How to clean up the oil stains accumulated on the kitchen stove and the tiles next to it for a long time?

To remove oil stains from kitchen walls, try the following methods: pour hot thick batter soup or thick rice soup on the oil stains, or apply a thick layer with a brush. When it dries and peels off on the wall, the oil stains will stick to the wall. At this time, a light tear can remove oil stains. If it doesn't work once, you can come again several times.
