How do I unclog a slow bathroom drain myself?

Start by removing the drain stopper if there is one, then use a bent wire or hair catcher tool to pull out any hair and soap buildup near the surface. This alone often fixes the problem. If it's still slow, pour boiling water down the drain, followed by half a cup of baking soda and then half a cup of white vinegar. Let it fizz for 15 to 20 minutes, then flush with more hot water. If that doesn't work, use a cup plunger with a little water in the sink to create suction. For stubborn clogs, a drain snake or zip-it tool can reach deeper blockages. Avoid chemical drain cleaners regularly as they can damage pipes over time.
