A clogged up bath, sink, or shower drain, can occur when too much hair, gunk, or soap residue has accumulated in a drain pipe. When drains get clogged up, traditionally you have only a few choices: a plunger or drain snake that physically removes the clog, or some kind of caustic, toxic chemical like Drano. Even a plumber will either use a plunger, snake or chemical to clear your drain. You can unclog this clogged drain by using two things easily.
Hundreds of natural cleaning blog posts, books, and magazine columns recommend cleaning slow kitchen drains by pouring one cup of baking soda down the drain followed with one cup vinegar.
Simply mix a 1/2 of a cup of vinegar with a 1/2 of a cup of baking soda. Upon mixing it will fizz up, so pour it down the clogged drain ASAP. This bubbling mixture will dislodge the grime in the pipe drain. After pouring it down the drain leave it be for a few hours and then pour boiling hot water down to flush it out. You can also just dump the baking soda into the drain and then pour the vinegar down after it to let the fizz action happen initially in the drain.
