Can boiling water unclog a drain? If your drain is clogged with ice cubes — then yes, boiling water can unclog a drain. But if your drain is clogged with the things that normally clog drains — grease, oil, dirt, hair, etc. — then no, boiling water isn't likely to help.
For tough clogs, use a full cup. While that sits, bring a half pot of water (about 4 cups) to boil. Pour this directly into the drain very slowly but steadily to avoid getting burned by splashing water. Allow to sit for 10 to 15 minutes, then run water down the drain to check how freely water flows.
Pouring boiling water is quite risky as it might lead to a steam burn or scalding. Another thing to keep in mind is what type of material you are pouring in into. If you have a porcelain sink, it is likely to crack due to the heat. All in all, pouring boiling water down your drain will only cause issues down the road.
