Not all products are good for dealing with blockages in the bathroom.
A combination of vinegar and baking soda may help clear a clog in the kitchen, but it won't do much good in the bathroom.
Plumber Justin Cornforth told The Mirror how to effectively deal with blockages in the bathroom.

Hair is the most common cause of clogs here. Baking soda and vinegar are useless here.
In this case, a mechanical rather than a chemical method is more effective.
A drainage snake will help free the pipes from hair. It effectively catches hair and perfectly clears the path.
Using a drainage snake, you can thoroughly clean the pipes in your bathroom.
But the expert advises choosing a tool made of quality materials. A plastic zipper can break, which will only add to the problems.
A flexible, but at the same time durable tool is needed, the plumber emphasized.
