Steps
Put on rubber gloves and place a bucket under the sink trap if you can reach it. Lay old towels around the base to catch spills.
Boil a full kettle of water and pour it slowly down the drain in two or three goes. This softens grease and soap scum.
Pour about half a cup of 3 percent hydrogen peroxide down the drain. Let it sit for 10 to 15 minutes to work on organic residue and biofilm.
Follow with another slow pour of hot water to flush the loosened buildup through the pipe.
If water still drains slowly, fill the sink with about 5 cm of water and plunge the drain firmly 10 to 15 times.
Run hot water for a full minute after the drain clears to push the remaining debris past the trap.
If the sink still backs up, the clog is deeper. Stop pouring chemicals and call a plumber or rent a drain snake.
Tips and common mistakes
Never mix hydrogen peroxide with bleach or other drain chemicals, as it can release harmful gas.
Skip this method for a fully blocked drain with standing water, since the peroxide cannot reach the clog.
Repeat the peroxide and hot water routine once a month to keep grease and biofilm from building up.
Do not pour grease or cooking oil down the sink, as it is the most common cause of kitchen clogs.
Questions
Does hydrogen peroxide really clear a clogged drain?
It can help loosen organic buildup like soap scum and biofilm, but it will not dissolve a solid grease or food blockage. Use it as maintenance or a first attempt, then plunge or snake the drain if water still stands.
Can I use hydrogen peroxide in a bathroom or shower drain?
Yes, the same method works on hair and soap residue in bathroom sinks and showers. Pull out visible hair first, since peroxide cannot break down a large hair ball.
Is hydrogen peroxide safe for old pipes?
A 3 percent household solution is mild and generally safe for metal and plastic pipes in short contact. Avoid stronger concentrations and never leave it sitting in the trap for hours.
