How do I unclog a slow drain without harsh chemicals?

Start by removing any visible hair or debris from the drain cover. Then pour boiling water down the drain slowly in two or three stages, letting it work for a few seconds between pours. If that doesn't fully clear it, mix half a cup of baking soda followed by half a cup of white vinegar, cover the drain to force the reaction downward, wait 15 minutes, then flush with hot water. For stubborn clogs, use a drain snake or a simple plastic hair-removal tool, which you can find cheaply at hardware stores. These physically pull out the blockage rather than just pushing it deeper. Regular maintenance with hot water weekly helps prevent buildup from returning.
