This homemade remedy requires baking soda (also known as bicarbonate of soda or sodium bicarbonate), distilled white vinegar, a rag, and boiling water. For maximum effectiveness, do this when the shower won’t be needed for a few hours.
1.Pour half a cup of baking soda down the drain.
2.Follow this immediately with half a cup of distilled white vinegar, poured down very quickly.
3.Plug the drain with rag.(The combination of baking soda and vinegar will create a fizzing action, which should work away at the blockage.)
4.Leave it for at least 20 minutes, even a few hours.
5.Boil a kettle full of water, and pour this down the drain quickly, to flush away the blockage.
6.Repeat if needed.
