What's the best way to clean a clogged drain?
assistant
The best way to unclog a drain is to use a plunger. Start by plunging the plunger down the drain, then move it up and down several times. If that doesn't work, try pouring some baking soda and vinegar down the drain followed by boiling water. Finally, if all else fails, you can call a professional plumber for help.
