
