Self-made sewer dredge with baking soda and white vinegar:

Prepare half a cup of white vinegar and half a cup of baking soda. Put enough water in the sink. Put the white vinegar and baking soda in. You will find that a large number of bubbles are produced in the pool like a chemical reaction. You can see that the sink is much cleaner, so it is really effortless to clean it.

Other ways to dredge the sewer:

1. There are oil stains, leftovers and vegetable stalks in the kitchen sink, which are easy to block the sewer. At this time, we can use Jianwei Xiaoshi tablets or effervescent tablets to solve the blockage problem. First put one in the outlet of the sink, and then use it to start flushing. If the blockage is serious, you can add a few more, and then use it all the time to start flushing, so that the sewer will be opened soon.

2. If only oil stains block the sewer, we can use washing powder to dredge it, pour the washing powder into the outlet of the pool, and then rinse it with hot water. After washing it several times, the oil stains can be washed clean, and the drainage will be smooth.

3. If you have a plastic soft straw at home, you can make it into a prop to dredge the water pipe. Use scissors to cut small mouths alternately on both sides of the straw wall to become a soft hook. Insert it into the drain, poke it back and forth, and you can take out your hair and sundries, so that the sewer will be open.
