Bathroom sink clogs can be caused by a number of things, but one of the most common causes of bathroom sink clogs is a combination of dirt, hair, and skin flakes. Dirt and hair gets stuck to the soap scum in your drain and causes a clog. This then creates bacteria. That’s why when you pull out your drain stopper it has black slime all over it. If you run into a clogged bathroom sink drain, there are many ways to remedy it. You could use boiling water or use baking soda and vinegar.
