You most likely already have these items in your home, so this is a perfect cheap solution to your clogged drain problem! All you will need is baking soda, vinegar, and hot water. First remove the stopper or strainer from the drain, then remove any hair or excess scum from around the drain. Pour boiling water down the drain, next pour in about a cup of baking soda, followed by an equal amount of vinegar. You will start to see the mixture begin to fizz immediately. This fizzing action is what helps remove the clog from the pipe. Let it sit for 30 minutes to an hour, or leave it overnight. Finally wash it down with boiling water and the drain should now be unclogged.
