There are often oil stains and leftovers in the kitchen pool, which cannot be removed once the water is blocked. At this time, as long as you throw a few Jianweixiaoshi tablets or vitamin effervescent tablets, you can solve the congestion problem. First, put a tablet into the water outlet of the sink, and then rinse it with boiling water. If congestion is serious, add a few more tablets, scald them with boiling water several times repeatedly, and then drain them smoothly.
