1. Use Hot Water
If that doesn’t work, you can plunge the drain, use a snake or physically remove the clog if you can reach it.
Prevent bathroom sink and tub drain clogs by:
You can make sure your bathroom drains are unclogged by running hot water after taking a shower or brushing your teeth to make sure the warm water dissolves the water-soluble materials in your toothpaste or shampoo. If you have longer hair, invest in a drain saver for your bathtub, that catches longer hair and lets you throw it away, instead of taking it down the pipes where it can clump and cause clogs. When you’re at your bathroom sink, don’t flush hair down the drain.
2. Check the garbage disposal
3. Use a plunger
4. Try vinegar and baking soda
5. Use a Coat Hanger
If you don’t have a plumber’s snake, you can use a wire coat hanger as a substitute by straightening it. Of course, it won’t reach as far as a plumber’s snake would, so it may be long enough to reach some clogs. But it’s worth a try when all else fails! Insert the straightened hanger wire into the kitchen drain or stub pipe to push through or pull out the clog if you can reach it. Be careful not to scratch your sink with the wire.
