If your bathroom or kitchen drain is clogged, you don’t actually need to buy an expensive, toxic drain cleaner at the supermarket or hardware store. There’s a tried and true home remedy for clearing drains, whose primary ingredients you almost certainly have around the house anyway: baking powder and salt.
¾ cup baking powder
¾ cup salt
⅔ cup warm vinegar
Stir the baking powder and salt until they’re mixed well.
Pour the mixture into the clogged drain.
In order to measure it out better, try filling an unused sugar dispenser with the mix, or sticking a small funnel into the drain in question.
Now pour the warm vinegar in…
Now the blockage should be clear and the sink will drain again properly. With this homemade solution you can both save money and avoid noxious chemicals — your drain will thank you and so will the environment! Source
