How to get rid of bad smell from the kitchen sink pipes
What you need
2 liters of water
400ml of white vinegar (2 cups)
90gr of baking soda (1/2 cup)
A big bowl
Steps
Put 1 liter of water into the bowl
Put the vinegar in the bowl and mix
Add the baking soda to the bowl and just as the foam forms pour it all down the drain of the kitchen sink.
It doesn't matter if some of the baking soda is still in the bowl as far as I'm aware.
After 1 hour pour a liter of boiling water down the drain and that's it!
